You're on a roll — 7 (a) The valency of the Sulphate radical (SO_4^2-) is -2. 7 (b) The valency of the Hydroxide radical (OH^-) is -1. 7 (c) The valency of the Phosphate radical (PO_4^3-) is -3. 8 (a) The branch of chemistry that deals with the study and manufacture of such minerals (like Ammonium Nitrate fertilizer) is Industrial chemistry. 8 (b) It is important for a chemist to use a consistent chemical formula because it ensures universal understanding and clear communication among scientists worldwide. A consistent formula uniquely identifies a substance, preventing ambiguity and allowing for accurate replication of experiments, safe handling, and reliable trade of chemical products across different regions and languages. 9 (a) The common name given to elements in Group 18 (VIII) of the periodic table is Noble gases. 9 (b) One practical use of these gases in the transport industry is using Helium to inflate balloons and airships. Helium is chosen because it is much lighter than air and non-flammable, making it a safe and effective lifting gas for lighter-than-air craft. Almost done! Send the last one.
