What happens as you increase the temperature of a reaction?
A. More collisions occur and the time required for the reaction increases.
B. Fewer collisions occur and the time required for the reaction decreases.
C. Fewer collisions occur and the time required for the reaction increases.
D. More collisions occur and the time required for the reaction decreases.

D. More collision occur and the time required for the reaction decreases.

Explanation:

When the temperature of a reaction increases ,the reactant molecules gain more energy, enabling more collisions to occur and thus increasing the rate of the reaction.

An increase in the rate of the reaction means that less time is taken for a reaction to take place.

the answer is c. nacl

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
