Answer to Question #189812 in General Chemistry for khaled

Question

1.   Calcium phosphate, silicon dioxide, and coke may be heated together in an electric furnace to produce phosphorus, as shown in the following equation:

2 Ca3(PO4)2(s) + 6 SiO2(s) + 10 C(s) → 6 CaSiO3(s) + 10 CO(g) + P4(g)

In this reaction, what mass of calcium phosphate would be needed to make 100.0 g of phosphorus? What mass of calcium silicate would be formed as a by-product

Answer 1

Mass of calcium phosphate needed ;

=47.9g

Mass of calcium silicate needed =90. 4g
