How nitrogen is prepared in the laboratory?
Dinitrogen is prepared in the laboratory by heating a solution an equivalent amount of sodium nitrite and ammonium chloride when ammonium nitrite and sodium chloride are formed. Ammonium nitrite then decomposes to nitrogen and water. NH4Cl + NaNO2 → NH4NO2 + NaCl NH4NO2 → N2 + 2H2O
What happens when calcium phosphide is treated with water?
One mole of calcium phosphide reacts with six moles of water to form two moles of phosphine and three moles of calcium hydroxide. Ca3P2 + 6H2O → 3Ca(OH)2 + 2PH3
What happens when magnesium nitride is treated with water?
One mole of magnesium nitride reacts with six moles of water to form two moles of ammonia and three moles of magnesium hydroxide. Mg3N2 + 6H2O → 3Mg(OH)2 + 2NH3
What happens when phosphorous acid is heated?
Four moles of phosphorous acid decompose to form three moles of phosphoric acid and one mole of phosphine. 4H3PO3 → 3H3PO4 + PH3
What happen when nitrous acid is heated?
Three moles of nitrous acid decompose to form one mole of nitric acid, two moles of nitric oxide and one mole of water. 3HNO2 → HNO3 + 2NO + H2O

What is Henry’s law? Henry’s law describes the relationship between the pressure of a gas and its solubility in a liquid. It states that the solubility of a gas in a liquid is directly proportional to the partial pressure of that gas above the liquid. Mathematically, it can be represented as: C=k⋅P Where: C is…
