Endothermic and Exothermic Assessment

Front

What is an endothermic reaction?

Back

A reaction that takes in heat/energy.

Front

What happens to the temperature of a solution when ammonium nitrate dissolves in water?

Back

The temperature of the solution decreases, indicating an endothermic reaction.

Front

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

Back

Higher energy.

Front

If a chemist conducts an endothermic reaction starting at 25 degrees Celsius, what could be a reasonable ending temperature?

Back

15 degrees Celsius.

Front

What type of reaction occurs in a hand warmer?

Back

Exothermic.

Front

Define exothermic reaction.

Back

A reaction that releases heat/energy.

Front

What is the effect of an endothermic reaction on the surrounding environment?

Back

It absorbs heat, causing the surroundings to feel cooler.

Front

Give an example of an endothermic process.

Back

Photosynthesis in plants.

Front

What is the main characteristic of an exothermic reaction?

Back

It releases energy, usually in the form of heat.

Front

How can you identify an endothermic reaction in a lab?

Back

By measuring a decrease in temperature during the reaction.
