Question

Consider these reactions, where M represents a generic metal. 2 M ( s ) + 6 HCl ( aq ) ⟶ 2 MCl 3 ( aq ) + 3 H 2 ( g ) Δ H 1 = − 870.0 k J HCl ( g ) ⟶ HCl ( aq ) Δ H 2 = − 74.8 k J H 2 ( g ) + Cl 2 ( g ) ⟶ 2 HCl ( g ) Δ H 3 = − 1845.0 k J MCl 3 ( s ) ⟶ MCl 3 ( aq ) Δ H 4 = − 300.0 k J Use the given information to determine the enthalpy of the reaction 2 M ( s ) + 3 Cl 2 ( g ) ⟶ 2 MCl 3 ( s )
