To find the mole ratio between water (H₂O) and carbon dioxide (CO₂), let's examine the balanced chemical equation:
[tex]\[
C _2 H _5 OH + 2 O _2 \rightarrow 2 CO _2 + 3 H _2 O + 1367 \text{ kJ}
\][/tex]
In this balanced equation, the coefficients in front of each compound represent the number of moles of that compound involved in the reaction.
- The coefficient for water (H₂O) is 3.
- The coefficient for carbon dioxide (CO₂) is 2.
These coefficients tell us how many moles of each compound are produced or consumed in the reaction. Specifically, for every 2 moles of CO₂ produced, 3 moles of H₂O are produced.
Therefore, the mole ratio between water (H₂O) and carbon dioxide (CO₂) is:
[tex]\[
\frac{3 \text{ mol H}_2\text{O}}{2 \text{ mol CO}_2}
\][/tex]
So, the mole ratio is [tex]\(\frac{3 \text{ mol H}_2\text{O}}{2 \text{ mol CO}_2}\)[/tex].
