Question

1 type the correct answer in the box. use numerals instead of words. given: ch₄ + 2o₂ → co₂ + 2h₂o in the chemical reaction, if 10 moles of h₂o are produced, moles of co₂ are also produced.

Explanation:

Step1: Identify mole - ratio

From the balanced equation $CH_{4}+2O_{2}
ightarrow CO_{2}+2H_{2}O$, the mole - ratio of $CO_{2}$ to $H_{2}O$ is $n_{CO_{2}}:n_{H_{2}O}=1:2$.

Step2: Set up proportion

Let $x$ be the number of moles of $CO_{2}$. We have the proportion $\frac{x}{10}=\frac{1}{2}$.

Step3: Solve for $x$

Cross - multiply gives $2x = 10\times1$, so $x = 5$.

Answer:
