Question

2NaH → 2Na + H2 is an example of a combination reaction.

(a) True

(b) False

I had been asked this question by my college director while I was bunking the class.

Question is taken from Redox Reactions and Electrode Processes topic in chapter Redox Reactions of Chemistry – Class 11

Answer 1

Correct answer is (b) False

Easy explanation: The above statement is considered to be false because it is a decomposition reaction as sodium hydride is broken down into Sodium and hydrogen. A combination of reaction results in the formation of a new compound instead of breaking down.
