Question

The element phosphorus is manufactured from a mixture of phosphate rock (Ca3(PO4)2), sand (SiO2), and coke (C) in an electric furnace. The chemistry is complex but is summarized by these two equations.

A. Ca3(PO4)2 + SiO2 --> P4O10 + CaSiO355

B. P4O10 + C -->P4 + CO
How many grams of phosphorus are produced?
How many grams of carbon are consumed?
need work as well pleasee!

Answer 1

2Ca3(PO4)2 + 6SiO2 + 10C ---> P4 + 6CaSiO3 + 10CO

1 mole of Ca3(PO4)2 = 310g

1 mole of P4 = 124g

according to the reaction:

2*310g Ca3(PO4)2----------------124g P4

x g Ca3(PO4)2 ------------------------ 30g P4

x = 150g Ca3(PO4)2
