WebApr 9, 2024 · Some examples of hydrogen bonding are as follows. 1. Water. A water molecule is composed of a highly electronegative oxygen atom linked to the hydrogen atom. The electrons of the shared pair are attracted more by the oxygen atom, and this end of the molecule becomes negative, and the hydrogen atoms become positive. In a hydrogen bond, the electronegative atom not covalently attached to the hydrogen is named the proton acceptor, whereas the one covalently bound to the hydrogen is named the proton donor. While this nomenclature is recommended by the IUPAC, in the hydrogen bond donor, the H center is protic. The donor is a Lewis base. Hydrogen bonds are represented as H···Y system…
WebTo 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.
