Anyone in 2024 sep😂

Who is watching after 2 years ago in 2021 👇👍

Legends watching this in 2024 for the junior 10th😝😝 Edit: Me now preparing for jee in class 11th My god time flies away😅😅

2024 candidates gather here 😢😂

Posted 3 years ago but still it's fresh for 2021-22 batch like. Tq so much sir😊😊

Top 3 questions answers- 1) The acid needed here is Nitric acid and the base needed here is Ammonium hydroxide. The chemical reaction is- HNO3 + NH4OH = NH4NO3 + H2O. 2) a) Vinegar contains acetic acid. b) Milk contains lactic acid. c) Tomatoes contain oxalic acid. d) Apples contain malic acid. 3) Toothpaste is basic in nature. Our mouth contains many acids. We know that a base can neutralize an acid. In this case it becomes neutral and that's why Toothpaste help prevent decay teeth. And another acid that tomatoes contain I think other than oxalic acid is citric acid since it is sour. Sir would you please check my answers?

നാളെ Term - 1 Exam എഴുതാൻ േപാവുന്ന എല്ലാവർക്കും ALL THE BEST

Anyone in 2024 ,???

I think most of them are watching this after 2 year ago in 2021! 👇

hahah ig everyone is watching this rn cos the boards are near😂🙋‍♂️😭

What an explaination sir I was having my online class but this look more interesting than the online class

Legends watching in 2024😊

My science exam is tomorrow and now I am watching this 🙂

Q2) Answer - (a) Acetic Acid , (b) Lactic Acid , (c) Citric Acid, (d) Malic Acid Q3) Answer - when we are not brushing our teeth the microorganisms starts feeding on the remains or which is stuck between our teeth and they start producing acid this acid which is produced from microorganisms will lead to the teeth decay, so to neutralise the acid, we have to use base (toothpaste)

Who are Indians Plz like ur mom promise if u don't

Who is watching this video in 2024

I wish I could give this video more than one like

Q.3 Before we brush our teeth the pH of saliva is less than 7 that is acidic. The toothpaste contains the alkali substance which neutralizes the acid and prevent from tooth decay. If you got your answer hit a like!!!👍👍👍👍👍

Q1)HNO3=acid NH3=base So,HNO3+NH3-----NH4NO3 Q2)a)vinegar-acetic acid b)milk-lactic acid c)Tomato-oxalic acid d)apples-malic acid Q3)Because toothpaste contains fluoride,fluoride fights against the bacteria present in our teeth and helps to prevent the decay in teeth

Who are watching have an exam tomorrow

Tomato sauce has vinegar in it which is used in many materials like pickles as a preservative. Thus, tomato sauce has oxalic and acetic acid. 1.) Ammonium Hydroxide + Nitric Acid ----------> Ammonium Nitrate + Water + Heat NH4OH + HNO3 ---------> NH4NO3 + H2O + Q 2.) a.) Vinegar isused in many materials like pickles as a preservative and has Acetic acid in it. b.) Milk or curd has lactic acid in it c.) Tomato sauce has Oxalic acid present in it d.) Apples is mostly determined by the Malic acid present in it 3.) Major tooth issues like tooth decay is caused when we eat sugary foor such as chocolates, sweets, etc. The bacteria's act upon this sugar and transform it into acid because ( bacteria + sugar = acid ), and this acid eats up the tooth leading to tooth decay. As Toothpaste is a base, it prevents the acid from eating up the tooth by neutralizing it's effect. Hence, Toothpaste prevents tooth decay

1. Ammonium chloride(weak base)+ Nitric acid (strong acid)will give Ammonium nitrate(acidic salt)+ water. 2.(a)Acetic Acid,(b)Lactic Acid,(c)Oxalic Acid,(d)Malic Acid. 3.Toothpaste is actually basic in nature. So, it helps in removing the bacteria that is present in the teeth that contains acid. So, the toothpaste will neutralise the acid and helps in preventing tooth decay.

1)hcl+naoh=n2naoh+h20 2)a) vinegar=acetic acid,milk-lactic acid,tomatoes- oxalic acid,apples- citrus acid 3) toothpaste contains salt which help neutralize the acids and bases presnt in the saliva. thats why brushing our teeth with toothpaste prevents decaying of teeth.

