Predict whether the following double-replacement reaction will produce a precipitate: mgcl2 + li2co3 mgco3 + 2 licl.
no; all products are soluble
yes; the mgco3 will precipitate
yes; the licl will precipitate
yes; both the mgco3 and the licl will precipitate

Option (b) is the correct answer.

Explanation:

A solid that is insoluble in an aqueous solution is known as a precipitate. Also, a chemical reaction in which a precipitate is formed is known as a precipitation reaction.

For example,

Hence, here is the precipitate as it is the insoluble solid which is formed when two aqueous solution magnesium chloride and lithium carbonate chemically combine together.

Thus, we can conclude that yes the given double-replacement reaction will produce a precipitate, the will precipitate.

am i too late?

explanation:

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
