Question

What information are provided by the chemical equation $2Mg + {O_2} = 2MgO$

Answer 1

Chemical equations are symbolic representations of chemical reactions that express the reactants and products in terms of their chemical formulae. Symbols are also utilised to represent the direction of the reaction as well as the actual states of the responding entities. Jean Beguin, a sixteenth-century French chemist, was the first to formulate chemical equations.

Complete answer:
An oxide is a type of chemical molecule that contains one or more oxygen atoms along with another element. Metallic oxides are a type of chemical compound that is made up of metal and oxygen. Nonmetal reacts with oxygen in the air to form non-metallic oxides.
$2Mg + {O_2} = 2MgO$
The given chemical equation provides the following chemical information:
Magnesium and Oxygen react to form magnesium oxide.
Two monoatomic molecules of magnesium react with one molecule of oxygen to give two molecules of the compound magnesium oxide.
Magnesium oxide is a simple basic oxide, because it contains oxide ions. It forms magnesium hydroxide, a basic, when it combines with water.
Magnesium oxide is a base because it takes protons (${H^ + }$ ions) (as per Bronsted-Lowry definition of acids and bases). Acids, on the other hand, act as proton donors. Magnesium oxide is a weak base, particularly when compared to group $1$ oxides.
Magnesium oxide ($MgO$), often known as magnesia, is a hygroscopic white solid mineral that occurs naturally as periclase and is a magnesium source.

Note:
Extremely pure at high temperatures, magnesium oxide possesses strong alkali resistance as well as electrical insulation. Light transmittance is enhanced by a high thermal expansion coefficient and thermal conductivity. High-temperature and heat-resistant materials are commonly used.
