Double Replacement Prediction Date
Identification from Reactants Two compounds –Note if both anions are the same (oxide), then it is probably a combination reaction! Dont let me trick ya!!!
Prediction of Products Switch the anions –Or cations if you prefer Outsides together and insides together –Like FOIL!
Iron (III) hydroxide + phosphorous acid Fe(OH) 3 + H 3 PO 3 FePO HOH
Ammonium nitrate and barium hydroxide NH 4 NO 3 + Ba(OH) 2 NH 4 OH + Ba(NO 3 ) 2 DEMO
Aluminum sulfide + hydrochloric acid Al 2 S 3 + 6HCl 2AlCl 3 + 3H 2 S
Acetic acid and sodium bicarbonate. HC 2 H 3 O 2 + NaHCO 3 H 2 CO 3 + NaC 2 H 3 O 2 DEMO
Homework Time Complete reaction prediction I ID rxn type FIRST Then LOOK at those notes to help you predict the products. Balance Charges Balance the Reaction
