The only sure evidence for a

chemical reaction is

-the formation of a gas-a color change

-the production of one or more new substances-changes in properties

the production of one or more new

substances

True or False?

In a chemical reaction, chemical bonds are formed

or broken.

True! Bonds have to

break or form to make new

substances.

True or False?

A chemical reaction may be

detected by observing changes in the properties of

matter.
