WitrynaTo find out how many moles of water in 3 cups just divide 720 by 18.0015 which gives you 39.9667 moles of water. This gives you 240.685 * 10^32 or 2.40685 * 10^34 water molecules. Since there are 3 atoms in a water molecule multiply the number of water molecules by 3 giving you 7.2206 * 10^34 atoms.

WitrynaAlso, hydrogen bonds are stronger, pickier about distance and angle than the alternatives available to other molecules (dipole-dipole, van der Waals etc.) So even if they seem feeble, and even if the alternatives were as plentiful as hydrogen bonds, the latter would still be more capable of tying up molecules. ionic webstormWitrynaYou answer should include description of the significance of hydrogen bonds to the following: water biological molecules at least one cellular process We don’t have … ionic wall clockWitrynaMost of the hydrogen bonds between compound 1 and the BRI1–BAK1 complex are absent in the complexes formed with the synthetic analogs. However, for compounds … ontarogaWitrynaErnest Zinck. Water has a high surface tension because the water molecules on the surface are pulled together by strong hydrogen bonds. That means a drop of water will "want" to have the smallest possible surface area. The shape that has the smallest possible area for a given volume is a sphere. ionic vs tourmaline vs ceramicWitrynaHydrogen bonding plays a vital role in physiological systems. Proteins contain chains of amino acids. The amino acid units are arranged in a spiral form somewhat like a stretched coil spring (forming a helix).
