Single Replacement:
A single replacement reaction is a type of chemical reaction where an element reacts with a compound and takes the place of another element in that compound.
A+BC=AC+B
Double Replacement:
When parts of two ionic compounds are exchanged making two new compounds.
AB+CD=AD+CB
Synthesis:
Several reactants combine to make a single product
A+B=AB
Decomposition:
One reactant decomposes into two or more products
AB=A+B
Combustion:
When any hydrocarbon reacts with oxygen, it always creates carbon dioxide and water.
Hydrocarbon+ Oxygen= carbon dioxide + water
How to use the activity series:
In a single replacement reaction, if the first single metal is above the other metal in the compound in the activity series then a reaction occurs. If it is below there is no reaction.
How to use solubility rules:
In order to predict whether a precipitate will form in a reaction, the solubility of the substances involved must be known. There are rules or guidelines determining solubility of substances. If a substance involved is not soluble, the reaction forms a precipitate. Use the rules above to determine if a substance is soluble or if it's a precipitate.
