Question

Решите химичные уровнения:

1)......+O2= SO2

2) Fe+....... = FeS

3)...... +Br2= AeBr3

4)Ca + O2 =.......

5)Fe+.......=Fe2O3

6)Li + O2 =..........

 

Answer 1

 

S+O2=SO2

Fe+S=FeS

AeBr+Br2=AeBr3

2Ca+O2=2CaO

4Fe + 3O2 = 2Fe2O3

4Li + O2 = 2Li2O 

Answer 2

S + O2 = SO2

Fe + S = FeS

2Al + 3Br2 = 2AlBr3

2Ca + O2 = 2CaO

4Fe + 3O2 = 2Fe2O3

4Li + O2 = 2Li2O
