Question

balance the equations
nitrogen + oxygen= nitric oxide
nitrogen and hydrogen = amonia
iron + sulphur = iron sulphide
magnesium + oxygen = magnisum oxide

Answer 1

Explanation:

1)N2+O2→NO

balanced=

N2+O2→2NO

2)N2+H2→NH3

balanced=

N2+3H2→2NH3

3)Fe + S → FeS

already balanced

4)Mg+O2→MgO

balanced=

2Mg+O2→2MgO
