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.

The image compares the arrangement of electrons in two different neutral atoms. a figure labeled atom q has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has six black spheres. to the left of this figure is another figure labeled atom p. atom p has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has seven black spheres. which of the following best explains the position of the two atoms in the periodic table? atom p has an estimated zeff of 7 and is therefore to the left of atom q, which has a zeff of 6. atom p has an estimated zeff of 7 and is therefore to the right of atom q, which has a zeff of 6. atom p has an estimated zeff of 5 and is therefore below atom q, which has a zeff of 4. atom p has an estimated zeff of 5 and is therefore above atom q, which has a zeff of 4.
