Here are the chemical formulas for the given compounds: 1. Aluminium Sulphide Step 1: Identify the ions and their charges. Aluminium is in Group 13, forming an Al^3+ ion. Sulphide is from sulfur (Group 16), forming an S^2- ion. Step 2: Balance the charges to form a neutral compound. To balance the +3 charge of Al^3+ and the -2 charge of S^2-, we need 2 aluminium ions and 3 sulphide ions (2 × +3 = +6 and 3 × -2 = -6). The chemical formula is: Al_2S_3 2. Magnesium tetraoxophosphate (V) Step 1: Identify the ions and their charges. Magnesium is in Group 2, forming an Mg^2+ ion. Tetraoxophosphate (V) refers to the phosphate ion, PO_4^3-, where phosphorus has an oxidation state of +5. Step 2: Balance the charges to form a neutral compound. To balance the +2 charge of Mg^2+ and the -3 charge of PO_4^3-, we need 3 magnesium ions and 2 phosphate ions (3 × +2 = +6 and 2 × -3 = -6). The chemical formula is: Mg_3(PO_4)_2 3. Mercury (II) oxide Step 1: Identify the ions and their charges. Mercury (II) indicates the Hg^2+ ion. Oxide is from oxygen (Group 16), forming an O^2- ion. Step 2: Balance the charges to form a neutral compound. The +2 charge of Hg^2+ and the -2 charge of O^2- balance each other in a 1:1 ratio. The chemical formula is: HgO 4. Chromium (III) trioxosulphate (VI) Iron Step 1: Identify the ions and their charges. Chromium (III) indicates the Cr^3+ ion. Trioxosulphate (VI) refers to the sulfate ion, SO_4^2-, where sulfur has an oxidation state of +6. (Note: "trioxo" is likely a typo for "tetraoxo" in this context, as sulfate has 4 oxygen atoms). The word "Iron" at the end is ambiguous in this context. Assuming it is an extraneous word or a typo, we will provide the formula for Chromium (III) sulfate. Step 2: Balance the charges to form a neutral compound. To balance the +3 charge of Cr^3+ and the -2 charge of SO_4^2-, we need 2 chromium ions and 3 sulfate ions (2 × +3 = +6 and 3 × -2 = -6). The chemical formula is: Cr_2(SO_4)_3 5. Potassium tetraoxomanganate (VII) Step 1: Identify the ions and their charges. Potassium is in Group 1, forming a K^+ ion. Tetraoxomanganate (VII) refers to the permanganate ion, MnO_4^-, where manganese has an oxidation state of +7. Step 2: Balance the charges to form a neutral compound. The +1 charge of K^+ and the -1 charge of MnO_4^- balance each other in a 1:1 ratio. The chemical formula is: KMnO_4 Send me the next one 📸
