CHEM-C 127 Study Guide - Midterm Guide: Observational Error, Standard Deviation, Cleaning Agent
Document Summary
Questions relatively evenly split between 4 experiments. 2-28-16: any kind of calculator allowed, lab notebook allowed, 3x5 note card allowed, sunday 2/28 7:15 q/a review. Calorimetry: be able to calculate specific heat capacities (j/goc) and/or calorimeter constants (j/oc) given the, heat lost by a 100. 0 oc metal = heat gained by water and the calorimeter needed information. (cid:3040)(cid:3047)(cid:3039)(cid:3046) (cid:2869)= (cid:3050)(cid:3047)(cid:3045)(cid:4672)4. (cid:883)84 (cid:4673)(cid:4666) (cid:2870)(cid:4667) (cid:3039) (cid:2870: know how systematic error affects calculated values, like specific heat capacities. Shorter chains = smaller micelle = less room inside the micelle = not much room to trap nonpolar dirt/oil. Allow nonpolar reactants to react in water: the reaction process of making soap. Reactions speed up with increased temperature, slow down with decreased temperature: soaps vs. detergents. Soaps react with hard water, detergents do not.
