Answer 2

Answer:

1) it is because of sugar which is present in the chapati. 

2) Generally, when we add dilute hydrochloric acid to a strong (or concentrated) solution of sulfuric acid, a dehydration reaction takes place. In this reaction, the sulfuric acid strips the hydrochloric acid of its water, effectively converting it to hydrochloric acid gas

3) An MCB is an automatically operated electrical switch. Miniature circuit breakers are intended to prevent damage to an electrical circuit as a result of excess current. They are designed to trip during an overload or short circuit to protect against electrical faults and equipment failure.
