Question

according to the following reaction, if five moles of oxygen were to react completely, how many moles of water would be produced? 2h₂ + o₂ → 2h₂o. report your answer as a whole number without any decimal places. provide your answer below: mol

Explanation:

Step1: Identify mole - ratio

From the reaction $2H_2 + O_2
ightarrow2H_2O$, the mole - ratio of $O_2$ to $H_2O$ is $1:2$.

Step2: Calculate moles of water

If $n(O_2) = 5$ moles, and $\frac{n(H_2O)}{n(O_2)}=\frac{2}{1}$, then $n(H_2O)=2\times n(O_2)$.
So $n(H_2O)=2\times5 = 10$ moles.

Answer:

10
