Hello

For a lab, it is stated that potassium chlorate, water, iodine and HCl are used in a reaction to produce ICl3. I need to determine a balanced equation to represent this synthetic reaction but I don't know how to do that with more than two reactants. I know that ICl3 is one of the products but I have no idea what happens to the rest. Can anyone help me to solve this and explain how they got the answer? If possible, could you also give tips or explain how to approach synthesis reactions such as these and how to determine what products come from them?
