Types of chemical reactions

1. Combination Reaction 2. Decomposition Reaction 3. Single Replacement Reaction 4. Double Replacement Reaction

A combination reaction is a type of chemical reaction where two or more substances combine to form a single product. Example: $$A + B -> AB$$ .

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler products. Example: $$AB -> A + B$$ .

A single replacement reaction is a type of chemical reaction where one element replaces another in a compound. Example: $$A + BC -> AC + B$$ .

A double replacement reaction is a type of chemical reaction where the anions and cations of two different compounds switch places, forming two new compounds. Example: $$AB + CD -> AD + CB$$ .

The general formula for a combustion reaction is: $$C_xH_y + O_2 -> CO_2 + H_2O$$ .

The general reaction scheme for a decomposition reaction is: $$AB -> A + B$$ .

This is a Double Replacement Reaction.

This is a Decomposition Reaction.

This is a Single Replacement Reaction.
