1. The problem statement, all variables and given/known data Ca3(PO4)2 + C + SiO2 --> CaSiO3 + CO + P4 2. Relevant equations 3. The attempt at a solution I'm okay with balancing reactions that have 2 reactants but when there's 3 i take an extremely long time to do it. is there any easy way or strategy to go about balancing these kinds of equations?
