Given the following equation: 2 K + Cl2 - --> 2 KCl

How many moles of KCl are produced from 2.00 moles of K and excess Cl2.?

2 moles of KCl will be produced

Explanation:

Given parameters:

Number of moles of K = 2 moles

Unknown:

Number of moles of KCl produced = ?

Solution:

To solve this problem;

Obtain a balanced chemical equation:

2K + Cl₂ → 2KCl;

Since K is the limiting reactant, its amount will determine the extent of this reaction.

From the balanced equation;

2 moles of K will produce 2 moles of KCl

Given that 2 moles of K reacted, 2 moles of KCl will be produced
