Lars is balancing equations with his study group. He is unsure about one equation because each member of the study group came up with a different answer. Which is the proper way to balance the equation Ca(OH)2 + H3PO4 → Ca3(PO4)2 + H2O? Ca(OH)2 + H3PO4 → Ca3(PO4)2 + 6H2O 3Ca(OH)2 + 2H3PO4 → Ca3(PO4)2 + 6H2O 3Ca(OH)2 + 2H3PO4 → Ca3(PO4)2 + 3H2O Ca(OH)2 + 2H3PO4 → Ca3(PO4)2 + 6H2O
