Question

If You are given 14 moles of C2H5OH(Ethanol) and 13 moles of O2( Oxygen), how

many moles of the limiting reactant is produce? C2H5OH + O2 -> CH3COOH +
H2O

Answer 1

Step-by-step explanation:

1 ) first u have to balance the equation but in this case it is already balanced.

2) checking for the limiting reactant:

13 mol O2 × (1mol H2O / 1mol of O2) = 13 mol of H2O

14 mol of ethanol × (1mol H2O/ 1molof ethanol) = 14 mol of H2O

the less amount of moles produced from the O2 so the limiting reactant is oxygen

3) calculating the products moles

13 mol O2 × (1mol H2O / 1mol of O2) = 13 mol

13 mol O2 × (1mol Ch3Cooh / 1mol O2) = 13 mol

note: the ratios obtained from the balanced equation

4) the excess reagent is the ethanol 1 mol will be remain
