CHEN 2001 Lecture Notes - Lecture 9: Trihydrogen Cation, Moodle, Integrating Factor
Document Summary
Moodle access overhead hw, recitation, supplemental materla, grade. Homework: due at beginning of lecture (needs name, id, recitation section) can be typed or handwritten, can write on both sides of paper. Our goal in this class is to write mass and energy balance equations; these are the basic tools for engineering analysis of chemical process. 1. 1 goals for a chemical process: (a) make a product with specific functions, (b) want to convert waste into useful materials (ex: corn fiber ethanol, (c) convert material to energy (ex: gasoline in a car) 1. 2 raw materials (air, water, crude oil, minerals, agricultural/waste products (corn)) 1. 3 balance chemical equations: aa + bb cc + dd, ex: c3h8 + 5o2 3co2 + 4h2o, ex: sicl4 + h2 si + 2hcl, define vi = stoichiometric coefficient for species i. If it is 0, then it isn"t in the rxn: ehi = # atoms of element h in i.
