Question

Химия: 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

den2424denoztwre · Answer

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
