Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases energy in the form of heat or light. Example: fireworks.

Front

What happens to the temperature of an ice cube as it melts?

Back

The temperature of the ice cube stays the same during the melting process until it is completely melted.

Front

How does the mass change after a phase change?

Back

The mass remains the same after a phase change; it is conserved.

Front

What type of bond is formed when a metal bonds with a nonmetal?

Back

An ionic bond is formed when a metal bonds with a nonmetal.

Front

Where are metals located on the periodic table?

Back

Metals are located on the left side of the periodic table.

Front

What is a chemical reaction?

Back

A chemical reaction is a process that involves the rearrangement of the molecular or ionic structure of a substance.

Front

What is the difference between an endothermic and exothermic reaction?

Back

An endothermic reaction absorbs energy, while an exothermic reaction releases energy.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction.

Front

What is a phase change?

Back

A phase change is a transition of matter from one state to another, such as solid to liquid or liquid to gas.

Front

What is an example of a physical change?

Back

An example of a physical change is melting ice or boiling water.
