Unit 5 Review

Front

What is the formula for percent yield?

Back

(actual yield / theoretical yield) × 100%

Front

Which is usually smaller, actual yield or theoretical yield?

Back

Actual yield

Front

How is the actual yield often expressed?

Back

As a percentage of the theoretical yield

Front

What is the actual yield of a reaction?

Back

The amount produced, usually less than the maximum expected (theoretical yield)

Front

What does the theoretical yield represent?

Back

The maximum amount of product that can be produced from a given amount of reactants under ideal conditions.

Front

What factors can affect the actual yield of a reaction?

Back

Purity of reactants, reaction conditions, side reactions, and measurement errors.

Front

What is the significance of percent yield in chemistry?

Back

It indicates the efficiency of a reaction and helps assess how well a reaction proceeds.

Front

How do you calculate the theoretical yield from a balanced chemical equation?

Back

Use stoichiometry based on the mole ratios from the balanced equation.

Front

What is stoichiometry?

Back

The calculation of reactants and products in chemical reactions based on the conservation of mass.

Front

In the reaction 2 Na + Cl2 → 2 NaCl, how many moles of NaCl are produced from 2 moles of Na?

Back

2 moles of NaCl.
