What is the excess reactant for the following reaction given we have 2.6 moles of HCl and Of Ca(OH)₂? Reaction: 2HCl + Ca(OH)₂→ 2H₂O+ CaCl₂

Quizplus · Accepted Answer

To determine the excess reactant, we need to convert the given amount of both reactants to moles. Using the mole ratio from the balanced equation (2 moles of HCl reacts with 1 mole of Ca(OH)2), we can calculate that 2.6 moles of HCl reacts with 1.3 moles of Ca(OH)2. Since we have 11 moles of Ca(OH)2, it is clear that it is in excess and thus the excess reactant. Therefore, the answer is A)Ca(OH)2.
