The video tutorial demonstrates how to balance the chemical equation for the decomposition of ammonium nitrite (NH4NO2) into water (H2O) and nitrogen gas (N2). It begins by counting the atoms on each side of the equation, identifying the need to balance the number of nitrogen, hydrogen, and oxygen atoms. The instructor then explains how to adjust the coefficients to achieve a balanced equation, ensuring that the number of each type of atom is equal on both sides. The video concludes with a confirmation that the equation is balanced and a thank you to the viewers.
