Chapter 6, Problem 110AQP(choose chapter or problem)
Gasohol is a fuel that contains ethanol \(\left(\mathrm{C}_{2} \mathrm{H}_{6} \mathrm{O}\right)\), which burns in oxygen \(\left(\mathrm{O}_{2}\right)\) to give carbon dioxide and water. (6.6, 6.7)
a. Write the balanced equation for the combustion of ethanol.
b. How many moles of \(\mathrm{O}_{2}\) are needed to completely react with 4.0 moles of \(\mathrm{C}_{2} \mathrm{H}_{6} \mathrm{O}\) ?
c. If a car produces 88 g of \(\mathrm{CO}_{2}\), how many grams of \(\mathrm{O}_{2}\) are used up in the reaction?
d. If you add 125 g of \(\mathrm{C}_{2} \mathrm{H}_{6} \mathrm{O}\) to your fuel, how many grams of \(\mathrm{CO}_{2}\) and \(\mathrm{H}_{2} \mathrm{O}\) can be produced from the ethanol?

ANSWER:Step 1 of 5
a.Here we have to write the balanced equation for the combustion of ethanol.
Given:
In this question it has been given that ethanol \(\left(\mathrm{C}_{2} \mathrm{H}_{6} \mathrm{O}\right)\) on combustion in oxygen \(\left(\mathrm{O}_{2}\right)\) give \(\mathrm{CO}_{2}\) and water.
The balanced chemical reaction is,
\(\mathrm{C}_{2} \mathrm{H}_{6} \mathrm{O}+3 \mathrm{O}_{2} \rightarrow 2 \mathrm{CO}_{2}+3 \mathrm{H}_{2} \mathrm{O}\)
