Which formula can be used to calculate the theoretical yield? (5 points)
(amount of reactant + amount of product) x 100
amount of reactants + amount of products
(actual yield + percent yield) x 100
actual yield + percent yield

The formula can be used to calculate the theoretical yield is (Actual yield ÷ percent yield) × 100

The question is incorrect, the correct question is;

Which formula can be used to calculate the theoretical yield?

Actual yield + percent yield

Amount of reactants + amount of products

(Actual yield ÷ percent yield) × 100

(Amount of reactant ÷ amount of product) × 100

In a reaction, the theoretical yield is the amount of product calculated from the stochiometry of the reaction.

The actual yield is the amount of product obtained at the end of the reaction.

From the formula;

percent yield = actual yield ÷ theoretical yield x 100

Making the theoretical yield subject of the formula we have;

theoretical yield =  (Actual yield ÷ percent yield) × 100

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."
