Question

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

Explanation:

Step1: Identify moles from equation

From the balanced equation \( \ce{C2H5OH + 3O2 -> 2CO2 + 3H2O + 1367 kJ} \), moles of \( \ce{H2O} \) is 3, moles of \( \ce{CO2} \) is 2.

Step2: Calculate mole ratio

Mole ratio \( \frac{\text{mol } \ce{H2O}}{\text{mol } \ce{CO2}} = \frac{3}{2} \), so the green blank (moles of \( \ce{H2O} \)) is 3.
