Question

Balance:-

• Chlorine reacts with oxygen to form chlorine heptoxide
• Carbon reacts with oxygen to give Carbon monoxide
• Nitrogen reacts with oxygen to give Nitrogen monoxide
• Hydrogen burns in presence of air to form water
• Magnesium burns in presence of nitrogen to form Magnesium Nitride

Answer 1

The balanced equations are:
$$\begin{gathered} 1)2C{l}_2+7O_2\to 2C{l}_2{O}_7 \\ 2)2C+O_2\to 2CO \\ 3)N_2+O_2\to 2NO \\ 4)2H_2+O_2\to 2H_{2}O \\ 5)3Mg+N_2\to M{g}_3{N}_2 \end{gathered}$$
