If ten volumes of dihydrogen gas reats with five volumes of dioxygen gas, how many volumes of water vapour would be produced?

Explanation

To solve the problem of how many volumes of water vapor would be produced when 10 volumes of dihydrogen gas react with 5 volumes of dioxygen gas, we can follow these steps:

### Step-by-Step Solution:

1. **Write the Balanced Chemical Equation**:
The reaction between dihydrogen (H₂) and dioxygen (O₂) to form water (H₂O) can be represented by the balanced equation:
\[
2H_2 + O_2 \rightarrow 2H_2O
