A．等物质的量的硫蒸气和硫固体分别完全燃烧，后者放出的热量少 |
|
B．由单质\(\rm{A}\)转化为单质\(\rm{B}\)时\(\rm{ΔH=+119 kJ·mol^{-1}}\)可知单质\(\rm{B}\)比单质\(\rm{A}\)稳定 |
|
C．稀溶液中：\(\rm{H^{+}}\)\(\rm{(aq)+OH}\)\(\rm{{\,\!}^{-}}\)\(\rm{(aq)═H}\)\(\rm{{\,\!}_{2}}\)\(\rm{O(l)}\) \(\rm{ΔH=-57.3 kJ·mol}\)\(\rm{{\,\!}^{-1}}\)，若将含\(\rm{0.5 mol H}\)\(\rm{{\,\!}_{2}}\)\(\rm{SO}\)\(\rm{{\,\!}_{4}}\)的浓硫酸与含\(\rm{1 mol NaOH}\)的溶液混合，放出的热量大于\(\rm{57.3 kJ}\) |
|
D．在\(\rm{101 kPa}\)时，\(\rm{H_{2}}\)燃烧的热化学方程式为\(\rm{2H}\)\(\rm{{\,\!}_{2}}\)\(\rm{(g)+O}\)\(\rm{{\,\!}_{2}}\)\(\rm{(g)═2H}\)\(\rm{{\,\!}_{2}}\)\(\rm{O(l)}\) \(\rm{ΔH=-571.6 kJ·mol}\)\(\rm{{\,\!}^{-1}}\)，则\(\rm{H}\)\(\rm{{\,\!}_{2}}\)在\(\rm{101 kPa}\)时的燃烧热为\(\rm{571.6 kJ·mol}\)\(\rm{{\,\!}^{-1}}\) |
