A chemist fills a reaction vessel with 0.220 g aluminum hydroxide (Al(OH)_3) solid, 0.209 M aluminum (AI^3+) aqueous solution at a temperature of 25.0 degreeC. Under these conditions, calculate the reaction free energy DeltaG for the following chemical reaction: Al(OH)_3(s) Al^3+(aq) + 3OH^- (aq) Use the thermodynamic information in the AiLEKS Data tab.

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

yes the answer is total mass in unchanged   : )

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
