Answer 2

Equations for the Given Reactions:

1) Sodium Nitrate Decomposition: - Equation: 2 NaNO3 → 2 NaNO2 + O2 [[1]] 2) Lithium Nitride Formation: - Equation: 6 Li + N2 → 2 Li3N [[2]] 3) Ammonia Combustion: - Equation: 4 NH3 + 5 O2 → 4 N2 + 6 H2O [[3]] 4) Barium Sulfate and Sodium Chloride Precipitation: - Equation: BaCl2 + Na2SO4 → BaSO4 + 2 NaCl [[4]] 5) Phosphoric Acid and Sodium Hydroxide Neutralization: - Equation: 3 H3PO4 + 3 NaOH → Na3PO4 + 3 H2O [[5]]

Please note that the coefficients in the equations are balanced to ensure that the number of atoms of each element is the same on both sides of the equation.
