sulphuric acid is added to it. If the gas evolved is tested first with dry and then with

wet blue litmus paper, in which case will the litmus paper change colour ? Give

reason for your answer. What inference can be drawn about the nature of the evolved

gas? Support your answer with chemical equation for the reaction.

14. Assertion (A) When electricity is passed through water, hydrogen

and oxygen gas are obtained. This is an example of a

decomposition reaction

Reason (R): A reaction which a reactant breaks down to form

simpler products is called a decomposition reactionbinod x²+x5+x²+(-2x+4)/(x+3)1 g of solid sodium chloride is taken in a clean and dry test tube and 2 mL of conc.
