Question
Which of the following reactions represents ΔH(hydration)-
- CuSO4(s)+(aq)→CuSO4(aq);ΔH=–xKJ
- BaCl2(s)+2H2O(
)→BaCl2.2H2O(s);ΔH=–x’KJ
- CuSO4(s)+5H2O()+(aq) →CuSO4.H2O(aq);ΔH=–y’KJ
- None of the above
)→BaCl2.2H2O(s);ΔH=–x’KJ
)+(aq) →CuSO4.H2O(aq);ΔH=–y’KJ
The correct answer is: BaCl2(s)+2H2O()→BaCl2.2H2O(s);ΔH=–x’KJ
