Answer: Classify each of the following as a combination,

Solution 9QPStep 1 of 2:Here, we are asked to classify the given reactions as a combination, decomposition, single replacement, double replacement, or combustion reaction.Combination reaction: A combination reaction is where two or more elements or compounds combine to form one product. Below is the representation of the reaction:A + B ABDecomposition reaction: A decomposition reaction is where a reactant splits into two or more products. AB A + BSingle replacement reaction: It is a reaction where a reacting element substitutes with the element in the other reacting compound. It is also called as single displacement reaction. Below is the representation of the reaction:A + BC AC + BDouble replacement reaction: It is a reaction where two compounds react and the positive ions and negative ions in the reacting compounds switch places. It is also called as double displacement reaction. Below is the representation of the reaction:AB + CD AD + BCCombustion reaction: A combustion reaction where a carbon-containing compound that is the hydrocarbon burns in oxygen from the air to produce carbon dioxide, water, and energy in the form of heat or a flame.
