Giant covalent bonds Study guides, Class notes & Summaries

Edexcel iGCSE Chemistry, question and answer with rated solution Experiment for Diffusion? 1) HCl placed at one end of the test tube, ammonia solution at the other. 2) Where they meet, a ring of Ammonium Chloride appears. 3) The diagram shows that the ammonia is closer to the ring, showing that ammonia must have travelled faster, showing it's a lighter gas. Experiment for Dilution? 1) Put a coloured substance in a solvent e.g food colouring in water. 2) Over the time, the colour le...
