2. Part 1 3.Yes 5. C 25 H 52 + 38O 2 25CO 2 + 26H 2 O Part 2 8. 2C 2 H 2 + 5O 2 4CO 2 + 2H 2 O 9. Complete: 1/10, Incomplete: 1 11. Black deposit/product 12. Yes Questions 1. H 2 O and CO 2 2. C, CO, CO 2, H 2 O (always produced) 3.Carbon (C)

3. 4.All of the oxygen would be used up & some excess hydrogen will remain. This is different from a hydrocarbon because only H 2 O can form, not HO or H (vs. C or CO rather than CO 2 ). 5.C 3 H 8 + 5O 2 3CO 2 + 4H 2 O 6. 2C 3 H 8 + 9O 2 2CO + 4CO 2 + 8H 2 O C 3 H 8 + 4O 2 2CO + CO 2 + 4H 2 O 2C 3 H 8 + 5O 2 2CO + 4C + 8H 2 O C 3 H 8 + 3O 2 2CO + C + 4H 2 O
