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

Aug 10, 2017

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

#### Explanation:

${H}_{2} O \left(l\right) + \Delta \rightarrow {H}_{2} \left(g\right) + \frac{1}{2} {O}_{2} \left(g\right)$

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

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

$N {H}_{3} \left(g\right) + \Delta \rightarrow \frac{1}{2} {N}_{2} \left(g\right) + \frac{3}{2} {H}_{2} \left(g\right)$

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