1)NH4NO3____NH4OH+HNO3 2)vinegar -acetic acid Milk. -lactic acid Tomato - oxalic acid Apple -malic acid 3)Tooth paste contain salt it neutrize acid and base so it help to prevent dacay ofteeth

NaOH + HNO3. = NH3NO3 +H2O 2 a) acetic acid b) lactic acid c) oxalic acid d)malic acid 3. The food we eat is a acidic one .... It may cause tooth decay. Toothpaste is a base which neutralize

I swear he is underrated

You are the best teacher in the world❣️❣️ Lots of love from Nepal..🇳🇵 Hope iam gonna get a reply from you plz sir..

Legends are watching in 2022

Sir excellent explanation. And your answers are≈ (1)-Ammonia and Nitric acid.[HNO³+NH³--NH4NO] (2)- -Vinegar~Acitic acid. -Milk~Lactic acid. -Tomato~Oxalic acid+Maleic acid. -Apple~Maleic acid.

Who was seeing this video in 2023

Well explaining sir , and also explain all lessons one by one for 10 the class plz sir

1: HNO3 + NH3 ➡️ NH4NO 2: a: acetic acid. b: Lactic acid c: oxalic acid d: Malic acid 3: Toothpaste have Flouride which prevent the decay of the teeth.

your explanation is clear and slow I LOVED IT

Anyone watching in 2023😅

This is how Chemistry 👨‍🔬 should be taught at school with complete practicals unlike the conventional means of reading the text :/ Thanks a lot Manocha Academy!! 💙

Sir please answer question no 1 I'm confused

4 years ago . Learning Legends are still here . May 2022 .

1.Answer. nitric acidThe industrial production of ammonium nitrate entails the acid-base reaction of ammonia with nitric acid: HNO3 + NH3 → NH4NO. Ammonia is used in its anhydrous form (a gas) and the nitric acid is concentrated. The reaction is violent owing to its highly exothermic nature. 2.a)vinegar-acetic acid b) milk-lactic acid c)tomatoes-oxalic acid d) apple- malic acid 3.Toothpastes are basic in nature. They neutralise the effect of acids and thus prevent tooth from decaying.

Q1 ans: Ammonia and nitric acid are required to have salt ammonium nitrate HNO3 + NH3=NH4NO3 Q2 ans: vinegar-acetic acid apple-malic acid milk-lactic acid tomato-citric acid Q3 ans: Acid is formed in our digestive system for digestion process the acid in our teeth may lead to damage in enamel of the teeth and lead to decay of teeth , the toothpaste is a base it reacts with acid and neutralizes the acid so the toothpaste helps in preventing decay of teeth... Here are my answers to these questions hope to get response and if i m wrong please help me to find the correct answer.. Enjoyed this video too.. Thankyou sir..

2 : a. acetic acid b. Lactic acid c.oxalic acid d. Malic acid 3 : because in toothpaste calcium and phosphate are there to create a strong defense to prevent from cavities

In my school my teacher also said this lesson but I didn't understood.But you said so clearly and now I understood this lesson.Thank you very much sir.

Posted before 4 year but stil its fresh for 2022-2023 bach

Legends are watching this video after 3 years 😂

Super amazing sir ....... can you please answer me the first question In ketchup citric acid is present but it also contain vinegar which means it has acetic acid too 2-vinegar contain acetic acid ....... milk contain lactic acid ......... tomatoes contain oxalic acid and apples contain malic acid 3-fluoride use in toothpaste make the outer hard surface of teeth more resistant towards the acid produced by bacteria present in teeths and gums Kindly sir reply about question no.1 👍👍👍👍

Thanks sir . Even my science teacher couldn't explain it so well 😊

Question 1 Ammonium nitrate is a salt made by the neutralization of HNO3 and NH3 which goes to form NH4NO3 Question 2 Vinegar contains acetic acid CH3COOH Milk contains lactic acid Tomatoes 🍅 have oxalic acid And apple 🍏 has malic acid Question 3 Toothpaste has base in it which neutralizes the acidic food

sodium Benzoate in tomatoes Q1:Ammonia hudroxide and nitric acid NH4OH +HNO3 Q2:a. acetic acid B. lactic acid c. oxalic acid D. maleic acid Q3:our mouth contains bacteria which produces Acid in mouth Toothpaste contain base which reacts with Acid present in mouth and neutilize the reaction which prevents tooth from decaying..😊

You are changing the Indian Education system sir! Teaching practically in India is now Once in a Blue Moon. Thanks for giving a new way to us and clearing our doubts!🙂🙂

Sir your are so good.. the way of your explanation was so easy to understand quickly.. thank you sir

1.HCL and NH4OH 2.Vinegar-Acetic acid CH3COOH Milk-Lactic acid C3H6O3 Tomatoes-Oxalic acid Apples-Malic acid 3.It helps to prevent decay of teeth from excess acid in our tooth by neutralizing it.

