Identify the type of reaction represented by each equation. a: h2 + cl2 → 2hcl b: ch4 + 2o2 → co2 + 2h2o equation a represents reaction, and equation b represents a .

Equation A represents a combination reaction, and equation B represents a combustion reaction. Hope this helps!

Answer : Equation A represents a combination reaction, and equation B represents a combustion reaction.

Explanation :

In this reaction, hydrogen react with the chlorine to form a single product as hydrogen chloride. So, this reaction is a combination reaction.

Combination reaction : It is a type of chemical reaction in which two or more  reactants combine to produce a single product.

In this reaction, methane is a hydrocarbon react with the oxygen to give carbon dioxide and water as a product. So, this reaction is a combustion reaction.

Combustion reaction : A type of chemical reaction where a hydrocarbon molecule react with the oxygen to produces carbon dioxide and water as a product.

Hence, the Equation A represents a combination reaction, and equation B represents a combustion reaction.
