C2HeO + O2 (9) - CO2 (a) + Directions: Add 2 ml of a saturated calcium acetate solution to an evaporating dish. To the dish add 15 ml of ethanol and swirl the contents. Pour off any excess liquid and ignite the remaining contents with a match. Sprinkle some boric acid on the flame. Although the reaction is actually more complex, the reaction you will balance and classify is the reaction between only ethanol (C,HSOH) and oxygen. Observations:
