Preparation of nitrogen Nitrogen is found in both free and combined states. It occupies 78.07% by volume. Nitrogen can be prepared: By heating copper in air: Firstly, air is passed through lime water and then concentrated sulphuric acid to make the air free from carbon dioxide and moistures respectively. The air contains only nitrogen and … Read more
Non Metals As far as Elements are concerned, a nonmetal is simply an element that does not display the properties of a Metal. It is not defined by what it is, but by what it is not. It doesn’t look metallic, can’t be drawn into a wire or pounded into shape or bent, doesn’t conduct … Read more
