how to make PCI5 = PCI3+CI2 a balanced equation

To make the equation balanced, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

The unbalanced equation is:
PCI5 = PCI3 + CI2

There are:
- 1 phosphorus (P) atom present in PCI5
- 1 phosphorus (P) atom present in PCI3
- 1 carbon (C) atom present in PCI5
- 1 carbon (C) atom present in PCI3
- 5 iodine (I) atoms present in PCI5
- 2 iodine (I) atoms present in CI2

To balance the equation, we can multiply PCI3 by 2 and CI2 by 5 to match the number of atoms on both sides of the equation:

2PCI5 = 2PCI3 + 5CI2
