Question

сбалансировать уравнения:
1)Zn Cl2 +KOH =
2)CoF2 +H2S =
3)CuBr3+NaOH =
4)AgNo3 +HCl=
5)CaCl2+H2SO3 =
6)FeCl2+Na2S=
7)SnCl2+K2S=

Answer 1

1)Zn Cl2 +2KOH =Zn(OH)2+2KCl
2)CoF2 +H2S =CoS+2HF
3)CuBr3+3NaOH =Cu(OH)2+3NaBr
4)AgNo3 +HCl=AgCl+HNO3
5)CaCl2+H2SO3 =CaSO3+2HCl
6)FeCl2+Na2S=FeS+2NaCl
7)SnCl2+K2S=SnS+2KCl
