Jack prepared two glasses half full of room temperature water. He added a whole Alka-Seltzer® antacid tablet to glass #1 and a crushed Alka-Seltzer® antacid tablet to glass #2. He stirred the mixtures in both glasses at the same time. After one minute, he observed that there was still some antacid at the bottom of glass #1 while all the antacid in glass #2 disappeared. Why does increasing the surface area of antacid affect its rate of dissolving in water?

It decreases the size of the water particles and the amount of water that are in contact with the antacid particles.
It decreases the surface area of water that is in contact with the antacid, making the antacid less soluble in water.
A. It increases the area of the antacid that is in contact with water, allowing water to B. get to the particles more easily.
C. It increases the size of the antacid particles and makes them spread more easily among the water particles.

no but i do not usually comment or use my voice that much when it comes to social media

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
