Question

Complete and balance following equations $\mathrm{CO}+{\mathrm{H}}_2\to$

Answer 1

The representation of a chemical reaction in the form of symbols (substances) is known as a chemical equation. A chemical equation consists of reactants, products and an arrow showing the direction of the reaction. The equation in which the number of atoms of all the molecules is equal on both sides of the equation is known as the balanced chemical equation.

In order to balance this equation we will follow these steps

$\mathrm{CO}+{\mathrm{H}}_2\to {\mathrm{CH}}_3\mathrm{OH}$

Atoms	LHS	RHS
C	1	1
O	1	1
H	2	4

There are 2 H on the left and only 4 on the right. A coefficient of 2 for H₂ will satisfy the mass requirements

$\mathrm{CO}+2{\mathrm{H}}_2\to {\mathrm{CH}}_3\mathrm{OH}$

Atoms	LHS	RHS
C	1	1
O	1	1
H	2X2=4	4

$\mathrm{CO}\left(\mathrm{g}\right)+2{\mathrm{H}}_2\left(\mathrm{g}\right)\to {\mathrm{CH}}_3\mathrm{OH}\left(\mathrm{l}\right)$ is the balanced chemical equation.
