Question
Identify the following type of reaction:2 H2O → 2 H2 + O2Question 18Select one:a.Decomposition b.Synthesisc.Single displacementd.Combustion
Solution
The given reaction is: 2 H2O → 2 H2 + O2.
This is a decomposition reaction.
In a decomposition reaction, a single compound breaks down into two or more simpler substances (elements or simpler compounds). Here, water (H2O) is breaking down into hydrogen (H2) and oxygen (O2).
So, the correct answer is a. Decomposition.
