Answer 1

Объяснение:

2Mg+O2=2MgO

BaCO3=BaO+CO2

Fe+2HCl=FeCl2+H2

2CO+O2=2CO2

2P+3S=P2S3

SiO2+2Mg=Si+2MgO

2KBr+Cl2=2KCl+Br2

3Ca+N2=Ca3N2

BaSO4+Mg(OH)2 реакция не пойдёт

H2+Cl2=2HCl

Answer 2

Ответ:

1)2 Mg + O2 = 2MgO

2) BaCO3 = BaO + CO2

3) Fe + 2HCl = FeCl2 + H2

4) 2CO + O2 =2 CO2

5)2 P + 3S = P2S3

6) SiO2 +2 Mg = Si + 2MgO

7) 2KBr + Cl2 =2 KCl + Br2

8) 3Ca + N2 = Ca3N2

9) BaSO4 + Mg(OH)2=  Ba(OH)2+ MgSO4

10) Н2 + Cl2 =2HCl

Answer 3

Here are the balanced chemical equations for the given reactions:

1. 2Mg + O2 = 2MgO
2. BaCO3 = BaO + CO2
3. 3Fe + 6HCl = 2FeCl3 + 3H2
4. 2CO + O2 = 2CO2
5. 4P + 3S8 = P2S3 (Note: Phosphorus reacts with sulfur to form P2S3)
6. SiO2 + 2Mg = 2MgO + Si (Note: The reaction between SiO2 and Mg does not have a specific product, but it forms magnesium silicate)
7. 2KBr + Cl2 = 2KCl + Br2
8. 3Ca + N2 = Ca3N2
9. BaSO4 + 2Mg(OH)2 = Ba(OH)2 + MgSO4 (Note: The reaction forms barium hydroxide and magnesium sulfate)
10. H2 + Cl2 = 2HCl
