Gasohol is a fuel containing liquid ethanol $\left(\mathrm{C}_{2} \mathrm{H}_{6} \mathrm{O}\right)$ that burns in oxygen gas to give carbon dioxide and water gases. (7.4,7.7,7.8) a. Write the balanced chemical equation. 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 $88 \mathrm{~g}$ of $\mathrm{CO}_{2}$, how many grams of $\mathrm{O}_{2}$ are used up in the reaction? d. If you burn $125 \mathrm{~g}$ of $\mathrm{C}_{2} \mathrm{H}_{6} \mathrm{O}$, how many grams of $\mathrm{CO}_{2}$ and $\mathrm{H}_{2} \mathrm{O}$ can be produced?
Chemical Quantities and Reactions
The Mole
Gasohol is a fuel that contains ethanol (C2H6O) that burns in oxygen (O2) to give carbon dioxide and water. C2H6O(g) + 3O2(g) ⟶ 2CO2(g) + 3H2O(g) a) How many moles of O2 are needed to completely react with 4.0 moles of C2H6O? b) If a car produces 54 g of CO2, how many grams of O2 are used up in the reaction? c) How many grams of CO2 are produced if 50.0 g of C2H6O are mixed with 74.5 g of O2?
