Magnesium combustion in air chemical equation: 2Mg + O2 → 2MgO.

A, magnesium interpretation

Magnesium is a metal element, symbol Mg, atomic number 12. silver-white, lightweight, combustion in the air send strong white light. It can make ductile iron and flash powder. Magnesium-aluminum alloy has a wide range of uses, manufacturing aircraft, airships and so on.

Second, the interpretation of combustion

Combustion refers to the oxidation of substances under the action of oxygen, the process of generating energy. This process is usually accompanied by flames and smoke, manifested in the gradual reduction of substances, transformed into gas and ash. During combustion, the chemical energy of the substance is converted into other forms of energy such as heat and light.

Combustion can be divided into two categories: natural combustion and man-made combustion. Natural combustion, such as forest fires, candle burning, etc.; man-made combustion, such as the life of burning fuel, industrial burning waste. Combustion is an important process of human production and life, but also may lead to fire and other disasters.

Three, the interpretation of chemical equations

Chemical equations are mathematical expressions used to describe chemical reactions, which expresses the relationship between the number of reactants and products of the atomic number. The basic format of a chemical equation includes the chemical formulas of the reactants and products, as well as the reaction conditions.

Chemical equations can help us understand the process of a chemical reaction, predict the formation of products, and calculate the molar ratios of reactants and products. In the study of chemistry, chemical equations are a fundamental tool for understanding and analyzing chemical reactions.

The Role of Chemical Equations

I. Clarity of Expression

Chemical equations can succinctly and clearly express the process of a chemical reaction, making it easier for people to understand the material changes of the reaction.

Two, easy to calculate

Chemical equations can be used to calculate the relationship between the amount of reactants and products, which helps to quantitative analysis.

Three, revealing the reaction mechanism

Chemical equations can reveal the steps and mechanisms of chemical reactions, which helps to study the process of chemical reactions in depth.

Four, guiding experiments

Chemical equations can be used as a guide for experiments, helping the experimenter to understand the substances and proportions needed for the reaction.

V. Describing Chemical Properties

Chemical equations can reflect the chemical properties of substances and help analyze and predict chemical reactions.

VI.Conveying Scientific Knowledge

Chemical equations are a universally used scientific symbol that can convey chemical knowledge across language and cultural barriers.
