Question

balance the following equation
1) H2+O2__H20
2) N2+O2__N0
3)Mg+02__MgO​

Answer 1

Answer:

1. 2H+O2----->H2O

2.N2+O2----->2NO

3.2Mg+O2----->2MgO

Answer 2

$\boxed{ \begin{array} {c} \huge\tt{H_2 + O_2 \longrightarrow H_2O} \\ \\ \\ \sf\red{2H_2 + O_2 \longrightarrow 2H_2O} \end{array}}$

$\boxed{\begin{array}{} \huge</p><p> \tt{N_2 + O_2 \longrightarrow NO} \\ \\ \\ \red{\sf N_2 + O_2 \longrightarrow 2NO}</p><p>\end{array}}$

$\boxed{\begin{array} {c} \huge</p><p>\tt Mg + O_2 \longrightarrow MgO \\ \\ \\ \sf\red{2Mg + O_2 \longrightarrow 2MgO}</p><p>\end{array}}$
