The wolf goes extinct, and the deer population has no predator to worry about. They graze the land. Because there is no more food. Some of the deer begin to bite at each other, while others die of starvation. What is the limiting factor to the deep population?

• Competition

• Overcrowding

• Predator-Prey Relationships

• Herbivory Effect

Why is it important to identify the limiting reagent?

• The limiting reagent speeds up the reaction.

• The limiting reagent controls the amount of product formed.

• If there is no limiting reagent, the reaction will not occur.

• No stoichiometry calculations can be done without a limiting reagent.

When does a chemical reaction stop?

• When the lab is finished.

• When the excess reactant is used. up

• When the limiting reactant is used up.

• Chemical reactions never stop.

The limiting reactant . . .

• slows the reaction down.

• is used up first.

• is the reactant that is left over.

• controls the speed of the reaction.

In a chemical reaction, what does the term 'limiting reactant' refer to?

• The reactant that is completely consumed first, limiting the amount of product formed.

• The reactant that is present in excess and remains after the reaction.

• The reactant that speeds up the reaction.

• The reactant that is least reactive.

Which of the following best describes the role of a limiting reactant in a chemical reaction?

• It determines the maximum amount of product that can be formed.

• It increases the rate of the reaction.

• It is the reactant that is left over after the reaction.

• It is the reactant that can be regenerated.
