What is the freezing point of ocean water?
The fixed ratio of ions in seawater is always constant.
What is the Rule of Constant Proportions?
Any question that has to do with the rule of constant proportions.
Shells become deformed and begin to dissolve, interferes with other organisms' senses.
What are some effects of Ocean Acidification
Anything to do with Ocean Acidification
H+
How is a hydrogen ion written
what is a hydrogen ion
Why does deep, cold water hold more dissolved gases?
High pressures and low temperatures increase the solubility of dissolved gases.
When the gases are dissolved, it brings the density of the seawater up and so it sinks to the bottom.
8.2 ---> 8.1
What affect did ocean acidification have on the ocean's pH?
What is the ocean's pH?
Holds more gas
What does seawater with low salinity do?
What is special about low salinity sea water?
Red, Orange, Yellow, Green, Blue, Indigo, Violet, Blue
What is the order of visible light that gets absorbed first in water?
CaCO3
what is the material that most mollusks, crabs, and corals contain in their shells.
Name all 6 major ions found in seawater
Chloride, Sodium, Sulfate, Magnesium, Calcium, and Potassium
N2, O2, CO2
What is the order of dissolved gases in the ocean from most abundant to least abundant?
P1V1 = P2V2
What is Boyle's Law?
Capillary action, polarity, less dense when solid.
What are some important characteristics of water
H2CO3
What is carbonic acid?
What is the carbonic acid formula?
The bends
Decompression sickness. (DCS)
Dive too deep and come up too fast, and the nitrogen in your blood stream will form gas bubbles. (Not to be confused with nitrogen narcosis which is when there's too much nitrogen in the blood while scuba diving)
4C
Chemical properties of the elements vary periodically according to their atomic numbers.
What is the periodic law?
The reason salt water conducts electricity
ionic compounds conduct electricity when dissolved due to free moving metallic elements.
CO32-
What is the chemical formula of a carbonate ion
what is a carbonate ion
Proust's Law
Another name for the rule of constant proportions
50-80%
How much of earth's oxygen comes from the ocean?
The body's cells require a balance of salts in order to carry out chemical processes. Too much of it can be deadly.
Our kidneys cannot rid the body of enough salt in order for this action to be safe.
Why shouldn't you drink seawater?
Abundance of OH- ions
What does it mean when something is basic/alkaline
anything to do with a pH < 7
What is going on at an atomic level when gases are being dissolved in seawater? (Think IMFs)
Solute-solute interactions are being disrupted and so are solvent-solvent ones. As a result, solvent-solute interactions form.
interactions between solvent and solutes particles will compete with solvent particles.
Solvent-solute interactions are strong enough to overcome solvent-solvent and solute-solute interactions.
