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.
