The balanced equation is P4O10(s) + 6H2O(l) yields 4H3PO4(l). This reaction is carried out using 10.0 g of P4H10 and 60.0g of H20. A) Determine the limiting reagent. B) List all compounds that are present when reaction is complete. C) Determine the theoretical yield of H3PO4 based on the starting materials and D) Determine the mass, in grams, of each compound present when the reaction is complete
