Question

Complete and balance the equation

$\mathrm{CO}+{\mathrm{H}}_2\to$

Answer 1

When carbon monoxide reacts with hydrogen it gives methyl alcohol 0r methanol.

• The complete reaction is :

${\mathrm{H}}_2\left(\mathrm{g}\right)+\mathrm{CO}\left(\mathrm{g}\right)\to {\mathrm{CH}}_3\mathrm{OH}\left(\mathrm{l}\right)$

• The Chemical equation is not balanced. the number of atoms of carbon and oxygen is equal on both sides, but not hydrogen
• So let's balance the number of atoms on both sides equally. as the number of hydrogen on the product side is 4 and on the reactant side is 2, so make it equal by making 4 atoms on the reactant side also.

$\underset{\mathbf{Hydrogen}}{\mathbf{2}{\mathbf{H}}_{\mathbf{2}}\mathbf{\left(}\mathbf{g}\mathbf{\right)}}\mathbf{}\mathbf{+}\underset{\mathbf{Carbon}\mathbf{}\mathbf{monoxide}}{\mathbf{}\mathbf{CO}\mathbf{\left(}\mathbf{g}\mathbf{\right)}}\mathbf{}\mathbf{\to }\underset{\mathbf{Methanol}}{{\mathbf{CH}}_{\mathbf{3}}\mathbf{OH}\mathbf{\left(}\mathbf{l}\mathbf{\right)}}$

Now, the chemical equation is balanced.
