Answer 1

Ответ:

Mg + О2 = 2MgO

S + О2 = SO2

Zn + О2 = 2ZnO

P + О2 = P2O5

C2H2 + О2 = 2CO2 + H2O

Ca + О2 = 2CaO

Si + О2 = SiO2

H2S + О2 = SO2 + H2O

Answer 2

2 Mg + O2 → 2 MgO

S + O2 → SO2

2 Zn + O2 → 2 ZnO

4 P + 5 O2 → 2 P2O5

2 C2H2 + 5 O2 → 2 H2O+ 4 CO2

2 Ca + O2 → 2 CaO

Si + O2 → SiO2

2 H2S + 3 O2 → 2 H2O + 2 SO2

Answer 3

Balancing Chemical Equations:

To balance the chemical equations provided, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Here are the balanced equations for the given reactions:

1. Mg + O2 = MgO - Magnesium (Mg) reacts with oxygen (O2) to form magnesium oxide (MgO). - The balanced equation is: 2Mg + O2 = 2MgO [[1]].

2. S + O2 = SO2 - Sulfur (S) reacts with oxygen (O2) to form sulfur dioxide (SO2). - The balanced equation is: 2S + 3O2 = 2SO2 [[2]].

3. Zn + O2 = ZnO - Zinc (Zn) reacts with oxygen (O2) to form zinc oxide (ZnO). - The balanced equation is: 2Zn + O2 = 2ZnO [[3]].

4. P + O2 = P2O5 - Phosphorus (P) reacts with oxygen (O2) to form diphosphorus pentoxide (P2O5). - The balanced equation is: 4P + 5O2 = 2P2O5 [[4]].

5. C2H2 + O2 = CO2 + H2O - Acetylene (C2H2) reacts with oxygen (O2) to form carbon dioxide (CO2) and water (H2O). - The balanced equation is: 2C2H2 + 5O2 = 4CO2 + 2H2O [[5]].

6. Ca + O2 = CaO - Calcium (Ca) reacts with oxygen (O2) to form calcium oxide (CaO). - The balanced equation is: 2Ca + O2 = 2CaO [[6]].

7. Si + O2 = SiO2 - Silicon (Si) reacts with oxygen (O2) to form silicon dioxide (SiO2). - The balanced equation is: Si + O2 = SiO2 [[7]].

8. H2S + O2 = SO2 + H2O - Hydrogen sulfide (H2S) reacts with oxygen (O2) to form sulfur dioxide (SO2) and water (H2O). - The balanced equation is: 2H2S + 3O2 = 2SO2 + 2H2O [[8]].
