A chemist investigates the synthesis of magnesium nitride by heating highly purified magnesium ribbon in a stream of pure nitrogen gas, N2\text{N}_2N2.
In a crucible, 1.458 g of magnesium reacts completely and exactly with 0.560 g of nitrogen gas.
[Relative atomic masses: Mg=24.3\text{Mg} = 24.3Mg=24.3, N=14.0\text{N} = 14.0N=14.0]
Determine, using this information, the balanced chemical equation for the reaction between magnesium and nitrogen gas to produce magnesium nitride.
