Question

c₂h₅oh + 3o₂ → 2co₂ + 3h₂o + 1367 kj
what is the mole ratio between water and carbon dioxide?
3 mol h₂o
? mol co₂
fill in the green blank.

Explanation:

Step1: Analyze the balanced chemical equation

In the balanced equation \(C_{2}H_{5}OH + 3O_{2}\to2CO_{2}+3H_{2}O + 1367\space kJ\), the coefficients of \(H_{2}O\) and \(CO_{2}\) are 3 and 2 respectively.

Step2: Determine the mole ratio

The mole ratio of \(H_{2}O\) to \(CO_{2}\) is based on their coefficients. So the ratio is \(\frac{3\space mol\space H_{2}O}{2\space mol\space CO_{2}}\).
