3Mn + N2 ----> Mn3N2 its actually 3mg+N2(arrow) Mg3N2
Mg+ 2HNO3-->Mg(NO3)2 + H2 Products are Magnesium nitrate and Hydrogen gas.
3 Mg + N2 = Mg3N2
a coefficient is the number that falls before the chemical formula.so,in 3Mg N2 - Mg3N2 there are 3 coefficients in that chemical equation. These are present on the reactants side.
Magnesium nitride (Mg3N2) is formed by the reaction of magnesium metal (Mg) with nitrogen gas (N2).

3 MgCl2 + N2 = Mg3N2 + 3 Cl2
Magnesium nitride (Mg3N2) is formed by the reaction of magnesium metal (Mg) with nitrogen gas (N2).
There is no compound with the formula Mg3NO2. There is one with the formula Mg3N2, which is magnesium nitride. Magnesium nitride is an inorganic yellow-green powder.
The chemical formula for magnesium nitride is Mg3N2. There are two reactions in which Mg3N2 can be prepared which are represented by the following equations:3Mg+N2+heat (800 C)---> Mg3N23Mg+2NH3+heat (700 C)---> Mg3N2 + 3H2Source: https://en.wikipedia.org/wiki/Magnesium_nitride
Balanced equation first. 3Mg + N2 -> Mg3N2 55.3 grams Mg (1 mole Mg/24.31 grams)(1 mole Mg3N2/3 mole Mg)(100.95 grams/1 mole Mg3N2) = 76.5 grams Mg3N2 made ===================
Magnesium + Nitrogen ----> Magnesium Nitride3 Mg + N2 ----> Mg3N2
Equation: 3Mg + N2 → Mg3N2 3mol Mg combines with 1mol N2. Molar mass N2 = 28.014g/mol 1.86g N2 = 1.86/28.014 = 0.0664mol N2 This will require 0.0664*3 = 0.1992mol Mg Molar mass Mg = 24.305g/mol 0.1992mol Mg = 24.305*0.1992 = 4.84g Mg required.
