Identify the type of reaction represented by each equation.

A: H2 + Cl2 → 2HCl

B: CH4 + 2O2 → CO2 + 2H2O

Equation A represents a______
reaction, and equation B represents a ______reaction.

Respuesta :

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

Explanation :

  • Equation A : [tex]H_2+Cl_2\rightarrow 2HCl[/tex]

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.

  • Equation B : [tex]CH_4+2O_2\rightarrow CO_2+2H_2O[/tex]

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.
