The product of the chemical reaction must be AlN-Aluminum nitride. So the balanced reaction is N2(g)+Al(s)→ΔAlN(s)
An equation for a chemical reaction is said to be balanced if both the reactants and the products have the same number of atoms and the total charge for each component of the reaction. In other words, both sides of the chemical reaction have an equal balance of mass and charge. The equation must be balanced so that each type of atom appears in equal amounts on both the left and right sides of the arrow. This is accomplished by altering the compounds' coefficients (numbers placed in front of compound formulas). Balancing for mass produces the same numbers and kinds of atoms on both sides of the equation in a chemical reaction.
