Balancing Reactions with Cl2O7

The video tutorial explains how to balance the chemical equation for the decomposition of Cl2O7 into Cl2 and O2. It begins by identifying the number of chlorine and oxygen atoms on each side of the equation. The tutorial then demonstrates how to balance the oxygen atoms by adjusting coefficients, followed by balancing the chlorine atoms. The final balanced equation is presented, along with a brief mention of the states of matter for each compound. The video concludes with a summary of the process.
