How are you supposed to balance out P4 -> PH3?

You will first start off by balancing the P, and then balance the hydrogens by adding one water molecule for each hydrogen that is needed. Balance the O by adding the same number of OH- ions to the opposite side and then add the appropriate number of electrons balance the charges.

Yes! Always use the order balance main elements, balance H/O, then balance charge.

Also, depending on whether the reaction is happening in base or acid, you may need to add either protons or hydroxide ions.
