    I liked how you gave all your references but mostly the salt concentration affecting dissolved oxygen was interesting. Though i still don't fully understand Eutrophication.

      There are certain elements that serve as food for living things such as trees and underwater plants. These are nutrients that help them grow, such as... phosphorous, nitrogen, etc. Just like humans can get sick from consuming too much, so can plants. This makes them grow at a rate higher than normal, not allowing the ecosystem in the water to work the same. Fish may not be able to swim in open water because the plants in the water are so overgrown. These excess elements in the form of food for the plants, usually come from waste from factories and stuff like that. So that is why the speaker talked about trash. Eutrophication is when a body of water becomes extremely filled with those plants, phytoplankton, etc. and there is not enough space for "normal conditions" for fish, humans, and other living organisms! I Hope this helped :)

    Great info. The o2 air saturation was not something I'd considered regarding liberating oxygen from water, and didn't know if water could hold addition Oxygen

    I thought animals "breathe" in the oxygen from the water molecule, itself. Water is H2O. I thought they just took the O, and the hydrogen would evaporate until it joined with more oxygen to become water again. I don't have a clear understanding of how dissolved oxygen doesn't connect to the H2O molecules and become h2o2. Or, for that matter, why other molecules (like nitrogen) don't connect with the H2O molecules when they enter and dissolve in water.

    • @herminenamakalu4171
      @herminenamakalu4171 Месяц назад

      Not quite. The biggest misunderstanding is the strength of the forces that hold the chemical bonds together. Thereby resulting in a stable molecule like water. H20 is a molecule held together by covalent bonds and the way Oxygen and Hydrogen are bonded together isn't a casual bond . It's incredibly strong. There is a strong pull of those 2 to each other that's why they are a bond. You can't just pick molecules apart casually without applying force that is stronger than what brought them together in the first place. For example if you have NaCl ( Table salt) You cant just get the Chlorine or Sodium from there casually. If that was the case our universe wouldn't really have molecules.
      I'll give some numbers: bond dissociation energy of water is about 463 kJ/mol. which means you need that much energy in KILOJOULES!!! to break apart just 18g of water. :(. Imagine a bond of water :(
      That's why to decompose Water into Hydrogen (H2) and Oxygen (O2) for example , it takes a process called Electrolysis ( Which means applying electrical current to the water solutions with an electrolyte and electrodes to break it apart) . This same process is what you would use to to decompose NaCl and other molecules . Note that electricity is used. Which is something that uses a lot of energy. Not boiling or melting. If you boil water, The water vapour is still H2O steam, the chemical composition doesn't change one bit. Only the state : i.e. It's no longer liquid water but gaseous water.
      PS. Nitrogen molecule is not very reactive... It occurs as N2. And appears satisfied..

    water = Hydrogen+Oxygen
    so when fish "breathe" are they breaking the chemical bonds in water to extract oxygen ( and liberate hydrogen) or are they only ever pulling out free oxygen that is mixed into water ( not part of it)

    How does a non-polar molecule dissolve in a polar dissolvent? Is there some kind of phenomenon with H bridges or another solute?

    • @herminenamakalu4171
      @herminenamakalu4171 Месяц назад

      Fantastic question. You are eluding to hydrogen bonding . And it is exactly how it sounds, which is a Hydrogen atom from one molecule forming a weak but significant bond to another Electronegative atom( Nitrogen /Fluorine/Oxygen) . Often times, the molecules can then arrange themselves into web-like structures. A picture will this explain clearer. Any person interested in water of Fluids or any material science at all should definitely read and understand INTERMOLECULAR FORCES as they explain so much . Things like surface tension, solubility , density(especially that of water ) , viscosity and many others are explained by hydrogen bonds

    Really well done. I'd like to know though how much of the 'trash' is chemical (fertilizers) or animal waste runoff from agriculture vs. population centers (storm runoff, untreated sewage). The garbage truck image is misleading. I'd guess very little of the 'trash' is what we typically think of as trash: plastic, paper, etc.

    • @lepidlover0557
      @lepidlover0557 5 лет назад

      Because it's too hot.
      The hotter a liquid is, the less dense it is, therefore the less oxygen it holds.

    If the oxygen the plants produce is consumed when the plan dies, the fact that the plants are many or few doesn't change the oxygen content of the water and it is incorrect to say that plants are one of the ways in which oxygen is introduced into the water, because those plants will die in the water in any case.
