Exo/endo Reactions

Front

What is the difference between exothermic and endothermic reactions?

Back

Exothermic reactions produce heat, while endothermic reactions absorb heat.

Front

What happens to energy when new bonds are formed in a chemical reaction?

Back

Energy must be released when new bonds are created.

Front

What does the prefix 'endo' signify in chemical terms?

Back

The prefix 'endo' means 'in'.

Front

How can you identify an exothermic reaction based on heat production?

Back

An exothermic reaction is identified as one that produces heat.

Front

What effect does an exothermic reaction have on its surroundings?

Back

An exothermic reaction will make its environment feel warmer.

Front

What is an example of an exothermic reaction?

Back

Combustion of fuels, such as burning wood or gasoline.

Front

What is an example of an endothermic reaction?

Back

Photosynthesis in plants, where energy is absorbed from sunlight.

Front

What is the role of activation energy in chemical reactions?

Back

Activation energy is the minimum energy required to initiate a chemical reaction.

Front

How do temperature changes relate to exothermic and endothermic reactions?

Back

Exothermic reactions increase the temperature of the surroundings, while endothermic reactions decrease it.

Front

What is the law of conservation of energy in the context of chemical reactions?

Back

The law states that energy cannot be created or destroyed, only transformed from one form to another.
