Memorize chem reactions

Notes

• Synthesis Reactions: - Metal oxide + water → metallic hydroxide - Metal O + H₂O → metal(OH) - Nonmetallic oxide + water → acid - Nonmetal + H₂O → H nonmetal - Metal + nonmetal → salt - 2Na(s) + Cl₂(g) → 2NaCl(s) - N₂ + 3H₂ → 2NH₃ - NH₃(g) + H₂O → NH₄OH • Decomposition Reactions: - Metallic carbonates Δ → metallic oxide + CO₂(g) + H₂O - CaCO₃ Δ → CaO + CO₂ - Metallic hydroxides Δ → metallic oxide + H₂O - Ca(OH)₂ Δ → CaO + H₂O - Metallic chlorates Δ → metallic chlorides + O₂ - 2KClO₃ Δ → 2KCl + O₂ - Acid decomposition Δ → nonmetallic oxides + water - H₂SO₄ → SO₃ + H₂O • Additional Notes: - Double replacement reactions will never be redox reactions. - Oxygen in a peroxide (H₂O₂) has an oxidation state of -1. - Hydrogen has an oxidation state of -1 when combined with a metal. • Exceptions and Solubility: - Insoluble substances are considered solid. - None (substances) are soluble and are aqueous in solution.
