Match the chemical equation to the correct type of chemical reaction. mg3(po4)2 + h2 -> mg + h3po4 2nacl -> 2na + cl2 2na + cl2 -> 2nacl naoh + cuso4 -> na2so4 + cu(oh)2 2c2h6 + 7o2 -> 4co2 + 6h2o 1. synthesis reaction 2. decomposition reaction 3. combustion reaction 4. single-displacement reaction 5. double-displacement reaction

 : Single replacement

: Decomposition

: Synthesis

: Double displacement

: Combustion

Explanation:- Synthesis is a type of chemical reaction when two reactants combine to give a single product.

Decomposition reaction is a type of chemical reaction in which one reactant gives two or more than two products.

Combustion is a type of chemical reaction in which hydrocarbons burn in the presence of oxygen to form carbon dioxide and water along with heat.

A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution.

A double displacement reaction is one in which exchange of ions take place.
