What is theoretical yield?

• the maximum amount of product that could be formed from a given amount of reactant.

• the amount of product that actually forms when a chemical reaction is carried out in a laboratory.

• the efficiency of a particular chemical reaction within the respective conditions.

• the reactant that is used up first in a reaction.

True or False?
The actual yield is usually greater than the theoretical yield.

• False

• True

When reacting Na with Cl₂, we calculated that the theoretical yield should be 13 grams. Our actual yield was 12.5 grams. What is the percent yield?

• 90.4%

• 104%

• 96.15%

• 1.04%

2Fe₂O₃ + 3C → 4Fe + 3CO₂

You add 28 grams of carbon. You find the actual yield to be 81.2 grams of CO₂. What is the percent yield of CO₂? (Hint: calculate theoretical yield of CO₂ first)

• 58.83%

• 308%

• 6435%

• 79.14%

Given the pictured equation, how may moles of hydrogen gas (H2) would be produced from 1.00 mole of Zinc (Zn) if there was a 85.0% yield?

• .850 mole

• .750 mole

• 1.00 mole

• There is no way to determine this answer.
