Consider these reactions, where M represents a generic metal. 1. 2 M(s) + 6 HCl(aq) → 2 MCl, (aq) + 3 H, (g) AH1 = -582.0 kJ 2. HCl(g) → HCl(aq) AH2 = -74.8 kJ 3. H, (g) + Cl, (g) → 2 HCI(g) AH3 = -1845.0 kJ 4. MCI, (s) → MCI, (aq) AH4 = -434.0 kJ Use the given information to determine the enthalpy of the reaction 2 M(s) + 3 Cl, (g) → 2 MCI, (s) ΔΗ- kJ

The reaction between HCl and NaOH is represented below. When equal volumes of 1.00 M NaOH and 1.00 M HCl are mixed, 57.1 kJ of heat is released. What would A H be if 2.00 M HCI and 2.00 M NaOH is used instead of 1.00 M? HCl(aq) + NaOH(aq) → NaCl(aq) + H₂O(l) AH = -57.1 kJ/mol... (A) - 28.6 kJ B-85.7 kJ (c) -57.1 kJ D - 114 kJ

Consider these reactions, where M represents a generic metal. 1. 2 M(s) + 6 HC1(aq) → 2 MCl,(aq) + 3 H,(g) ΔΗ = -589.0 kJ 2. HCI(g) → HCI(aq) AH2 = -74.8 kJ 3. H,(g) + Cl,(g) –→ 2 HCI(g) AH3 = -1845.0 kJ 4. MCI,(s) → MCl,(aq) AH4 = -262.0 kJ Use the given information to determine the enthalpy of the reaction 2 M(s) + 3 Cl,(g) → 2 MCl,(s) ΔΗ- kJ
