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.
True!The properties let us see what has
happened.

combustion to take place?
Oxygen. You can’t have fire
without O2!
True or False?

physical change.
False!Rust is a sign of a
CHEMICAL reaction.
A precipitate is a _________ that forms
from a solution during a chemical
reaction.
Solid!(Like the chucks
floating in the milk when you mixed it
with vinegar…eew!)
