Question

CaO+HCl = CaCl2+H2O P+O2=P2O5 Zn+HCl=ZnCl2+H2 SiH4+O2=SiO2+H2O Na+HOH=NaOH+H2 Al2O3+H2=Al+H2O Fe(OH)3=Fe2O3+H2O KI+Br2=KBr+I2 ZnS+O2=ZnO+SO2 CuCl2+KOH=Cu(OH)2+KCl нужно уравнять

Answer 1

1)CaO+2HCl=CaCl2+H2O

2)4P+5O2=2P2O5

3)Zn+2HCl=ZnCl2+H2↑

4)SiH4+2O2=SiO2+2H2O

5)2Na+2H2O=2NaOH+H2↑

6)Al2O3+3H2=2Al+3H2O

7)2Fe(OH)3=Fe2O3+3H2O

8)2Kl+Br2=2KBr+l2

9)2ZnS+3O2=2ZnO+2SO2

10)CuCl2=2KOH=Cu(OH)2+2KCl
