1. the balanced equation below represents a combustion reaction. 2c2h6 + 7o2 → 4co2 + 6h2o what is the total number of moles of co2 produced by the complete combustion of 5.0 moles of c2h6?

Answer

Explanation:

Step1: Identify mole - ratio

From the balanced equation $2C_2H_6+7O_2\rightarrow4CO_2 + 6H_2O$, the mole - ratio of $C_2H_6$ to $CO_2$ is $2:4$ or $1:2$.

Step2: Calculate moles of $CO_2$

If we have $n = 5.0$ moles of $C_2H_6$, using the mole - ratio, the number of moles of $CO_2$ produced is $n_{CO_2}=2\times n_{C_2H_6}$. Substituting $n_{C_2H_6}=5.0$ moles, we get $n_{CO_2}=2\times5.0$ moles.

Answer:

10.0 moles
