Question

Химия: H2so4+caco7= h2s+cu= h2s+zn= h2s+mgo= h2s+koh= h2s+cu(oh)2= h2s+ba(no)3= h2s+caco7=

dimadi1 · Answer

1)H2SO4+CaCO3=CaSO4+H2O+CO2 2)H2S+Cu=не идет 3)H2S+Zn=ZnS+H2 4)H2S+MgO=MgS+H2O 5)H2S+2KOH=K2S+2H2O 6) H2S+Cu(OH)2=CuS+2H2O 7)H2S+Ba(NO3)2=не идет 8) H2S+CaCO3=CaS+H2O+CO2...

H2so4+caco7= h2s+cu= h2s+zn= h2s+mgo= h2s+koh= h2s+cu(oh)2= h2s+ba(no)3= h2s+caco7=
