h2so4=h2o+?
h2so4=h正一和so4负2 h2so4+n个h2o=h2so4.n h2o 的先后顺序意思是浓硫酸加水进行2种变化 即进行电离又进行水合那浓硫酸加水就含有h正一 so4负2 h2so4.n h2o 水没有了?h2so4=h正一和so4负2 h2so4+n
Na2SO4+________= H2SO4 + ______
SO3+H2O=H2SO4的反应中 S O H的化合价前后分别是多少
稀h2so4和baoh2离子咋错了?h+so4+ba+oh=baso4+2h2o
NaOH 与 H2SO4 离子方程式是2OH(-)+2H(+)+SO4(2-)=2H2O+SO4还是OH(-)+H(+)+SO4(2-)=H2O+SO4?是OH(-)+H(+)=H2O还是2OH(-)+2H(+)=2H2O
配平化学方程式:SO2+H2O=H2SO4
h2so4+kmno4+k2so3=k2so4+mnso4+h2o
P4+CuSO4+H2O=Cu3P+H3PO4+H2SO4...
Na2O+H2SO4 =Na2SO4+H2O离子方程式
( )+H2SO4=( )+2H2O
SO4+H2O=H2SO4怎么配平?
FeS2+H2O+O2=FeSO4+H2SO4配平
BaCO3+H2SO4=BaSO4+CO2+H2O
SO3+H2O=H2SO4可逆吗?
赔平P+CUSO4+H2O=CU+H3PO4+H2SO4配平P+CUSO4+H2O=CU+H3PO4+H2SO4
初三化学(1)H2O中H%=?(2)H2SO4中S%=?(3)NH4NO3中N%=?(1)H2O中H%=?(2)H2SO4中S%=?(3)NH4NO3中N%=?
