Question
Calcium phosphate, silicon dioxide, and coke may be heated together in an electric furnace to produce phosphorous 2 Ca3(PO4)2 + 6 SiO2 +10C--> 6CaSiO3 +10 CO+ P4 In this reaction how much calcium silicate would be formed as a by-product? How much sand would be used up in the same reaction?

How much sand would be used up in the same reaction?Explanation / Answer
Note - There are no values, hence i have given the answer in terms of moles
Since the product we are interested is P4, hence one mole of P4 is produced when 2 mole of Calcium phosphate and 6 moles of SIO2 reacts
Hence 6 mole of CaSiO3 would be produced for each mole of P4
Sand (SiO2) for making one mole of P4, we will be required 6 moles of Sand (SiO2) for teh formation of one mole of P4
