Question

If `100*mL` of ammonia gas are decomposed into its constituent elements what volumes of dinitrogen, and dihydrogen would result?

Answer 1

Well, if we could decompose gaseous ammonia........to gives its constituent elements..........

Explanation:

`NH_3(g) rarr 1/2N_2(g) + 3/2H_2(g)`

And so at STP, if `100*mL` of ammonia are decomposed according to the given equation, `50*mL` of dinitrogen, and `150*mL` dihydrogen will result.
