1. combination reactions.
2. decomposition reaction.
3. displacement reaction.
4. double displacement reaction.

❥︎$\underline\bold\blue{ 1)combination reaction}$

______________________________________

• when two or more reactants combined in a reaction to form a single product it is called a combination reaction.
• CaO + H2O _____> Ca(OH)2 + Heat

______________________________________

• the reaction in which there is only one reactant giving rise to two or more products is called the decomposition reaction.

or,

• the chemical reaction in which two or more products are formed from a single reactant it's called decomposition reaction.
• C12H22O11 ______> 12C + 11 H2O

______________________________________

• the reaction in which the place of the ions of a less reactive element is a compound is taken by another more reactive element by formation of its own ions it's called displacement reaction.
• CuSO4 + Fe____> FeSO4 + Cu

❥︎$\underline\bold\orange{4) double displacement reaction }$

______________________________________

• direction in which the ions in the reactants are exchanged to former precipitate are called double displacement reaction.
