Chemical Reaction

is the breaking of old bonds and the forming of new chemical bonds between atoms

1. Color Change

2. Formation or disappearance of a solid

3. Formation of a gas

4. Absorption or release of heat

5. the production of light

signs that a chemical reaction has occurred

Composition

Also called combination or synthesis (A+B —> C)

Decomposition

A —> B + C

Single Replacement

A + BC —> B + AC

a. Metals replace metals

b. Nonmetals replace nonmetals

There are two types of Single Replacement

Double Replacement

AB + CD —> AD + CB

a. Precipitate formation

b. Neutralization of an acid and base

c. Production of CO2 gas

There are three types of double replacement

1. Composition

2. Decomposition

3. Single Replacement

4. Double Replacement

5. Hydrocarbon Combustion

What are the five categories of chemical reaction

Hydrocarbon Combustion

is a high-temperature chemical reaction where a hydrocarbon (a compound made entirely of hydrogen and carbon, such as methane, propane, or octane) reacts with oxygen gas.
