A container containing two moles of liquid ethanol and the gas of oxygen gas was sparked together to form CO2 & HO2-Identify the limiting reagent?
Correct answer: A. Liquid ethanol
- A. Liquid ethanol
- B. Oxygen gas
- C. Both (A) and (B)
- D. None of the stove
Explanation
So, in the reaction between liquid ethanol and oxygen gas, we need to figure out which one is the limiting reagent. The limiting reagent is the one that gets completely used up and determines the amount of product formed.To do that, we compare the number of moles of ethanol and oxygen gas. If there are not enough moles of one reactant to fully react with the other, then it is the limiting reagent.And when we compare is liquid ethanol.

About Limiting and Excess Reactants
Limiting and excess reactants are identified from the balanced chemical equation and the available amounts of each substance. The limiting reactant determines the maximum product formed, while the excess reactant remains after completion, so questions require mole ratios, theoretical yield and sometimes percentage yield calculations.
