Question 1

What is the concentration of the Cd2+ion in a 0.035 M Cd(NO3)2solution that is also 1.0 M NH3? At this temperature, Kffor Cd(NH3)42+= 1.0 107.

3.5 10–9M
6.4 10–9M
3.5 10–30M
1.0 10–7M
None of these are correct.

Question 2

What is the maximum concentration of carbonate ions that will precipitate BaCO3 but not MgCO3 from a solution that is 3.5 10–3M each in Mg2+ and Ba2+? For MgCO3, Ksp = 1.0 × 10–15 and for BaCO3, Ksp = 2.6 × 10–9.

2.9 × 10–13M
7.4 × 10–7M
3.2 × 10–8M
5.1 × 10–5M
None of these are correct; MgCO3will always precipitate before BaCO3.

A recent study has found that following a diet rich in berries may slow down the aging process of the brain. This diet apparently helps to keep dopamine levels much higher than are seen in normal individuals who do not eat berries as a regular part of their diet as they enter their later years.

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.

On average, someone in the United States has a stroke about every 40 seconds. This is about 795,000 people per year.

Liver spots have nothing whatsoever to do with the liver. They are a type of freckles commonly seen in older adults who have been out in the sun without sufficient sunscreen.
