Can anyone explain step by step （in details）how did we get the balanced equation？
![**Experiment 30: Magnesium Oxidation in Air**
In a common laboratory experiment, magnesium metal is heated in the presence of air to produce magnesium oxide (MgO). Magnesium oxide is a white solid, but during the experiment, it may appear gray due to the formation of small amounts of magnesium nitride (Mg₃N₂), as some magnesium reacts with nitrogen.
**Task:** Write a balanced equation for each reaction.
**Solution:**
1. **Formation of Magnesium Oxide:**
\[
2\text{Mg}(s) + \text{O}_2(g) \rightarrow 2\text{MgO}(s)
\]
2. **Formation of Magnesium Nitride:**
\[
3\text{Mg}(s) + \text{N}_2(g) \rightarrow \text{Mg}_3\text{N}_2(s)
\]
These reactions illustrate the conversion of magnesium in air, combining with oxygen and nitrogen to form different compounds.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Feb62ec4b-b625-4332-acd2-c86081f32c3c%2Fc12ff493-835f-4fe9-8dee-92827ed46c8d%2Fbxll39m_processed.jpeg&w=3840&q=75)
