The major industrial method for the preparation of elemental phosphorus is heating a mixture of phosphate rock, carbon, and sand in an electric furnace. The chemical reactions can be represented by:

Ca3(PO4)2 + SiO2 --> CaSiO3 + P4O10

AND

P4O10 + C --> P4 + CO

A) Balance the equations

B) Calculate the percentage of Ca3(PO4)2 initially present in the rock sample if 307 kg of phosphate rock yields 42.5 kg of elemental P4.
