If water is too warm, there may not be enough oxygen in it. When there are too many bacteria or aquatic animal in the area, they may overpopulate, using DO in great amounts. Oxygen levels also can be reduced through overfertilization of water plants by run-off from farm fields containing...
On the molecular level, water is comprised of water molecules, made up of two hydrogen atoms and an oxygen atom. 在分子层级上,水是由水分子组成的,水分子由两个氢原子和一个氧原子构成。 As liquid water, these molecules are engaged in a constant and random square dance that is called the hyd...
Discuss why water will always move from a hypotonic solution to a hypertonic one if the membrane is permeable to water. This process is the breakdown of glucose into 2 Pas: ___ Why does emulsification have to happen before digestion? Describe how a polysaccharide can make its way in the fo...
and the lining in our lungs is adapted to handle air rather than water. However, there have been experiments with humans breathing other liquids, like fluorocarbons. Fluorocarbons can dissolve enough oxygen and our lungs can draw the oxygen out -- see the last...
As we learned inThe Mole, water is a polar molecule with partial positive charge on each hydrogen atom and partial negative charge on the oxygen atom. This polarity is shown in the following figure: Figure 14.1Water is a polar covalent molecule that's good at dissolving polar solids. ...
You see, the ocean produces a lot of the oxygen we breathe, and it helps regulate the weather and climate. It's like the ocean is the Earth's big air conditioner! Scientists use special underwater vehicles and robots to explore the deepest parts of the ocean. They've discovered amazing ...
To understand why alkanes do not dissolve in water but do dissolve in benzene, we can break down the explanation into a few key steps:Step 1: Understand the Nature of Alkanes Alkanes are hydrocarbons, which means they are compo
Why is aniline soluble in aqueous HCl whereas acetanilide is not? Explain why you can dissolve Ni(OH)2 in aqueous ammonia. Why are alcohols soluble in water sometimes, but not as the carbon chain grows longer? Explain why the solubility of oxygen is lower in water. ...
Kids: So then she doesn't get any, um, seawater in her mouth? Yeah. Is that how you breathe? Katharina: Yes. These tanks are full of air, so I can spend a long time underwater looking at the coral reef. Kids: Can you see salt down there?
Carbon dioxide is highly soluble in water, making it the most soluble of the common, non-toxic gases with high solubility. In perspective, around 1.5 liters of carbon dioxide can dissolve in 1 liter of water at normal atmospheric pressure. ...
