Welcome to our RU-vid video, "Some Gases Chapter of Class 10 || Science Chemistry || Preparation of Co2 and NH3 | Properties -SEE". This video is specially designed for Nepali students who are preparing for their board exam (SEE) and studying science as a compulsory subject.
In this video, we have covered the fourth chapter from the chemistry section called "Some Gases". We have presented the topics mentioned as per the syllabus of class 10, which we have explained in Nepali language in the most easy and convenient way possible. Our aim is to help students understand the concepts of chemistry with ease and score well in their exams.
Firstly, we have explained the process of laboratory preparation of NH3. Ammonia, also known as NH3, is a colourless gas with a characteristic pungent smell. It is an important compound used in various industries, such as fertilizers, pharmaceuticals, and cleaning agents. We have explained the laboratory preparation of NH3 in detail and also discussed its properties.
Secondly, we have explained the laboratory preparation of Co2. Carbon dioxide, also known as CO2, is a colourless gas with a slightly pungent and acidic smell. It is an important compound used in various industries, such as beverages, fire extinguishers, and refrigeration. We have explained the laboratory preparation of CO2 and also discussed its properties.
Throughout the video, we have also discussed the properties of CO2 and NH3 in detail. We have covered their physical properties, chemical properties, and uses. We have also provided examples and applications of these compounds in our daily life.
Below are some brief questions and answers related to this chapter:
What is NH3?
NH3 is ammonia, a colourless gas with a characteristic pungent smell. It has significant industrial applications in areas like fertilizers, pharmaceuticals, and cleaning agents.
How can NH3 be prepared in the laboratory?
NH3 can be prepared in the laboratory by heating a mixture of ammonium chloride and calcium hydroxide.
What is CO2?
CO2 is carbon dioxide, a colourless gas with a slightly pungent and acidic smell. It is an important compound used in various industries, such as beverages, fire extinguishers, and refrigeration.
How can CO2 be prepared in the laboratory?
CO2 can be prepared in the laboratory by reacting calcium carbonate and hydrochloric acid.
What are the properties of NH3?
NH3 is a colourless gas with a characteristic pungent smell. It is lighter than air and has a boiling point of -33.34°C. It is soluble in water and forms a strong base in solution.
What are the properties of CO2?
CO2 is a colourless gas with a slightly pungent and acidic smell. It is heavier than air and has a boiling point of -78.5°C. It is soluble in water and forms carbonic acid in solution.
We hope this video helps you understand the concepts of chemistry better and score well in your board exams. Good luck!
