## Question:

Balance the following chemical equations with the smallest integer coefficients.

**_NH_3(g) +**_O_2(g) ?**_NO(g) +**_H_2O(g);

**_Al(s) +**_HCl(aq) ?**_AlCl_3(aq) +**_H_2(g);

## Balancing a Chemical Equation:

A chemical equation represents the species involved in the chemical reaction.

It is balanced in order to make the number of atoms and the charge equal on both sides of the equation due to the conservation of mass and charge.

One of the common methods of balancing a chemical equation is the *hit and trial* method in which the correct coefficients are guessed.
