Detailed explanation-1: -The balanced equation of Mg (s) + O2 (g) → MgO (s) is 2Mg (s) + O2 (g) → 2MgO (s). When balancing chemical equations, we aim for an equal number of each type of atom on both sides. All that is altered are the coefficients. Coefficients are the numbers in front of the molecule.
Detailed explanation-2: -Hence, 2 Mg + O 2 → 2 MgO is an example of oxidation and combination reaction.
Detailed explanation-3: -So, in the given equation, magnesium (Mg) and oxygen (O2) are reactants and magnesium oxide (MgO) is the product.
Detailed explanation-4: -In this equation, Mg is magnesium, O is Oxygen, and the product we get is MgO, known as magnesium oxide. This type of reaction is known as a combination reaction or synthesis reaction.
