Oxygen that is dissolved in the water crossed ghe gill menbrane by diffusion. The oxygen is dissolved in the water like carbon dioxide in a beer. This oxygen is not a part of the water molecule. The oxygen in the water molecule is not available to the fish, when dosolved oxygen gets low, yhou have a fish kill.

How do you separate Hydrogen and Oxygen gases in industrial electrolysis of water process?
In electrolysis, oxygen and hydrogen gas are produced at different electrodes (oxygen at the anode and hydrogen at the cathode). Since these electrodes do not have to be in close proximity, the hydrogen and oxygen will bubble upwards into separate collection vessels. If you needed to separate hydrogen and oxygen once mixed, the easiest way I can think of would be to cool the mixture to ~60K. At this point the oxygen would condense and leave hydrogen gas.
Why do fish use 15 percent of their energy to move water over its gills?
To breath by extracting oxygen from the water.
How much oxygen is in the sea?
Much less than the approximate 21% in the air. Perhaps half that. Fish need a large energy expenditure to strain oxygen from the water. Most of the oxygen produced by phytoplankton, for instance, is vented into the atmosphere.
Can you list out topics for paper presentation on renewable energy?
solar energy is one of the best renewable energy resources and new mechanism to efficiently convert the solar energy to mechanical energy are being developed. Lot of R&D is going on in to this topic in the labs of MIT. It deals with breaking water into hydrogen and oxygen. you can follow it up from this link. http://web.mit.edu/newsoffice/2008/oxygen-0731.html
How many liters of water are needed to react with 2L of oxygen to make water?
Water does not need to react with oxygen to make water!
Fish can extract oxygen from water using what?
Fish have lamellae in their gills. As the water flows through the gills and over the lamellae, the oxygen is extracted from the water.
Would it be easier to separate the sugar from the water or to split water into hydrogen and oxygen?
It is easier to separate sugar from water through physical processes like evaporation or filtration. Splitting water into hydrogen and oxygen requires a chemical process called electrolysis, which typically involves passing an electric current through water, making it more complex and energy-intensive compared to separating sugar from water.
How does the thickness of lamellae affect the oxygen uptake by a fish's gills?
Thicker lamellae allow for a larger surface area for oxygen exchange to occur, leading to increased oxygen uptake by a fish's gills. This is important for efficient respiration and meeting the oxygen demands of the fish's body. Thinner lamellae would result in a smaller surface area and potentially limit the fish's capacity to extract oxygen from the water.
How do fish get oxygen from under water?
Fish gills contain rows upon rows of lamellae, which are thin, disc-like membranes loaded with a capillary network. The water flows across the lamellae, and oxygen and carbon dioxide are exchanged directly across the capillary membrane. Humans have similar capillary interchange sites in the lungs, and the gas exchange occurs in much the same fashion, only the fluid from which we get our oxygen is air, whereas fish get their (dissolved) oxygen from the water.
What is produced when a compound is heated?
Your question is invalid, your question should be What is separated when a compound is heated, because heating a substance is basically adding energy to it. and the energy is likely to separate compounds. For example when you add electricity(energy) to water it will separate water into oxygen and hydrogen. It will also apply for heat energy, If you add enough heat to separate the bond of water.
What kind of energy is used when water decomposes?
To separate water into hydrogen and oxygen, electrolysis is usually used; this uses electrical energy. Of course, the electrical energy can be generated in any of several ways.
What do the alveoli of the lungs the microvilli and villi in the intestine and the gill lamellae in fishes gills have in common?
The microvilli and villi in the intestine increase the absorbent surface where nutrients are transported into the blood. The alveoli in the lungs and gill lamellae bring oxygen in the air and water to the bloodstream,
What is used to separate hydrogen and oxygen?
Electrolysis is commonly used to separate hydrogen and oxygen. In this process, an electric current is passed through water, causing it to split into hydrogen and oxygen gases.
Which of these best describes the formation of the lowest energy state of water?
The lowest energy state of water is achieved when the hydrogen atoms are covalently bonded to the oxygen atom through shared electrons. This bond formation releases energy, resulting in a stable water molecule with a bent shape and a lower potential energy compared to the separate hydrogen and oxygen atoms.
Fish breathe oxygen which is dissolved in water what kind of solution?
Fish breathe through their gills, extracting dissolved oxygen from water. This process is possible due to the fish having specialized structures in their gills called lamellae, which increase the surface area for gas exchange. The oxygen in water is in the form of a solution, specifically a solution of oxygen gas in water.
How does the electron chain transfer light energy in photosynthesis?
Light breaks down water into hydrogen and oxygen, the oxygen is then released. Next the hydrogen and its electron separate so that they are H+ and e-. The electrons are dragged across which creates massive energy.
What do fishes use their gills to do?
Fish's gills are made up of a gill bar, gill filaments, gill rakers and gill lamellae. The gill filaments are "stacked" along the the gill bar and the gill lamellae stick out of the filaments at right angles. Deoxygenated blood is carried down the gill bar and into the gill filaments. It then flows through the lamellae and back down the other side of the filament, into the gill bar where the now oxygenated blood gets carried off for use. The way oxygen is diffused into the lamellae is through a countercurrent exchange system. The fish takes in water through the mouth, and pushes it over the the gill filaments and lamellae. The direction of blood flow through the filaments and lamellae is in the opposite direction to the water being forced over them. This means that there is always a good diffusion gradient and the maximum amount of oxygen can be absorbed. If the concurrent exchange system was used, whereby the water and blood would flow in the same direction, only about half of the oxygen in the water would be able to be absorbed. The water is now forced back out of the fish through the operculum.
