Sir u r the best I was studying from Mohit sir on unacademy since last year but never thought to study from other teachers now I m amazed all the teachers are best THANKS A LOT SIR All concepts got cleared
Thank you very muuuuuuuuch sir❤😊😊😊😊😊😊😊😊😊 Even in our coaching centre sir made this method so big Bit you just finished it in two steps REALLY APPRECIATE IT KEEP IT UP THANK YOU 😊
thankyou so much sir , your way of simple explanation in very good and crisp my concepts are clear [I also have unacademy plus subscription but iam watching your videos]
Sir ye jitni bhi reaction aapne likhi inhe yaad karna padega kya? Aur itti saari yaad kaise karnge , ese to hazaro reaction hongi.? Ya koi tarika hai yaad krne ka?
At 16:34 , Why has sir done 8/3 for Fe in Fe3O4 but in the previous question of Cr in K2Cr2O7 he didnt take ..he didnt do so. There seems to be no uniformity. Pleade make it clear.
in the previous question also u should multiply the change in oxidation state of K2Cr2O7 by 2 as there are 2 atoms. but also notice that in H2O2, we have to multiply by 2 as there are 2 atoms and when we take the ratio, it is cancelled out. So there is uniformity, we have to always multiply the number of atoms and change in oxidation state
#compitishun sir should we balance product side based on trail and error method.I am having a doubt sir see in O.N method we should identify the change in O.N of elements and cross multiply them right my doubt is should we only multiply those to reactants side,or we must multiply to product side also. Iam not getting this please reply If anyone knows as soon as possible
sir at 24:30 you said that -3 is not allowed for phosphorus and also you said that is range is in between -3 to +5 and lastly you assigned phosphorus -3 oxidation number
basically sir wanted to say -6 at that point coz if you will take cu(+2) then you will have to take P as(-6) that is not allowed for Phosphorus as P has oxidation state in b/w -3 and 5 . that was a sleep of tongue though...
Sir from ion electron method my answers is coming different, I have cross checked the atoms numbers as well as charge conservation..so is it possible to get multiple balanced answers? In question 26:31 timing, cuprous phosphate and nitrate ion wala question
Oxidation state +8/3 se +3 change hua. So oxidation hua he kyunki oxidation state bada he due to loss of 3 - 8/3 = 1/3 electrons for each Fe. So, 3*1/3 = 1 electron for 3Fe. We always take positive value so take mod of 3 - 8/3
Change me sign nhi dekhte 'Change' me sirf me sirf magnitude dekha jata hai generally. Eg of 150 is one time decreased and one time increased by 10. Then change would be of 10 in each case. You dont need to say + 10 or -10. (Unless sign is given in option). Just consider the magnitude for changes in general.
12:08 please anyone help me....sir ne right side O2 ka oxidation number 0 gai to left side ka total change sir ne (H2O2 ka )oxidation 2 kyo likha ....dono side to O2 hi hai ?? Please help 🙏
Bro idhar left (reactants side ) mein h202 hai mtlb peroxide iski vjh se o2 ka -1 aayega and right vaale mein toh bas element hai iski vjh se 0 hoga bro
