Question

Can ammonia, water, or argon be decomposed by chemical change?

Answer 1

Well, certainly water and ammonia can be decomposed by chemical change........

Explanation:

`H_2O(l) + Delta rarr H_2(g) + 1/2O_2(g)`

As written, the reaction is ENDOTHERMIC, and we could input the energy by supplying an electric current......

And, more difficult...........

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

However, argon is a mono-atomic element......and this cannot be decomposed by chemical change........
