When the water warms up, the concentration of dissolved oxygen in the water decreases and this reduces the chance that the salmon eggs will survive. And the trees also help keep the soil on the banks of the stream in place. Salmon cannot spawn in streambeds clogged with sediment, dirt, ...
When logging removes the trees, the streams are open to the sun and the water becomes warmer. When the water warms up, the concentration of dissolved oxygen in the water decreases and this reduces the chance that the salmon eggs will survive. And the trees also help keep the soil on the...
What is the reason for ice being less dense than water? How does climate change affect water levels? Why does the level of water seem to not rise when salt is dissolved in water? Why does cold water hold more salt? How can surface runoff affect the water quality? Why is it hard to ...
Water also contains dissolved oxygen (O2) molecules. All electronics contain PCBs (printed circuit boards). PCBs have metals like Copper, Gold and Palladium as conductors. When exposed to water, aredox reactionoccurs where the metal loses electrons and forms a metal-oxide layer. Overtime, this ...
4: Chilled water sanitary asepsis An important cause of intestinal diarrhea in many patients is excessive drinking of cold water. Drinking raw water to loose bowels is common sense, but for chilled water, many people have misunderstanding, many people even think that chilled water is a good disi...
Four common techniques for the removal of dissolved oxygen from water have been examined:boiling at 1 atm, boiling under reduced pressure, purging with N(2) and sonication under reduced pressure. ... Nitrogen purging for 20-40 min at flow rate of 25 mL/s was found to be the most effecti...
Why water is a weak electrolyte? Explain why o-chlorobenzoic acid is insoluble in water, but sodium o-chlorobenzoate is soluble in water Why do hydrolysis reactions occur more readily than condensation reactions? Why do soft drinks have a pH of 3? Explain why water was an appropriate solvent ...
Despite of the major role ascribed to marine dissolved organic matter (DOM) in the global carbon cycle, the reactivity of this pool in the dark ocean is still poorly understood. Present hypotheses, posed within the size-reactivity continuum (SRC) and the
Alan Izhar-Bodner, an Israeli inventor, has developed a way for divers to breathe underwater without cumbersome oxygen tanks. His apparatus makes use of the air that is dissolved in water, just like fish do. (From Breathe like a fish!) ...
