It was determined that H2 was the limiting reactant. What is the excess reactant?

Sam follows the directions on a box of pancake mix. The box says that it makes 10 pancakes, but he is able to make 8 pancakes from the ingredients. In this case, the number 10 represents which type of yield?

Abby mixes 2 moles hydrogen with 1 mole oxygen to produce water. She expects to produce 2 moles water, but she captures 1.5 moles water. In this case, the value 1.5 moles represents which type of yield?

Paige heated 3.00 g mercury (II) oxide (HgO, 216.59 g/mol) to form mercury (Hg, 200.59 g/mol) and oxygen (O2, 32.00 g/mol). She collected 0.195 g oxygen. What was the percent yield of oxygen?%

Methane (CH4, 16.05 g/mol) reacts with oxygen to form carbon dioxide (CO2, 44.01 g/mol) and water (H2O, 18.02 g/mol). Assume that you design a system for converting methane to carbon dioxide and water. To test the efficiency of the system in the laboratory, you burn 5.00 g methane. The actual yield is 6.10 g water. What is your percent yield?%

Which reactant is the limiting reactant?

The excess reactant is the reactant that is used up in a chemical reaction.

The balanced chemical equation for the reaction is shown below: 2HgO 2Hg + O2Did you start with the correct equation?
