___MG+____O2→____MgO
Answers
GPT-4o mini
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:
\[
\_\_ \text{Mg} + \_\_ \text{O}_2 \rightarrow \_\_ \text{MgO}
\]
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:
\[
2 \text{Mg} + 1 \text{O}_2 \rightarrow 2 \text{MgO}
\]
So, the filled-in blanks are:
\[
\underline{2} \text{Mg} + \underline{1} \text{O}_2 \rightarrow \underline{2} \text{MgO}
\]
