What determines the rate at which a molecule of water moves through the cycle, as discussed in the third paragraph? A.The potential energy contained in water.B.The effects of atmospheric pressure on chemical compounds.C.The amounts of rainfall that fall on the continents.D.The relative size ...
信息定位在文章第三段第一句“the rate at which a molecule of water passes throughthe cycle is not random but is a measure of the relative size of the various reservoirs”,由此可知水分子的循环率决定于多种存水库的相对大小,选项D中的water storage areas是the relative size of the variousreservoirs...
A water molecule is composed of two elements: one oxygen atom and two hydrogen atoms. Water is a polar molecule, meaning the electrons are not shared equally between the three atoms. Oxygen has a high electronegativity, or electron-loving, making the oxygen end of a water molecule slightly ne...
How much does a 100 ml beaker weigh? What is the mass in grams of a single molecule of water, H2O? What is the mass of a 15 mL sample of mercury? A substance has a density of 4.5 g/mL. What is this in kg/L? What is the mass in kilograms of one liter of water? What is ...
What kind of molecule is water? What are non-examples of a molecule? What chemical elements are involved in biochemicals? Which elements make up carbohydrates? What is high ionization energy? What kind of bond holds together atoms within a molecule? What property of an atom does binding energy...

Mixturesconsist of two or moredifferent elements and / or compounds- physically intermingled, so Mixturescan include: at least two different types of atoms,or at least two different types of molecules,or at least one type of atomandat least one type of molecule. ...
The micelles aren’t bound together into a molecule, which means they’ll rearrange easily. If the micellar water is poured onto a cotton wool pad, for example, it rearranges so that the heads are stuck to the cotton wool (made of cellulose, which is hydrophilic), and the tails stick ...
Water and the bad smelling molecule hydrogen sulphide do not seem to have a lot in common at first sight. However, when investing a little energy, some differences disappear. At first glance, the ice cube in your soft drink and the smell of grandma’s famous egg salad don’t seem ...
sodium chloride compound particles, without a clear number of atomic nuclei. The same thing is true if you look at a drop of water; you aren’t looking at a molecule of water, but rather a huge grouping of liquid H2O molecules in a high enough concentration to be seen by the naked ...
