Discussion

19.	GIVE REASON 1) Liquids can flow, 2) Burning of paper is a chemical change. 3) When magnesium is burnt in the air, there is an increase in mass after the reaction. 4) When sodium chloride is added to water and stirred well, a solution is formed, however, there's no increase in the level of water. 5) Sublimation method can be used to separate sodium chloride and ammonium chloride.
Answer» Hi your answer Explanation:1) Liquid don't have a definite SHAPE, and they can flow because the particles are still packed close together whereas the liquid can't easily be compressed and keep the same volume. 2) It's a chemical change because when paper is burned, oxygen from the air combines with the carbon and hydrogen in the paper (as paper is an organic material, obtained from WOODS), turning some of it into carbon dioxide and water. And energy is released into the SURROUNDING as heat.3) Oxygen and magnesium combine in a chemical reaction to form this compound. After it BURNS, it forms a white powder of the magnesium oxide. Magnesium GIVES up two electrons to oxygen atoms to form this powdery product.
