Question

What type of reaction is represented by each of the following equation?

$\mathrm{A}+\mathrm{B}\to \mathrm{AB}$

Answer 1

1. Combination reaction

A synthesis reaction is another name of a combination reaction. In this reaction, two more multiple elements or compounds undergo combination and result in one compound only.

In the above-given reaction, two different types of reactants (A and B) are reacting with each other to form only one single product (AB). This type of reaction is classified as a combination reaction.

2. Example of combination reaction

An example of a combination reaction is given below:

$$\begin{gathered} \mathrm{Mg}\left(\mathrm{s}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\to 2\mathrm{MgO}\left(\mathrm{s}\right) \\ \mathrm{Magnesium}\mathrm{Oxygen}\mathrm{Magnesium}\mathrm{oxide} \end{gathered}$$

In this reaction, Magnesium combines with Oxygen in order to form Magnesium oxide. Thus, the type of reaction is a combination reaction.
