1. Chem-To-Go Lesson 22 Unit 5 PREDICTING PRODUCTS OF HYDROCARBON COMBUSTION, SINGLE REPLACEMENT, AND DOUBLE REPLACEMENT REACTIONS

2. PATTERN: CxHy + O2  CO2 + H2O SAME PRODUCTS EVERY TIME Combustion of Hydrocarbon PATTERN: A + BX  AX + B USE ACTIVITY SERIES Metal replaces other metal. Single Replacement of Metals PATTERN: Y2 + BX  BY + X2 USE ACTIVITY SERIES Halogens are diatomic! Single Replacement of Halogens PATTERN: AX + BY  AY + BX IONS SWITCH PARTERS Criss-cross every compound. Double Replacement USING PATTERNS TO PREDICT

3. Example: Write a chemical equation for the combustion of carbon tetrahydride. COMBUSTION OF HYDROCARBON

4. Example: Write a chemical equation for iron reacting with nickel (II) chloride. SINGLE REPLACEMENT OF METALS

5. Example: Write a chemical equation for chlorine reacting with strontium bromide. SINGLE REPLACEMENT OF HALOGENS

6. Example: Write a chemical equation for lithium dichromate reacting with aluminum nitrate. DOUBLE REPLACEMENT
