Answer

Explanation:

Step1: Analyze mole - ratio from equation

The given equation is $2C_2H_2 + 5O_2\rightarrow4CO_2 + 2H_2O$. The mole - ratio of $C_2H_2$ to $O_2$ is $2:5$, and the mole - ratio of $C_2H_2$ to $CO_2$ is $2:4 = 1:2$.

Step2: Calculate moles for 1 mole of $C_2H_2$

If $n(C_2H_2)=1$ mole, using the mole - ratio of $C_2H_2$ to $O_2$ ($2:5$), the moles of $O_2$ used is $\frac{5}{2}\times1 = 2.5$ moles. Using the mole - ratio of $C_2H_2$ to $CO_2$ ($1:2$), the moles of $CO_2$ produced is $2\times1=2$ moles.

Answer:

Two moles of carbon dioxide were produced from this reaction.
