**Combination Reaction**
A combination reaction is a type of chemical reaction in which two or more substances combine to form a single product. In this case, magnesium ribbon (Mg) is reacting with nitrogen gas (N₂) to form solid magnesium nitride (Mg₃N₂).
**Formation of Magnesium Nitride**
When magnesium ribbon is burned in an atmosphere of nitrogen gas, the following reaction takes place:
3Mg + N₂ → Mg₃N₂
This means that three atoms of magnesium combine with one molecule of nitrogen gas to form one molecule of magnesium nitride.
**Balancing the Equation**
To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. In this case, we have:
3 magnesium atoms on the left side
2 nitrogen atoms on the left side
3 magnesium atoms on the right side
2 nitrogen atoms on the right side
**Classification as a Combination Reaction**
Based on the reaction described above, it is clear that magnesium ribbon and nitrogen gas are combining to form a single product, which is magnesium nitride. Therefore, the reaction is classified as a combination reaction.
**Conclusion**
In conclusion, the burning of magnesium ribbon in an atmosphere of nitrogen gas to form solid magnesium nitride is classified as a combination reaction. This is because two or more substances (magnesium and nitrogen) combine to form a single product (magnesium nitride).
