Q
Chemical Reactions - Synthesis
A
- When two or more simple compounds combine to form a more complicated one.
A + B —> AB
1
Q
Chemical Reaction - Combustion
A
- A combustion reaction is when oxygen combines with another compound to form water and carbon dioxide.
- These reactions are exothermic, meaning they produce heat.
2
Q
Chemical Reactions - Decomposition
A
- Opposite of a synthesis reaction
- A complex molecule breaks down to make simpler ones. These reactions come in the general form
AB —> A + B
3
Q
Chemical Reaction - Single Displacement
A
- When one element trades places with another element in a compound.
A + BC —> AC + B
4
Q
Chemical Reactions - Double Displacement
A
- The anions and cations of two different molecules switch places, forming two entirely different compounds.
AB + CD —> AD + CB
5
Q
Chemical Reactions - Acid Base
A
- Special kind of double displacement reaction that takes place when an acid and base react with each other.
- The H+ ion in the acid reacts with the OH- ion in the base, causing the formation of water.
HA + BOH —> H2O + BA
6
Q
Exothermic Reaction
A
Accompanied by the release of heat
7
Q
Endothermic
A
Accompanied by or requiring the absorption of heat
8
Q
Homogeneous
A
Consisting of all parts of the same kind
9
Q
