fill in the blanks and Balance the following the chemical equation:

Question

___MG+____O2→____MgO

Answer 1

To balance the chemical equation for the reaction of magnesium (Mg) with oxygen (O₂) to form magnesium oxide (MgO), we need to ensure that the number of atoms of each element is the same on both sides of the equation.

The unbalanced equation is:

$$\text{Missing open brace for subscript}$$

1. In the reaction, one magnesium atom will react with half a molecule of oxygen to form one molecule of magnesium oxide.
2. Since O₂ has two oxygen atoms, we will need two magnesium atoms to react completely with it.

The balanced equation is:

$$2\text{Mg}+1{\text{O}}_2\to 2\text{MgO}$$

So, the filled-in blanks are:

$$\underset{―}{2}\text{Mg}+\underset{―}{1}{\text{O}}_2\to \underset{―}{2}\text{MgO}$$
