Question
Given below are two statements labeled as Assertion (A) and Reason (R).
Assertion(A): Hydrogen at present cannot be used as fuel on a large scale.
Reason(R): Storage of hydrogen is dangerous as it is a light gas that is very explosive.
Select the most appropriate answer from the options given below:
- Both A and R are true, and R is the correct explanation of A
- Both A and R are true, but R is not the correct explanation of A.
- A is true, but R is false.
- A is false, but R is true.
Hint:
Both A and R are true, and R in the correct explanation of A
The correct answer is: Both A and R are true, and R is the correct explanation of A
Hydrogen is not easily available and cost of production is high hence, it cannot be used as a fuel on large scale.
Even small amounts of liquid hydrogen can be explosive when combined with air, and only a small amount of energy is required to ignite it if it is not handle properly