1)HNO3 +NH3 = NH4NO 2) a) vinegar : acetic acid b)milk : lactic acid c)tomatoes : oxalic acid d) apples : malic acid 3)When food particles decay in our teeth , the level of acidity in our mouth rises .This leads to tooth decay. Toothpaste are basic to nature . So, this neutralizes the acids and help prevent tooth decay . Sir very understandable. Please make more videos like this ...

Sir please do more videos on biology... It is helpful for competitive exams...

1)ammonium nitrate NH3+HNO3=NH4NO3 Ammonia (base)+nitric acid (acid) =ammonium nitrate 2)a)vinegar-acetic acid B)milk-lactic acid C)tomatoes-oxalic acid D)apples-malic acid 3)when ph of mouth saliva falls below 5.5,the enamel gets weathered. Toothpastes which are generally basic are used for cleaning the teeth that can neutralize the excess acid and prevent tooth decay. Are my answers correct sir

plese what is allotropy.😓😓😍

Sir, tooth decay happens because if a acid expected by germs and bacteria and toothpaste being a base neutralizes the reaction.

Excellent teaching, Sir!It has made chemistry easier..Please make more videos

1.Ammonium hydroxide+ nitric acid gives Ammonium nitrate and water. NH4OH(aq)+ HNO3(aq) gives NH4NO3 +H2O. 2. Vinegar- Acetic acid, apple- malic acid Milk- lactic acid, Tomatoes- oxalic acid 3. Bacteria present in our mouth break glucose and acid is formed, so; we use toothpaste which contains base that neutralize the acid.

Apart from containing oxalic acid, Tomato ketchup also contains acetic acid to preserve it for a long time.

HOMEWORK: •The tomato sauce also contains vinegar (i.e acetic acid) because this acid helps the sauce to Deakin in good condition for a long Time. ANSWER 1: Ammonium hydroxide (NH4OH)+Nitric acid (HNO3)------------>Ammonium Nitrate(NH4NO3)+Water(H2O)+Heat ANSWER 2 : (a)Vinegar has acetic acid in it. (b)Milk has lactic acid present in it . (c)Tomatoes have citric and malic acid and some acids which are in tiny amount amount such as fumaric acid. (d)An apple contains Malic acid in it ANSWER 3:If we eat food and do not rinse our mouth or do not use toothpaste on our teeth gradually our teeth start to decay because of the accumulation of acids on them , to prevent his from happening toothpaste is made from bases as bases neutralize acids , and prevents our teeth from decaying.Thus we should use toothpastes to give a long life to our teeth.. BY THE WAY SIR YOU ARE A ANGEL FOR ME AS I WAS EARLIER NOT THAT GOOD IN SCIENCE AND NOW MY ALL CONCEPTS ARE SUPER CLEAR THANKU FOR MY OUR MORE CORRECTLY OUR HELP ...THANKS A LOT AND BRING VIDEOS LIKE THIS ..

1.HNO3+ NH4OH - NH4NO3+H2O 2.a) acetic acid b) Lactic acid c) Oxalic acid d) malic acid 3. Bacteria present in our mouth may react with sugar and generate acids.This can corrode our tooth enamel which leads to tooth decay. Toothpastes which are basic in nature can neutralize these acids and thus can prevent our tooth from decaying.😅

Thank you sir for this amazing video It's really very helpful THANKS

2022-23 Batch here 😎

Acetic acid vinegar which comprises of 6-7% acetic acid Citric acid citrous fruits - orange lemon etc Tartaric acid grapes tamarind gooseberries Lactic acid sour milk/ curd Malic acid Apple Oxalic acid guava and tomatoes Amino acid proteins Tannic acid tea Carbonic acid carbonated drinks- soda and cold drinks Ascorbic acid amla, vitamin c Thanks 😊 sir 😄😊

Amazing sir . Nice 👍

I understood everything clearly Thanks for this video

Ans 1. HNO3 +NH3 => NH4NO Ans 2. Vinegar. Acetic acid Tomatoes. Citric acid and Malic acid Milk. Lactic acid Apples. Malic acid Ans 3. The Fluride prevents teeth from toothaches because it makes teeth strong and more resistant to acid

How does tooth paste help in tooth decaying answer: - the nature of the toothpaste is alkaline, which is basic . They neutralize the acid produced by bacteria in mouth.

