Consider these reactions, where m represents a generic metal.
a. 2 m ( s ) + 6 hcl ( aq ) ⟶ 2 mcl 3 ( aq ) + 3 h 2 ( g ) δ h 1 = − 805.0 k j
b. hcl ( g ) ⟶ hcl ( aq ) δ h 2 = − 74.8 k j
c. h 2 ( g ) + cl 2 ( g ) ⟶ 2 hcl ( g ) δ h 3 = − 1845.0 k j
d. mcl 3 ( s ) ⟶ mcl 3 ( aq ) δ h 4 = − 484.0 k j
use the given information to determine the enthalpy of the reaction
