Which expression giv -4ilmt(lhxysmoa-) r:st1kxg :,7y qe ;yt+i;h9fi/ut uw3occ8 kka5s the enthalpy change, ΔH, for the production of hydrated copper (II) sulfate from its anhydrous 9hafu3;;tw y/kc 5k ti8+iuo c salt:
A. ΔH$_1$=ΔH$_2$-ΔH
B. ΔH=ΔH$_1$-ΔH$_2$
C. ΔH=ΔH$_1$+ΔH$_2$
D. ΔH$_2$=ΔH$_1$+ΔH
参考答案: B
本题详细解析:
By applying Hess’s law, regardless of the route by which a chemical reaction proceeds, the enthalpy change will always have the same, provided that the initial and final states of the system are identical.
