Question

Classify the following reaction:2h2o 2h2 o2

Answer 1

Step-by-step explanation:

When a substance or compound dissociates into two or more new compounds then this type of chemical reaction is known as decomposition reaction.

For example,
`2H_(2)O \rightarrow 2H_(2) + O_(2)`

Here, water dissociates into hydrogen and oxygen molecules.

Thus, we can conclude that the given reaction is a decomposition reaction.

The classified form of the following reaction should looke like that :
`2 H2O (l) 2 H2(g) + O2(g)`. WHat about the name of such reaction, I am pretty sure that it is called decomposition. I bet you have the same in the option list, but next time check it carefully.
