A fat molecule, such as a triglyceride, consists of two main components—glycerol and fatty acids. Sodium transfers one of its valence electrons to chlorine, resulting in formation of a sodium ion (with no electrons in its 3n shell, meaning a full 2n shell) and a chloride ion (with eight electrons in its 3n shell, giving it a stable octet). Endothermic reactions absorb more energy than they release. Carbon contains four electrons in its outer shell. I have tried to include as many visuals as possible to help with the understanding of each concept. Chemistry of Life - What is Chemistry of Life?

Atoms, Ions, and Molecules (2. A change of one unit on the pH scale represents a change in the concentration of hydrogen ions by a factor of 10, a change in two units represents a change in the concentration of hydrogen ions by a factor of 100. The chemistry of life answer key. Hydrogen bonds also give water its unique properties, which are necessary for life. Oxygen is a much more electronegative atom than hydrogen, meaning that it attracts shared electrons more strongly, so the oxygen of water bears a partial negative charge (has high electron density), while the hydrogens bear partial positive charges (have low electron density). The albumin protein in the liquid egg white is denatured when placed in a hot pan, changing from a clear substance to an opaque white substance.
As the motion increases, energy is higher and thus temperature is higher. Bonds break and form during chemical reactions. The strands are formed with bonds between phosphate and sugar groups of adjacent nucleotides. Fig Structural formula of a saturated fat molecule Stearic acid, a saturated fatty acid (a) Saturated fat Structural formula of an unsaturated fat molecule Oleic acid, an unsaturated fatty acid (b) Unsaturated fat cis double bond causes bending. Some textbooks use the term "van der Waals forces" to refer only to London dispersion forces, so make sure you know what definition your textbook or teacher is using.
