Hkolnik32 · Answer

SO2+h20=H2SO3

2SO2+2O2 = 2SO3

SO2+2KOH=K2SO3+H2O

SO2+CAO=CaSO3

2H2S+3O2=2H2O+2SO2

H2S+2KOH=2KS+2H2O cредняя соль (H2S+KOH=KHS+H2O кислая соль)

H2S+CU(NO3)2=2HNO3+Cu2S

H2S+MG=MGH2S

2H2SO4+2NAOH=Na2SO4+2H2O

H2SO4+CUO=CuSO4+H2O

H2SO4+BACL2=BaSO4+2HCl

H2SO4+MG=MgSO4+H2 (cnhtkrf ddth[)
