Question

i. determine the mass of reactants and products that will be needed if one mole of p4(s) reacts completely, as follows p4(s) 6 h2(g) →4 ph3(g) ii. what is the total mass of the reactants? what is the mass of the products? iii. what principle is illustrated by this example?

Answer 1

one mole of P4 react with 6 mole of hydrogen to form 4 moles of phosphine. The mass of reactant is 132g ( 30 x 4 + 6 x 2). The mass of product is 132g (4 x33). This justify law of conservation of mass.

The class of chemicals known as organophosphorus compounds includes phosphonate. Philippe Gengembre initially discovered this chemical in the year 1783. By heating up phosphorus in an aqueous solution of potassium carbonate, he was able to produce phosphine. This substance has the chemical formula PH3. This substance is present in the atmosphere in varying concentrations. It is essential to the biochemical cycle of phosphorus.

​Hence, phosphine is produced from phosphorous and hydrogen.
