Nitrogen leaves the top of the column as a gas. Purity levels required by nitrogen users are becoming increasingly stringent and it may be liquefied again and redistilled. It is unusual for the nitrogen to have an oxygen content of more than 10 ppm and impurities contained in nitrogen for the electronics industry are measured in parts per billion.
38. Chlorine gas can be produced by heating calcium hypochlorite, Ca(OCl)2, in dilute hydrochloric acid. Ca(OCl) 2(s) + 2HCl (aq) → Ca(OH) 2(aq) + 2Cl 2(g) Calculate the mass of calcium hypochlorite that would be needed to produce 0·096 litres of chlorine–1.)
Molecular nitrogen (\(N_2\)) is not reactive at standard temperature and pressure and is a colorless and odorless gas. Figure \(\PageIndex{1}\) : A Bohr diagram of the nitrogen atom. Nitrogen is a non-metal element that occurs most abundantly in the atmosphere, nitrogen gas (N 2 ) comprises 78.1% of the volume of the Earth’s air.
Most metal carbonates you will come across will break down on strong heating (thermal decomposition) to give a metal oxide and carbon dioxide gas. When limestone is heated in a kiln at over 825-900 o C, it breaks down into quicklime (calcium oxide) and carbon dioxide.
