Can you mix oxygen with water to make acid?
No. You would just get water with some dissolved oxygen in it. This dissolved oxygen is essential for most aquatic life. Acids are a variety of substances that will increase the concentration of hydrogen ions when added to water.
If you held your breath what would happen to the concentration of oxygen in your lungs?
If you held your breath, the concentration of oxygen in your lungs would decrease. The concentration of carbon dioxide would increase in your lungs.
Why does water generally move in the opposite direction of dissolved substances?
Diffusion is the process of a substance moving from an area of a higher concentration to a lower concentration. In this scenario the dissolved substance is the higher concentration and the water would go to an area with the lower concentration.
Where would carbon dioxide concentration be the highest?
The carbon dioxide concentration would be the highest where the oxygen is low.
What happens if there is too much oxygen in seawater?
Oxygen in the water is called "dissolved oxygen" because quite simply it is just that. The air naturally diffuses into the water and can reach equilibrium with the water. It is virtually impossible to get too much dissolved oxygen in the water because the excess will convert back to gas and bubble out of the water like so much soda water when you pour it out of the bottle. This said, there is no concern for too much dissolved oxygen in the water. Concern arises when dissolved oxygen levels get too low. When this happens more sensitive plants and animals become weak or die. As a side note, weather, temperature, and salinity all effect dissolved oxygen levels. Faster moving water contains more dissolved oxygen because it has more contact with the air than still water. Cold, fresh water holds more oxygen than warm or salty water. This would mean a cold, fast moving, fresh water stream or river would contain the highest amounts of dissolved oxygen, and the salinity of the ocean water would not be ideal for holding as much dissolved oxygen.

What is the typical limiting factor in streams lake and freshwater environment?
Factors that limit aquatic life are - Temperature - Access to sunlight - Dissolved oxygen concentrations - Availability of nutrients, such as nitrogen and phosphorus
What would happen to the amount of dissolved oxygen in the river if the river is polluted?
the amount of dissolved oxygen would decrease.
Which region would you expect to find the largest amounts of dissolved oxygen in the ocean water?
In polar oceans because the solubility of oxygen increases with decreasing temperature
If you held your breath what would happen to the concentration of oxygen in your lungs?
If you held your breath, the concentration of oxygen in your lungs would decrease. The concentration of carbon dioxide would increase in your lungs.
Where would you expect to find the largest amounts of dissolved oxygen in the ocean water?
Oxygen best dissolves at surfaces. So generally, you would find the largest amount of dissolved water at the surface, which is in contact with the air. As for a region, I would assume a region that has a lot of photosynthetic organisms and not a lot of oxygen consumers. Another factor that should be kept in mind, is that the lower the concentration of solutes (i.e.. salt) in the water, the more oxygen can be dissolved. For example, at 10 degrees Celsius, up to 8.02mL of oxygen can be present per liter of freshwater, but only 6.75mL of oxygen is dissolved per liter of saltwater. ______________ In polar regions.

How would the concentration of ozone molecules change if the concentration of oxygen molecules decreased?
If oxygen decreased, ozone will decrease. It is because ozone is made from oxygen.
Which would increase the amount of dissolved oxygen in a pond?
air
Where would carbon dioxide concentration be the highest?
The carbon dioxide concentration would be the highest where the oxygen is low.

Would you expect a fast moving mountain stream or the Mississippi River to have more dissolved oxygen?
I personally would expect the mountain stream to have more dissolved oxygen, because I know that oxygen dissolves better in cold water.
