Experiment for Diffusion? - correct answer 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? - correct answer 1) Put a coloured substance in a solvent e.g f...

SAMPLE CHEMISTRY PLACEMENT EXAM QUESTIONS WITH COMPLETE SOLUTIONS 100% 2023/2024 Answer: Oxygen Aluminum forms a +3 ion. In order for the formula unit Al₂X₃ to be electrically neutral, the element X must form a -2 ion. Nonmetals in the oxygen column do this. Of these elements, only oxygen is a diatomic gas. Aluminum reacts with element X to form a compound with the formula A₂X₃. Element X exists as diatomic molecules, X₂, in the gaseous state at normal temperature and pressure. Elem...
