Cr2(SO4)3+ H2SO4+KMnO4反应
配平K2Cr2O7+KI+H2SO4---K2SO4+I2+Cr2(SO4)3+H2O
K2Cr2O7+ H2C2O4+ H2SO4 — K2SO4+ Cr2(SO4)3+ CO2+ H2O
配平 k2cr2o7 + ki + h2so4---k2so4+ cr2(so4)3+ i2+ h2o
K2Cr2O7+H2SO4+K2SO3=K2SO4+Cr2(SO4)3+H2O
K2Cr2O7 + C2H5OH + H2SO4→ ______+ Cr2(SO4)3+ CO2+ H2O
C+K2Cr2O7+H2SO4 ------ CO2+Cr2(SO4)3+K2SO4+H2O 配平
H2O2+K2Cr2O7+H2SO4 =Cr2(SO4)3+K2SO4+O2+H2O
氧化还原反应类型3C+2(K2Cr2O7)+8H2so4=2K2So4+3Co2+2Cr2(So4)3+8H2o若反应中
2CrO3+3C2H5OH+3H2SO4=Cr2(SO4)3+3CH3CHO+6H2O 1mol氧化剂完全反应得到多少m
K2Cr2O7+H2C2O7+H2SO4-----K2SO4+Cr2(SO4)3+CO2+H2O求高手配平...小弟拜谢
C+K2Cr2O7+H2SO4=CO2+K2SO4+Cr2(SO4)3+H2O怎么配平?
化学方程式配平K2Cr2O7+C+H2SO4→Cr2(SO4)3+K2SO4+CO2+H2O
