You just used the last of your breakfast cereal to make yourself a fresh bowl. after eating a couple of spoonfuls, you notice that the printing on the box claims that your cereal has the most metallic iron of any breakfast cereal on the planet. now, your only sample of the breakfast cereal contains bran flakes, raisins, milk, and sugar. you decide to find out if the claim regarding the iron is true. how would you separate the mixture to collect the iron?

You can separate the mixture to collect the iron using a magnetic.

Explanation:

The printing on the box claims that your cereal has the most metallic iron of any breakfast cereal on the planet.

The last sample of the breakfast cereal contains bran flakes, raisins, milk and sugar. We need to analyze the iron content.

There are several chemical and physical experiments about this topic, the simplest is: You can use a magnetic material, the magnetic field of the material will affect the mixture previously prepared. In that way, only the metallic iron will move with the magnetic field movements. So, you can separate the metallic iron from all the other compounds. 

catya your not at all which answer i've seen you do this on another question!

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
