Types of Chemical Reactions

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

A double replacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds. The general formula is: AB + CD -> CB + AD.

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

A decomposition reaction is a chemical reaction in which a single compound breaks down into two or more simpler products. It can be represented as: compound -> element + element.

The Law of Conservation of Mass states that matter cannot be created or destroyed in a chemical reaction; the mass of the reactants equals the mass of the products.

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

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

The products of a combustion reaction involving hydrocarbons are carbon dioxide (CO2) and water (H2O).

The general formula for a chemical reaction can be represented as: Reactants -> Products.

An example of a synthesis reaction is: $$2H_2 + O_2 -> 2H_2O$$ .
