Question

consider the reaction for the combustion of acetylene. 2c₂h₂(g) + 5o₂(g) → 4co₂(g) + 2h₂o(g) how many liters of c₂h₂ react with 66.0 l of oxygen, assuming the reaction is at stp? ? l c₂h₂

Explanation:

Step1: Find volume ratio of reactants

From balanced equation: $\frac{V_{\text{C}_2\text{H}_2}}{V_{\text{O}_2}} = \frac{2}{5}$

Step2: Calculate volume of $\text{C}_2\text{H}_2$

$V_{\text{C}_2\text{H}_2} = 66.0\ \text{L} \times \frac{2}{5} = 26.4\ \text{L}$

Answer:

26.4
