Water molecules areloosely bound together by weak hydrogen bonds, which gives water its liquid property. ... There are 5 water molecules, each consisting of one oxygen atom (red ball) and two hydrogen atoms (white balls). The bonds holding the H2O molecules together are weak hydrogen bonds. ...
Most macromolecules are made from single subunits, or building blocks, called monomers. The monomerscombine with each other via covalent bonds to form larger moleculesknown as polymers. In doing so, monomers release water molecules as byproducts. ... In the process a water molecule is formed. ...
crystal, average B factor of the protein atoms, percentage of amino acid residues in loops, average solvent-accessible surface area of the amino acid residues, grand average of hydropathy of the protein(s) in the asymmetric unit and normalized number of heteroatoms that are not water molecules....
How many water molecules can fit in a 250 mL cup of water, H_2O at 4°C?(Assume the density of water is 1.00 g/mL at 4°C)SETUP: (Hint Convert the mass of water to molecules.) 相关知识点: 试题来源: 解析 83.64* 12^(23) molecules ...
How many moles of carbon dioxide molecules are produced when 1 mole of ethanol is combusted? What mass of water is produced from the complete combustion of 65.0 grams of propane? What mass of water is produced from the complete combustion of 28.0 grams of propane?
Why are carbon atoms important in organic molecules? Why are water molecules partially charged? Why does water need a specific type of bond in the body? Why do ionic compounds dissolve readily in water? Why are coordination compounds important?
aWater molecules have no memory, and therefore it is silly to talk about the number of times that the water you drink has been polluted and repurified, as if the molecules gradually wore out. All that is important is how pure it is when you drink it. 水分子没有记忆,并且谈论水您喝被...
How many water molecules are in 5 moles of water? If you have 4.86 x 1022 molecules of water, how many moles of water do you have? How many moles are in 3.5 x 10^{24} molecules of water? 2C_2H_6(g) + 7O_2(g) \rightarrow 4CO_2(g) + 6H_2O(g) How many moles of wat...
Two water molecules were found in the first hydration shell of the ligand: one molecule was above the ligand plane and another was below it. Each water molecule forms mobile hydrogen bonds with the 18-crown-6 molecule; i.e., the O atom of the water molecule is localized above the ligand...
Molecules are made up of atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among atoms.