1. NH4OH + HNO3 = NH4NO3 + H2O 2. (a) Acetic acid (b) Lactic acid (c) Citric acid (d) Ascorbic acid 3. Toothpaste is basic in nature and neutralises the acid in our mouth

1. Acid: ammonium(NH3) Base: nitric acid( HNO3) 2. a)Acetic acid b)Lactic acid c)Oxalic acid and 9 more acids d)Malic acid 3.The toothpaste we use in our daily life is a base, the action of bacteria occurs in an acidic medium in our tooth, to prevent tooth decay the base which presents in the toothpaste neutralizes the acid present in our tooth.

As toothpaste are basic in nature so they neutralise the acid produced by bacteria in our teeth and thus help in preventing tooth decay

Sir it is very useful for me to understand Acid, Base and Salt I scored 20 out of 19 thanks sir

Sir you are the best teacher I have seen Hope you become the best teacher in RU-vid 😘😘😘

Moral: all 10std students came here to study for term 1 exam

Posted 4years ago but still it's fresh for 2022 -23 batch 😘😘😘😘

We will understand easily. When we're compared our teachers. So tq so much sir. This is for tenth class am right.

Hlo sir i'm from Nepal and during the online class my science teacher usually show your videos and it is very helpful to all of us and tomorrow is the turn for this chapter soo i'm looking it before our teacher show us...thanks for the great video sir..please pin my comment so that my teacher will see while showing us tomorrow🙏🙏❤️

Q1) Ammonia solution and nitric acid Q2a) Acetic acid b) Lactic acid c) Oxalic acid d) Malic acid Q3) Toothpaste contains a base which neutralizes the acidic substances we eat and prevents tooth decay. Thank you sir. The video was extremely helpful.

1. Ammonium nitrate (NH4NO3) is indeed soluble in water. It is formed by the reaction between ammonium hydroxide (NH4OH) and nitric acid (HNO3). 2. Vinegar contains acetic acid, milk contains lactic acid, tomatoes contain oxalic acid, and apples contain malic acid. These acids contribute to the characteristic taste of the respective food items. 3. The bacteria living on the teeth and gums produce acid, which can erode the tooth enamel and cause dental decay. Fluorine, which is contained in toothpaste, neutralizes this acid and helps to prevent tooth decay.

who is watching in 2020 due to lock down

Answer 1nitric acid and ammonium hydroxide is used to form salt ammonium nitrate and the chemical reaction is NH4N03+H2O. 2.a.Acetic acid b.Lactic acid c. Oxalic acid d.malic acid 3.Toothpaste which is a base helps prevent tooth decay by neutralizing the excess acid realised by the bacteria present in our mouth.

Very good explanation sir It's also easy to understand I request you to make more such videos on chemistry

Vinegar=acetic acid Milk=lactic acid Tomato=oxalic acid Apple=malic acid

who's watching this video in-home quarantine? please reply

Vinegar : acetic acid Apple. : malic acid Tomatoes : oxalic acid

Bhagwan jo jo Mera channel subscribe Kare uske mata Pita ki Umra Bad Jae 🙏🏻🙏🏻

Q1=Nitric acid and Ammonium hydroxide Q2=a) Acetic acid b) Lactic acid c) Oxalic acid d) Malic Acid Q3= It neutralizes the acids left over from our food

1)NH4OH + HNO3 = Ammonium nitrate + H2O 2)a. Acetic acid b.Lactic acid c.Oxalic acid d.Malic acid 3)The covering of the teeth is enamel which is a base. The cavities are acidic in nature. So, it will corrode the enamel layer giving us some teeth sensitivity. So, it is better you brush your teeth with toothpaste because toothpaste is basic helping the enamel and prevent corroding.

Ammonia react with nitric acid to form ammonium nitrate and release of hydrogen

best teacher award goes to u sir

Legend are always legend 2023 -24

My exam starts at 9 o'clock and I am watching this video.

SIR UR SO GREAT I LIKE U R TEACHING THAN OUR SCHOOL TEACHERS 🙏🙏🙏🙏🙏 WE LOVE U SO MUCH THANKU SIR

I heard every class of you sir very good explanation
