the product of the reaction is mgo. describe what you observed in the reaction. then consider the general ab form of a synthesis reaction. write the chemical reaction, balancing the equation so that there are an equal number of atoms of each type in both the reactants and the product.

2Mg + O₂ ⇒ 2 MgO

Explanation:

When the MgO formation reaction is carried out experimentally, it can be seen that Magnesium a solid that has a metallic luster, when a flame is brought closer so that the oxidation reaction of the metal occurs, it is appreciated that a colored flame is produced white for a few moments (the duration of the flame depends on the initial amount of magnesium) and when the reaction finished, the magnesium became a white solid, opaque and very fragile. This is because Mg reacted with oxygen and magnesium oxide formed, which is the white solid.

Synthesis reactions are those in which two or more reagents combine to obtain a new product compound. The general formula for this type of reaction is:

A + B ⇒ C

In the case of the example of the statement, the reaction form of this synthesis would be:

2Mg + O₂ ⇒ 2 MgO

The equation is matched in such a way that there is the same amount of atoms of each species in both reagents and products, thus respecting the principle of conservation of mass.

Clarification: In the synthesis reaction, oxygen is placed in its molecular form (O₂), because the compound is naturally found, it is a simple substance. Magnesium, on the other hand, is found as a simple substance as atoms.
