Question

Write and balance the following equations: Solid Potassium is added an to aqueous fluorine solution to produce aqueous potassium fluoride (5) Solid Aluminum is mixed with molten sulfur and allowed to cool producing a solid aluminum sulfide paste. AL Sulfur trioxide gas is heated producing a sulfur gas mixed with atmospheric elemental oxygen. Magnesium hydride solid is heated giving off hydrogen gas an leaving behind elemental magnesium metal. Elemental iron is added to an aqueous solution of chloric acid which produces an aqueous solution of iron (III) chlorate and giving off hydrogen gas.

Answer 1

Balanced chemical equation. акт , аке 2 (ão) (aq) Here 2 mol of potassium reacts with 1 more of a to produce 2 mole of potassium fluoride. Type of reaction - Synthesis @ QAL+ 3S ALS3 (s) caq) (s) To balance AlzS3 we need to add 2 in front of AL , and 3 in front of s. Type of reaction synthesis. » 2503 > 25+302 To balance sulfur we add 2 in front of Soz and 2 in front of s. Now to balance the ₂ we add 3 in front of it. So overall there are 6 Oxygen atom on both sides. Type of reaction » combustion.

4 Mg H₂ mg + H₂ This nachon is already balanced. There is I mg atom on both sides, and 2 hydrogen (H) alom on both sides. Type of reaction de composition , 5) Fe + 2HClO3 = Fe (ClO3)₂ +H2 (s) can cau) (9) e is balanced. To balance Hydrogen atoms and ce alons and oxygen atoms we add 2 in front of HCO3 The rest are balanced. Type of reaction - Single replacement
