Endothermic and Exothermic Assessment

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 to the temperature during an exothermic reaction?

Back

The temperature increases during an exothermic reaction.

Front

What happens to the temperature during an endothermic reaction?

Back

The temperature decreases during an endothermic reaction.

Front

In an exothermic reaction, do the reactants or products have higher energy?

Back

The reactants have higher energy than the products in an exothermic reaction.

Front

In an endothermic reaction, do the reactants or products have higher energy?

Back

The products have higher energy than the reactants in an endothermic reaction.

Front

Give an example of an exothermic reaction.

Back

Combustion of fuels, such as burning wood or fireworks, are examples of exothermic reactions.

Front

Give an example of an endothermic reaction.

Back

The reaction between baking soda and vinegar is an example of an endothermic reaction.

Front

What is the role of energy in chemical reactions?

Back

Energy is either absorbed or released during chemical reactions, determining whether the reaction is endothermic or exothermic.

Front

How can you identify an exothermic reaction in a laboratory setting?

Back

An exothermic reaction can be identified by a noticeable increase in temperature or the release of light.
