3. How to balance H₂SO₄ + Mg₃N₂?

The H, S, O, Mg, and N atoms must all be present in equal amounts on each side of the equation for H₂SO₄ and Mg₃N₂ reaction to being balanced.

• First, we label each of the four molecules—A, B, C, and D—because there are four. The reply looks like this:
• A H₂SO₄ + B Mg₃N₂ = C MgSO₄ + D (NH₄)₂SO₄
• The number of coefficients specified as alphabets in the reactants and products is now determined using the proper values.

Element	Reaction side	Product side

Sulfur	1A+0B	1C+1D
Oxygen	4A+0B	4C +4D
Magnesium	0A +3B	1C +0D
Nitrogen	0A+2B	0C+2D

• The coefficient and variables required to balance the equation are obtained using the Gaussian elimination approach in Step 3.
• A= 4(H₂SO₄), B= 1(Mg₃N₂), C= 3(MgSO₄), D= 1 (NH₄)₂SO₄
• The reactant and product sides now contain an equal number of each element.

Element	Reaction side	Product side
Hydrogen	8	8
Sulfur	4	4
Oxygen	16	16
Magnesium	3	3
Nitrogen	2	2

• The reaction between H₂SO₄ and Mg₃N₂ has a balanced equation in step four, which is

8. H₂SO₄ + Mg₃N₂ reaction enthalpy

The reaction enthalpy of H₂SO₄ + Mg₃N₂ is -2198.1 KJ/mol

Compound	Moles	Enthalpy of formation, ΔH0f (KJ/mol)
H2SO4	4	-814
Mg3N2	1	457.2
MgSO4	3	-1272
(NH4)2SO4	1	-1180.9

• The standard enthalpy of a reaction can be calculated using the formula below:
• The formula is, ΔH⁰_{f (reaction)} = ΣΔH⁰_{f (product)} – ΣΔH⁰_{f (reactants)} 
• Thus, enthalpy change = [3*(-1272) + 1*(-1180.9)] – [4*(-814) + 1*(457.2)] KJ/mol = -2198.1 KJ/mol

 9. Is H₂SO₄ + Mg₃N₂ a buffer solution?

H₂SO₄ + Mg₃N₂ reaction won’t produce a buffer solution since H₂SO₄ is a strong acid.

10. Is H₂SO₄ + Mg₃N₂ a complete reaction?

H₂SO₄ + Mg₃N₂ is a complete reaction, as it indicates the formation of magnesium sulfate and ammonium tetraoxosulfate(VI), two stable molecules.

11. Is H₂SO₄ + Mg₃N₂ an exothermic or endothermic reaction?
