Document Summary
Low carbon abundance in seawater and earth crust, in comparison to in humans. Silicon is more abundant in the earths crust than in humans and seawater. Silicon has weaker bonds and thus release less energy; oxidized silicon is insoluble in water. Atp (& dna, rna); nucleotide (triphosphate, carbohydrate ribose, double ring structure) Krebs cycle; occurs in the mitochondria of a cell. Ionic electron donated creating positive and negative charged particles. Metallic cloud of shared electrons (form of covalent) Hydrogen bonds special dipolar bond (both permanent) Dipolar bonds permanent and induced dipoles. Dispersion forces - instantaneous and induced, non-polar and uncharged (van der. Emulsifier; has to be a polar and non-polar compound to allow a polar and non-polar compound to mix. Increased temperature increases the rate of a system. Hydrophobic molecules (i. e. fats) can"t interact with water. Brownian motion; movement of gas and fluid particles that occur due to temperature, vital energy source for life as it initiates chemical interactions.
