The first compound contains 53.64% cobalt, 43.64% oxygen and 2.73% hydrogen. The second compound contains 48.85% oxygen, 27.48% magnesium, and 23.66% phosphorus. (a) What are the empirical formulas for each compound, (b) what are the names of each compound, (c) if these 2 compound were to react together, what would the overall equation look like reactants and products, (d) write out the balanced formula for that entire equation hint, the first compound has 2 moles and the second compound has 1 mole, and (e) what would be the percent composition of the combined oxygen, only on the reactant side using only the empirical formula?

a polar bond is formed when electrons are shared unevenly between atoms

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
