Is sea water the same as water?
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.
How do sea anemones breath?
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.
Is seawater is mixture?
yes
Why is water classified as a compound and sea water a mixture?
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.
The most abundant gas dissolved in sea water is a nitrogen b carbon dioxide c oxygen d argon e hydrogen?
Nitorgen is the most abumdant dissolved gas in Seawater, at about 48%. The upper layers of ocean water are usually saturated with nitorgen gas. -information from "Oceanography, An invitation to Marine Science, 6th Ed."
More oxygen sea water than river water?
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.
Does dissloves oxygen in water harmful?
Definitely not. The fish in the sea take in the dissolved oxygen in the sea thru their gills.
How does a leafy sea dragon get oxygen?
Same way other fish get oxygen. Push water over their gills and removed dissolved oxygen from the water
Is sea water a solid liquid or gas?
Sea water is a liquid. It consists of dissolved salts and other minerals in water.
Can jellyfish breathe on land?
No. The extract dissolved oxygen from water.
What gas that obtained sea water?
I think its mercury
Where do animals that live in water get oxygen from?
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
How much dissolved oxygen in a gallon of sea water?
The amount of dissolved oxygen in seawater can vary widely depending on factors like temperature, salinity, and level of organic matter. On average, seawater may contain around 5-10 milligrams of dissolved oxygen per liter, which would translate to approximately 19-38 milligrams of dissolved oxygen in a gallon (3.8 liters) of seawater.
What is the most common substance dissolved in sea water?
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.
Is sea water the same as water?
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.
Why does salinity cause a decrease in dissolved oxygen?
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.
What compound are in sea water?
Sea water is mostly water and sodium chloride. However, other compounds that are present include potassium chloride, calcium carbonate, dissolved carbon dioxide, oxygen, etc..
