Document Summary
Scienti c study: observations, ask questions, make hypothesis, make predictions, test predictions, analyze + interpret results. 2: peer review, grants and funding, repeatability, consensus, and theories. Ionic: transfer electrons(lose/gain: table salt: nacl -> na+ cl- Air, blood, crude oil: hydrogen bond: oxygen strongly attracted to 2 hydrogen atoms in. H2o while weakly attracted to hydrogen atoms of another h2o molecule. H2o is key: wide temperature range: 0*-100*c. Strong cohesion: uidity allows transportation of chemicals such as nutrients and waste: high heat capacity: stabilize eco-systems during times of rapid change. Ice less dense than water: due to spacious crystal lattice bonds, results is insulation that prevents water below the ice from freezing. Bonds well with other polar molecules: universal solvent. Transparency to light: allows for photosynthesis ph scale. Aqueous solutions(h2o) dissociate into hydrogen ion(h+) and hydrogen oxide ion(oh-: more h+ = higher acidity. Compounds: organic: carbon atoms joined by covalent bonds(must have carbon-carbon molecule)
