Exothermic and Endothermic Reactions

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases energy in the form of heat or light to its surroundings.

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs energy from its surroundings, usually in the form of heat.

Front

What happens during a neutralization reaction?

Back

A neutralization reaction typically involves an acid and a base reacting to form water and a salt, and it is usually exothermic.

Front

Can you give an example of an exothermic reaction?

Back

Combustion of fuels, such as gasoline, is a common example of an exothermic reaction.

Front

What is the significance of displacement reactions in terms of energy?

Back

Displacement reactions are generally exothermic, meaning they release energy when one element displaces another in a compound.

Front

How does respiration relate to exothermic reactions?

Back

Respiration is an exothermic process where glucose is broken down with oxygen to release energy for cellular activities.

Front

What is the role of energy in endothermic reactions?

Back

In endothermic reactions, energy is absorbed from the surroundings, leading to a decrease in temperature of the immediate environment.

Front

What is a common characteristic of exothermic reactions?

Back

Exothermic reactions often result in an increase in temperature of the surroundings.

Front

How do endothermic reactions affect temperature?

Back

Endothermic reactions typically cause a decrease in the temperature of the surroundings as they absorb heat.

Front

What is an example of an endothermic reaction?

Back

The reaction of baking soda with vinegar is an example of an endothermic reaction, as it absorbs heat and feels cold.
