CHEM 1061 Lecture Notes - Propene, Chlorate, Trisodium Phosphate
Document Summary
Tends to start w/ 1 reactant simpler substances. Tend to form common simple substances as products; ex: n2, h2o, co2, simple salts. Key words: something starts it: heated , catalyst , current . Ex: a sample of limestone containing calcium carbonate is heated: caco3 co2 + cao, *ap: nothing above arrow = graded, rule: carbonates always decompose into co2 and what"s left over. Memorize (mem): ammonia is electrically decomposed: 2nh3 n2 + 3h2 (above arrow = lightening bolt) Even if wrong reaction"s balanced, still get point (pt. ) for balancing. Mem: chlorates always form simple salt + o2: ex: potassium chlorate is strongly heated, 2kclo3 2kcl + 3o2. *ap: states of matter for the reaction not counted unless stated in the problem. Mem: hydrogen peroxide is decomposed: 2h2o2 2h2o + o2. Each element in reactant combines w/ o2. Key words: burned , reacted in o2 , air = o2.
