配平K2Cr207+K2SO3+H2SO4---Cr2(SO4)3+K2SO4+H20,Au2O3+Na2S2+NaOH
K2Cr2O7+H2SO4+K2SO3=K2SO4+Cr2(SO4)3+H2O
配平K2Cr2O7+KI+H2SO4---K2SO4+I2+Cr2(SO4)3+H2O
配平 k2cr2o7 + ki + h2so4---k2so4+ cr2(so4)3+ i2+ h2o
C+K2Cr2O7+H2SO4 ------ CO2+Cr2(SO4)3+K2SO4+H2O 配平
K2Cr2O7+ H2C2O4+ H2SO4 — K2SO4+ Cr2(SO4)3+ CO2+ H2O
H2O2+K2Cr2O7+H2SO4 =Cr2(SO4)3+K2SO4+O2+H2O
配平方程式,请写出具体步骤:H2O2+Cr2(SO4)3+KOH-K2CrO4+K2SO4+H20
K2Cr2O7+H2C2O7+H2SO4-----K2SO4+Cr2(SO4)3+CO2+H2O求高手配平...小弟拜谢
