Chapter 10 Exam Review

Front

Define actual yield.

Back

The amount of product obtained from a reaction.

Front

What do coefficients represent in a chemical equation?

Back

The number of molecules or moles of a substance.

Front

What is the law of conservation of mass?

Back

Mass is conserved during a chemical reaction.

Front

What is a limiting reactant?

Back

The reactant that is completely consumed in a reaction, determining the amount of product formed.

Front

Define theoretical yield.

Back

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

Front

What is the difference between actual yield and theoretical yield?

Back

Actual yield is the amount obtained from a reaction, while theoretical yield is the maximum possible amount.

Front

What happens to the mass of reactants and products in a closed system?

Back

The total mass remains constant; mass is conserved.

Front

How can you determine the limiting reactant in a reaction?

Back

By calculating the amount of product each reactant can produce and identifying the one that produces the least.

Front

What is the significance of balancing a chemical equation?

Back

It ensures that the law of conservation of mass is followed, with equal numbers of each type of atom on both sides.

Front

What does it mean if a reaction goes to completion?

Back

All of the limiting reactant is used up, and no reactants remain.
