Chloroform, CHCl3, reacts with chlorine, Cl2, to form carbon tetrachloride, CCl4, and hydrogen chloride, HCl. In an experiment 25 grams of chloroform and 25 grams of chlorine were mixed. In the laboratory, 10 grams of CCl4 are actually produced. Which is the limiting reactant? What is the theoretical yield of CCl4 in grams? 2. Limiting Reagent: Theoretical Yield: % Percent Yield: xcess (2.5 pts.) (2.5 pts.) (2.5 pts.) (2.5 pts.) reactant remaining

In the following chemical reaction, 2 mol of A will react with 1 mol of B to produce 1 mol of A2B without anything left over: 2A+B→A2B But what if you're given 2.8 mol of A and 3.2 mol of B? The amount of product formed is limited by the reactant that runs out first, called the limiting reactant. To identify the limiting reactant, calculate the amount of product formed from each amount of reactant separately: 2.8 mol A×1 mol...
