FAQs on Index: Hydrogen - Chemistry Class 11 - NEET

1. What is hydrogen and why is it important?
Ans. Hydrogen is the lightest and most abundant element in the universe. It is important because it has the potential to be used as a clean and renewable source of energy. It can be produced from various sources and used in fuel cells to generate electricity without producing harmful emissions.
2. How is hydrogen produced?
Ans. Hydrogen can be produced through various methods such as steam methane reforming, electrolysis, and coal gasification. The most common method is steam methane reforming, where natural gas is reacted with steam to produce hydrogen and carbon dioxide. Electrolysis involves passing an electric current through water to separate hydrogen and oxygen.
3. What are the applications of hydrogen?
Ans. Hydrogen has a wide range of applications. It can be used as a fuel in fuel cell vehicles, providing a clean alternative to traditional combustion engines. It can also be used in industrial processes like refining petroleum and producing fertilizers. Additionally, hydrogen can be used for energy storage and as a feedstock for various chemical reactions.
4. What are the advantages of using hydrogen as an energy source?
Ans. There are several advantages to using hydrogen as an energy source. Firstly, it is a clean fuel that produces only water vapor when used in fuel cells, reducing greenhouse gas emissions and air pollution. Secondly, hydrogen can be produced from diverse sources, including renewable energy, making it a sustainable option. Lastly, hydrogen can be stored and transported, providing flexibility in energy distribution.
5. What are the challenges and limitations of hydrogen as an energy source?
Ans. Despite its potential, there are challenges and limitations associated with hydrogen as an energy source. One challenge is the high cost of production, especially when using renewable energy sources. Another limitation is the lack of a widespread hydrogen infrastructure, including refueling stations for fuel cell vehicles. Additionally, hydrogen has a lower energy density compared to fossil fuels, requiring large storage volumes.
