BMS 300 Study Guide - Final Guide: Lipid Bilayer, Gerridae, Sodium Chloride
Document Summary
Water: 2 hydrogen 1 oxygen, h2o, hydrogens partial positive charge, oxygen partial negative charge. Hydrogen bonding: not nearly as strong as sharing of electrons(like o to h, not permanent. Not enough energy 0 c molecules cease switching = ice. A lot of energy 100 c molecules switch frequently = gas. Water strider with detergent in water: boiling points are affected by whether not the molecules have covalent or hydrogen bonds. Ion solubility in water: cations: na+, k+, cs2+, ms2, anions: cl_, hco3, dipole: negative usually interacts with positive. When na+ is mixed with h2o and na bonds with the partial of o: hydrophillic = water loving, hydrophobic = water fearing (avoiding, ex. Beaker with 1 lt. of water and a block of 5. 84 g of sodium chloride. To get moles of this solution, divide liters of water by grams of nacl l/g=moles: describing a rate of diffusion = entropy.
