Types of Chemical Reactions Review

A synthesis reaction is a type of chemical reaction where two or more reactants 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 two compounds exchange ions or bonds to form two new compounds. Example: $$AB + CD -> AD + CB$$ .

A combustion reaction is a type of chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat. Example: $$C_xH_y + O_2 -> CO_2 + H_2O$$ .

Atoms are never lost or gained in a chemical reaction; they are simply rearranged to form new substances.

The general form of a synthesis reaction is $$A + B -> AB$$ .

The general form of a decomposition reaction is $$AB -> A + B$$ .

The general form of a single replacement reaction is $$A + BC -> AC + B$$ .

The general form of a double replacement reaction is $$AB + CD -> AD + CB$$ .
