Question

c₂h₅oh + 3o₂ → 2co₂ + 3h₂o + 1367 kj
what is the mole ratio between
water and carbon dioxide?
\frac{3\text{ mol }h_2o}{?\text{ mol }co_2}
fill in the green blank.

Explanation:

Step1: Identify moles from equation

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

Step2: Determine mole ratio

Mole ratio \( \frac{\ce{H2O}}{\ce{CO2}} = \frac{3\ \text{mol}\ \ce{H2O}}{2\ \text{mol}\ \ce{CO2}} \). So the blank is 2.

Answer:

2
