Question

СН4 + О2 = Н2S + О2 = Al + O2 =

Answer 1

Ответ:

CH4+2O2=CO2+2H2O

2H2S+3O2=2SO2+2H2O

4Al+3O2=2Al2O3

Answer 2

It seems like you've written a few chemical equations, but they're not balanced correctly. Let's go through them step by step:

1. CH4 + O2 → ? This is the combustion reaction of methane (CH4) with oxygen (O2). The balanced equation is: CH4 + 2O2 → CO2 + 2H2O

2. H2S + O2 → ? This is the reaction of hydrogen sulfide (H2S) with oxygen (O2), but it's not balanced. The balanced equation is: 2H2S + 3O2 → 2H2O + 2SO2

3. Al + O2 → ? This is the reaction of aluminum (Al) with oxygen (O2), and it's also not balanced. The balanced equation is: 4Al + 3O2 → 2Al2O3

So, the balanced chemical equations are:

1. CH4 + 2O2 → CO2 + 2H2O
2. 2H2S + 3O2 → 2H2O + 2SO2
3. 4Al + 3O2 → 2Al2O3
