題目列表(包括答案和解析)
(2) 2Ag(s)+1/2 O2(g)== Ag2O(s),ΔH=-31.0kJ/mol
則Zn(s)+ Ag2O(s)== ZnO(s)+ 2Ag(s)的ΔH等于
A.-317.3kJ/mol B.-379.3kJ/mol C.-332.8 kJ/mol D.317.3 kJ/mol
已知:(1)Zn(s)+1/2O2(g) = ZnO(s);ΔH =-348.3 kJ/mol;(2)2Ag(s)+1/2O2(g) = Ag2O(s);ΔH =-31.0 kJ/mol,則Zn(s)+Ag2O(s) = ZnO(s)+2Ag(s)的?ΔH等于( )
A.-317.3 kJ/mol | B.-379.3 kJ/mol | C.-332.8 kJ/mol | D.317.3 kJ/mol |
已知: (1)Zn(s)+1/2O2(g) = ZnO(s);ΔH =-348.3 kJ/mol;(2)2Ag(s)+1/2O2(g) = Ag2O(s);ΔH =-31.0 kJ/mol,則Zn(s)+Ag2O(s) = ZnO(s)+2Ag(s)的ΔH等于( )
A.-317.3 kJ/mol B.-379.3 kJ/mol C.-332.8 kJ/mol D.317.3 kJ/mol
已知:(1)Zn(s)+1/2O2(g)=ZnO(s),ΔH=-348.3kJ/mol(2)2Ag(s)+1/2O2(g)=Ag2O(s),ΔH=-31.0kJ/mol 則Zn(s)+Ag2O(s)=ZnO(s)+2Ag(s)的ΔH等于
A.-317.3kJ/mol B.-379.3kJ/mol C.-332.8kJ/mol D. +317.3 kJ/mol
已知:(1)Zn(s)+1/2O2(g)=ZnO(s),ΔH=-348.3kJ/mol
(2)2Ag(s)+1/2O2(g)=Ag2O(s),ΔH=-31.0kJ/mol
則Zn(s)+Ag2O(s)=ZnO(s)+2Ag(s)的ΔH等于( )
A -317.3kJ/mol B -379.3kJ/mol
