Chem 1B Chemical Reactions Homework
Write balanced equation(s) predicting potential products if any between the following reagents. Show the driving force for reaction. If no reaction, show specifically why. For metathesis show the CE, IE, and NIE; for all others show NIE. Assume species are under standard thermodynamic conditions.
1. calcium carbonate and sulfuric acid
2. solid potassium sulfide and sodium chloride solution
3. iron(III) sulfate solution and aqueous ammonia
4. chlorine is bubbled in sodium iodide solution
5. sodium is carefully added aqueous potassium bromide
6. sodium hydrogen carbonate and lithium monohydrogen phosphate
7. sodium oxide is carefully stirred into water
8. solid potassium chlorate decomposes at high temperature
9. copper is placed in aqueous bromine
10. iron(III) chloride and potassium iodide solutions are mixed
11. silver is placed in nitric acid
12. gold is placed in hydrochloric acid
13. potassium permanganate and hydrochloric acid
14. iron(II) sulfate and silver nitrate solutions
15. aqueous hydrogen peroxide and nitric acid
16. ethanol + potassium permanganate + hydrochloric acid
17. HS⁻ + HSO₃⁻ → S₂O₃²⁻ (acidic solution)
18. As₂S₃ + NO₃⁻ → H₃AsO₄ + S + NO (acidic)
19. CrI₃(s) + H₂O₂ → CrO₄²⁻ + IO₄⁻ (basic solution)
20. CH₄(g) + NH₃(g) + O₂(g) → HCN(g) + H₂O(g)
