Answer 1

Ответ:

1) 2H²+O²= 2H²O

2) Mg²+O²= 2MgO

3)N²+O²= 2NO

4) NO+O²= NO²

5) 4NO²+2H²O+O²=4HNO³

6) 2As+3O²= 2AsO³

7)CH⁴+O²= CO²+2H²O

Answer 2

It seems like you've listed a series of chemical reactions. I'll provide you with the balanced chemical equations for each of them:

1. H2 + O2 -> H2O (Balanced equation for the combustion of hydrogen)
2. Mg + O2 -> 2MgO (Balanced equation for the combustion of magnesium)
3. N2 + O2 -> 2NO (Balanced equation for the formation of nitrogen monoxide)
4. 2NO + O2 -> 2NO2 (Balanced equation for the conversion of nitrogen monoxide to nitrogen dioxide)
5. 4NO2 + 2H2O + O2 -> 4HNO3 (Balanced equation for the formation of nitric acid)
6. 4As + 3O2 -> 2As2O3 (Balanced equation for the combustion of arsenic)
7. CH4 + 2O2 -> CO2 + 2H2O (Balanced equation for the combustion of methane)

These are the balanced chemical equations for the reactions you've mentioned. If you have any specific questions or need further explanations, please let me know.
