+2 for each Mg, -3 for each N
The oxidation number of Mg in Mg3N2 is +2. Each N has an oxidation number of -3, so for the compound to be neutral, the magnesium atoms must have an oxidation number of +2.
+2 for Mg
-3 for N
-3
The compound formed between Mg and N is magnesium nitride, with the chemical formula Mg3N2.
3 Mg + N2 = Mg3N2
Mg+ 2HNO3-->Mg(NO3)2 + H2 Products are Magnesium nitrate and Hydrogen gas.
3Mn + N2 ----> Mn3N2 its actually 3mg+N2(arrow) Mg3N2
The oxidation number of Mg in MgO is +2, while the oxidation number of O is -2. The sum of oxidation numbers in a compound should equal zero.

Mg3N2 forms in insufficient air because magnesium reacts with nitrogen gas to form magnesium nitride. When there is not enough oxygen present, magnesium is more likely to react with nitrogen to form Mg3N2 rather than magnesium oxide (MgO).
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 ===================
The oxidation number of Mg in MgO is +2, while the oxidation number of O is -2. The sum of oxidation numbers in a compound should equal zero.
+2
The oxidation numbers for the atoms in magnesium oxide are: Mg+2 and O-2.
The oxidation number for Mg, or Magnesium is Mg+2. Magnesium is in the second family, which means is it will lose 2 electrons to be stable. Losing those two electrons will make it positive.
The O in oxides always has oxidation number -2 (except for in peroxides where it is -1). Since the overall species has oxidation number 0, Mg must also have oxidation number +2.
To calculate the mass of magnesium needed to produce 1.19 grams of magnesium nitride, you need to consider the stoichiometry of the reaction. The molar mass of Mg3N2 (magnesium nitride) is 100.93 g/mol. From the balanced equation, 6 moles of magnesium is needed to produce 1 mole of magnesium nitride. Therefore, you can use the molar mass of magnesium and molar ratio to determine the mass needed.
