### Stoich easy ratio calcs

1. 1. Rusty rust rusting
2. 2. This is the equation for IRON rusting …. 4Fe + 3O2 --> 2Fe2O3
3. 3. What does it mean?????????4Fe + 3O2 --> 2Fe2O3
4. 4. It means that … 4Fe + 3O2 --> 2Fe2O34 atoms + 3 molecules make 2 FUOf IRON of oxygen of RUST
5. 5. OR in moles it means… --> 2Fe O 4Fe + 3O2 2 34 mole Fe + 3mole O2 make 2 mole rust
6. 6. OR 4Fe + 3O2 --> 2Fe2O34 mole Fe + 3mole O2 make 2 mole rust224 grams + 96 grams make 320 gramsIron oxygen of rust
7. 7. 4Fe + 3O2 --> 2Fe2O34 mole Fe + 3mole O2 make 2 mole rust224 grams + 96 grams make 320 gramsIron oxygen of rust
8. 8. 4Fe + 3O2 --> 2Fe2O34 mole Fe + 3mole O2 make 2 mole rust224 grams + 96 grams make 320 gramsIron oxygen of rust
9. 9. 4Fe + 3O2 --> 2Fe2O34 mole Fe + 3mole O2 make 2 mole rust224 grams + 96 grams make 320 gramsIron oxygen of rust
10. 10. 4Fe + 3O2 --> 2Fe2O34 mole Fe + 3mole O2 make 2 mole rust224 grams + 96 grams make 320 gramsIron oxygen of rust
11. 11. 4Fe + 3O2 --> 2Fe2O34 mole Fe + 3mole O2 make 2 mole rust224 grams + 96 grams make 320 gramsIron oxygen of rust
12. 12. 4Fe + 3O2 --> 2Fe2O34 mole Fe + 3mole O2 make 2 mole rust224 grams + 96 grams make 320 gramsIron oxygen of rust
13. 13. 4Fe + 3O2 --> 2Fe2O34 mole Fe + 3mole O2 make 2 mole rust224 grams + 96 grams make 320 gramsIron oxygen of rust
14. 14. 4Fe + 3O2 --> 2Fe2O34 mole Fe + 3mole O2 make 2 mole rust224 grams + 96 grams make 320 gramsIron oxygen of rust
15. 15. 4Fe + 3O2 --> 2Fe2O34 mole Fe + 3mole O2 make 2 mole rust224 grams + 96 grams make 320 gramsIron oxygen of rust
16. 16. 4Fe + 3O2 --> 2Fe2O34 mole Fe + 3mole O2 make 2 mole rust224 grams + 96 grams make 320 gramsIron oxygen of rust
17. 17. 4Fe + 3O2 --> 2Fe2O34 mole Fe + 3mole O2 make 2 mole rust224 grams + 96 grams make 320 gramsIron oxygen of rust
18. 18. 4Fe + 3O2 --> 2Fe2O34 mole Fe + 3mole O2 make 2 mole rust224 grams + 96 grams make 320 gramsIron oxygen of rust
19. 19. 4Fe + 3O2 --> 2Fe2O34 mole Fe + 3mole O2 make 2 mole rust224 grams + 96 grams make 320 gramsIron oxygen of rust
20. 20. 4Fe + 3O2 --> 2Fe2O34 mole Fe + 3mole O2 make 2 mole rust224 grams + 96 grams make 320 gramsIron oxygen of rust
21. 21. 4Fe + 3O2 --> 2Fe2O34 mole Fe + 3mole O2 make 2 mole rust224 grams + 96 grams make 320 gramsIron oxygen of rust
22. 22. 4Fe + 3O2 --> 2Fe2O34 mole Fe + 3mole O2 make 2 mole rust224 grams + 96 grams make 320 gramsIron oxygen of rust
23. 23. 4Fe + 3O2 --> 2Fe2O34 mole Fe + 3mole O2 make 2 mole rust224 grams + 96 grams make 320 gramsIron oxygen of rust
24. 24. 4Fe + 3O2 --> 2Fe2O34 mole Fe + 3mole O2 make 2 mole rust224 grams + 96 grams make 320 gramsIron oxygen of rust
25. 25. 4Fe + 3O2 --> 2Fe2O34 mole Fe + 3mole O2 make 2 mole rust224 grams + 96 grams make 320 gramsIron oxygen of rust
26. 26. 4Fe + 3O2 --> 2Fe2O34 mole Fe + 3mole O2 make 2 mole rust224 grams + 96 grams make 320 gramsIron oxygen of rust
27. 27. 4Fe + 3O2 --> 2Fe2O34 mole Fe + 3mole O2 make 2 mole rust224 grams + 96 grams make 320 gramsIron oxygen of rust
