举一反三
- 下列反应中哪个是表示ΔH=ΔfHmθ(AgBr , s)的反应( ) A: Ag(aq) + Br(aq) =AgBr(s) B: 2Ag(s) + Br2(g) =2AgBr(s) C: Ag(s) + Br2(l) =1/2 AgBr(s) D: Ag(s) + 1/2 Br2(l) =AgBr(s)
- 下列反应中哪个是表示ΔrHmӨ = ΔfHmӨ(AgBr, s)的反应 A: 2Ag(s) + Br2(g) =2AgBr(s) B: Ag(s) + 1/2Br2(l) = AgBr(s) C: Ag(s) +1/2Br2(g) = AgBr(s) D: Ag(aq) + Br(aq) =AgBr(s)
- 下列方程式中,能正确表示AgBr(s)的△fHm⊖的是 A: Ag(s)+1/2Br 2 (g)→ AgBr(s) B: Ag(s)+1/2Br 2 (l)→AgBr(s) C: 2Ag(s)+Br 2 (l)→ 2AgBr(s) D: Ag + (aq)+Br-(aq)→ AgBr(s)
- 在298K时,下列反应的△r H mθ 等于AgBr(s) △fHmθ 的为:() A: Ag +(aq) + Br- (aq) = AgBr (s) B: 2Ag(s) + Br2(l) = 2 AgBr (s) C: Ag(s) + ½ Br2(g) = AgBr (s) D: Ag(s) + ½ Br2(l) = AgBr (s)
- 下列反应中的[img=66x21]1803d7dfd7dade0.png[/img]等于AgBr(s)的[img=67x25]1803d7dfe08d019.png[/img]的是( ) 未知类型:{'options': ['Ag(s) + ½Br(l) == AgBr(s)', 'Ag[img=11x21]1803d7dfe86c019.png[/img](aq) + Br[img=11x21]1803d7dff0aee91.png[/img](aq) == AgBr(s)', '2Ag(s) + Br(g) == 2AgBr(s)', 'Ag(s) +½Br(g) == AgBr(s)'], 'type': 102}
