Question

H2S + O2 → Al + O2 → 6) CH4 + O2 T) Mg + 02 → e) C2H4 + 02 → K2O + H2O →

Answer 1

Ответ:

Объяснение:

2H2S + 3O2 = 2SO2 + 2H2O

4Al + 3O2 = 2Al2O3

CH4 + 2O2 = CO2 + 2H2O

2Mg + O2 = 2MgO

C2H4 + 3O2 = 2CO2 + 2H2O

K2O + H2O = 2KOH

Answer 2

Let's balance the chemical equations you provided:

1. H2S + O2 → H2O + SO2 To balance this equation, we need to make sure that the number of atoms of each element is equal on both sides of the equation: H2S + 3O2 → 2H2O + 2SO2

2. Al + O2 → Al2O3 This equation is already balanced.

3. CH4 + O2 → CO2 + H2O To balance this equation, we count the number of atoms on each side: CH4 + 2O2 → CO2 + 2H2O

4. Mg + O2 → MgO This equation is already balanced.

5. C2H4 + O2 → CO2 + H2O To balance this equation, we count the number of atoms on each side: C2H4 + 3O2 → 2CO2 + 2H2O

6. K2O + H2O → KOH This equation is already balanced.

I have balanced the chemical equations according to the best of my understanding. If you have any further questions, please let me know!
