What volume of oxygen, at S. T.P. is required to form complete combustion of 200 `cm^3` of acetylene, and what would be the volume of carbon dioxide formed ?

Explanation

To solve the problem of determining the volume of oxygen required for the complete combustion of 200 cm³ of acetylene and the volume of carbon dioxide produced, we can follow these steps:

### Step 1: Write the balanced chemical equation for the complete combustion of acetylene (C₂H₂).
The balanced equation is:
\[ 2 \text{C}_2\text{H}_2 + 5 \text{O}_2 \rightarrow 4 \text{CO}_2 + 2 \text{H}_2\text{O} \]

### Step 2: Determine the volume of acetylene in liters.
Given that the volume of acetylene is 200 cm³, we convert this to liters:
