3. two or more substances combine
chemically to form a single
product.Example: A+B --> AB
1. sometimes referred to as double
displacement reactions.Example: AX+BY->AY+BX
4. occur when the direction of a chemical
change can be reversed easily.Example:
A+B《--》C+D
2. involves the reaction between an
element in its free state and a compound.
Example: A+BX-->AX+B
5. a single reactant is broken into two or
more products. Example: AB-->A+B
4. oxidation-reactions are chemical
reactions in which one reactant is reduced
and the other is oxidized. Example:
CuO+H2-->Cu+H2O
6. reactions between a base (alkali) and an
acid. Example: NaOH+HCI-->NaCI+H2O
