Oxygen does dissolve into sea water, as do many other gasses such as CO2.
No. Freshwater does not have the same amount of dissolved materials as sea water. Sea water has a much greater amount of salt dissolved in it.
They breathe by the constant flow of water through their bodies by way of bodily pours and they take up the dissolved oxygen, just like fish do with their gills.
yes
Water is a compound because all of its molecules are identical (except for occasional isotope variations) and contain at least two elements and it has constant proportions between its hydrogen and oxygen contents. Sea water is a mixture because it contains dissolved constituents, composed of at least some atoms other than hydrogen and oxygen, with no chemical bonds between these dissolved constituents and the water molecules, and it has varying proportions.
If the sea surface temperature in the Antarctic Ocean increases due to global warming, the dissolved oxygen levels in its deep water are likely to decrease. Warmer water holds less oxygen, which can lead to hypoxic conditions and negatively affect marine life. Additionally, changes in ocean circulation patterns may further disrupt oxygen distribution in deeper waters. This can have cascading effects on the entire marine ecosystem.
Oxygen is more soluble in fresh water than it is in sea water, therefore there is more dissolved oxygen in river water than sea water.
Definitely not. The fish in the sea take in the dissolved oxygen in the sea thru their gills.
Same way other fish get oxygen. Push water over their gills and removed dissolved oxygen from the water
Sea water is a liquid. It consists of dissolved salts and other minerals in water.
No. The extract dissolved oxygen from water.
I think its mercury
Most get it from the dissolved oxygen in the water through their gills. Others, such as sea mammals, dolphins etc, need to surface to breathe
It depends! On what you say? Well, as an example it depends on the temperature of the sea water. The colder the water the greater the amount of DO can be contained. It depends on where the sea water is located; e.g., sea water at the mouth of the Amazon River (or at the mouth of most any river emptying into the oceans) for the fresh water from the river dilutes the salt content of the sea water there.
The most common substance dissolved in sea water is salt, specifically sodium chloride. Other substances found in sea water include magnesium, calcium, and potassium ions, as well as various gases such as oxygen and carbon dioxide.
No. Freshwater does not have the same amount of dissolved materials as sea water. Sea water has a much greater amount of salt dissolved in it.
When an ionic salt like NaCl is added to water, the ions from the salt introduced will attract the water molecules in an effort to "solvate" the ions. This has the tendency to decrease the weak affinity of non-polar oxygen molecules to water and drive the dissolved oxygen out of the polar water. In general, the solubility of a gas in a solvent is affected significantly by the presence of other solutes in the solution.
Sea water is mostly water and sodium chloride. However, other compounds that are present include potassium chloride, calcium carbonate, dissolved carbon dioxide, oxygen, etc..
