What is the name of a chemical reaction in which elements and compounds join together to create a single product? (A) Decomposition reaction. (B) Direct combination reaction. (C) Substitution reaction. (D) Combustion reaction. (E) Neutralization reaction.

Since this problem is asking us to name the chemical reaction that creates a single product, let us first discuss chemical reactions. A chemical reaction is a process where reactants are changed into products. Chemical reactions can be shown as chemical equations, where the reactants or the chemicals that start a chemical reaction are written on the left. An arrow is used to separate the reactants from the ending chemicals. The ending chemicals, or products, are written to the right of the arrow.

To answer this problem, let us review two examples of reactions that produce a single product. Let us first take a look at a chemical reaction where carbon reacts with oxygen gas. These two reactants react to form one product, which is carbon dioxide. A second example of a chemical reaction that creates a single product is when magnesium reacts with oxygen gas. The single product produced is the compound magnesium oxide. Both of these examples represent a direct combination reaction. This is a type of reaction where one product is formed from two or more reactants.

When looking back at the option choices, the name of the chemical reaction that creates a single product is answer choice (B), direct combination reaction.
