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.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
