在25℃、1.01×105Pa下,将22gCO2通入到750mL1.0mol/L的NaOH溶液中充分反应,放出xkJ热量。已知该条件下,1mol CO2通入到2L1.0mol/LNaOH溶液中充分反应,放出y kJ的热量.则CO2与NaOH溶液反应生成NaHCO3的热化学方程式正确为
A.CO2(g)+NaOH(aq)=NaHCO3(aq)△H=-(2y-x)kJ/mol |
B.CO2(g)+NaOH(aq)=NaHCO3(aq)△H=-(4x-y)kJ/mol |
C.CO2(g)+NaOH(aq)=NaHCO3(aq)△H=-(2x-y)kJ/mol |
D.CO2(g)+NaOH(aq)=2NaHCO3(aq)△H=-(8x-2y)kJ/mol |
