Mixtures

Mixtures

1. compounds

   • water is made up of hydrogen atoms and oxygen atoms joined together. There re two atoms of hydrogen for every atom of oxygen. this is true for every molecule of water.

2. Chromotography

   • Chromotography is a way of separating mixtures. You can see how it works by using coloured inks. First a spot of the micture is placed near the bottem of some filter paper and allowed to dry. then the bottem of the filter paper is dipped into water that will be able to dissolve the ink, the liquid slowly rises up and carries some of the ink with it. Because the different colours move at different speads they will eventually be spaced out along the path of a solvent
