Answer:
A) Ethanol is the Limiting reactant
B) 5.36 grams
Explanations:
The chemical reaction for the chemical combustion of ethanol is expressed as:
Determine the mass of ethanol
Mass of ethanol = density * volume
Mass of ethanol =0.789 * 5.8
Mass of ethanol = 4.58 grams
Determine the mass of Oxygen
Mass of Oxygen = 12.5 grams
Determine the mole of ethanol and oxygen
For the mole of oxygen
Since the mole of ethanol is lower than that of oxygen, hence the limiting reactant is ethanol
Part B: According to stoichiometry, 1mole of ethanol produces 3 moles of water, the mole of water required will be expressed as:
Therefore the theoretical yield of H2O is 5.36grams
