how do you make

PCI3+CI2 =PCI5 a balanced equation

To balance the equation PCI3 + CI2 = PCI5, you need to ensure there are an equal number of atoms of each element on both sides of the equation.

Looking at the equation, you have one phosphorus (P) atom on the left side and one phosphorus (P) atom on the right side, which is already balanced.

Next, you have three chlorine (Cl) atoms on the left side and two chlorine (Cl) atoms on the right side. To balance this, you can add a coefficient of 2 in front of CI2 on the left side, so you would then have 2 CI2 on the left side and 4 chlorine (Cl) atoms.

The balanced equation would then be:
PCI3 + 2CI2 = PCI5
