Lecture 12.1- Interpreting Balanced Equations
- 6. N 2 (g) + 3H 2 (g) 2NH 3 (g) 2 N + 6 H = 2 N + 6H Atoms are conserved!!
- 7. Coefficients tell us the RATIO of molecules N 2 (g) + 3H 2 (g) 2NH 3 (g)
- 8. Coefficients tell us the RATIO of molecules one N 2 + three H 2 two NH 3 molecule molecules molecules N 2 (g) + 3H 2 (g) 2NH 3 (g)
- 9. Coefficients tell us the RATIO of moles N 2 (g) + 3H 2 (g) 2NH 3 (g)
- 10. one mole + three moles two moles N 2 H 2 NH 3 Coefficients tell us the RATIO of moles N 2 (g) + 3H 2 (g) 2NH 3 (g)
- 11. Find the molar mass of each compound & multiply by the coefficient N 2 (g) + 3H 2 (g) 2NH 3 (g)
- 12. 28g + 3 x 2g 2 x 17g N 2 (g) + 3H 2 (g) 2NH 3 (g) Find the molar mass of each compound & multiply by the coefficient
- 13. 28g + 3 x 2g 2 x 17g Why do you multiply the molar mass by three? N 2 (g) + 3H 2 (g) 2NH 3 (g) Find the molar mass of each compound & multiply by the coefficient
- 14. 28g + 3 x 2g 2 x 17g 28g + 6g 34g N 2 (g) + 3H 2 (g) 2NH 3 (g) Find the molar mass of each compound & multiply by the coefficient
- 15. 34g = 34g Mass is conserved! 28g + 3 x 2g 2 x 17g 28g + 6g 34g N 2 (g) + 3H 2 (g) 2NH 3 (g) Find the molar mass of each compound & multiply by the coefficient
- 16. N 2 (g) + 3H 2 (g) 2NH 3 (g) At STP, one mole of gas occupies 22.4 liters.
- 17. 22.4L N 2 + 3 22.4L H 2 2 22.4L NH 3 N 2 (g) + 3H 2 (g) 2NH 3 (g) At STP, one mole of gas occupies 22.4 liters.
- 18. N 2 (g) + 3H 2 (g) 2NH 3 (g) At STP, one mole of gas occupies 22.4 liters. 22.4L N 2 + 3 22.4L H 2 2 22.4L NH 3 22.4L 22.4L 22.4L 22.4L 22.4L 22.4L
- 19. N 2 (g) + 3H 2 (g) 2NH 3 (g) At STP, one mole of gas occupies 22.4 liters. 22.4L N 2 + 67.2L H 2 44.8L NH 3 22.4L N 2 + 3 22.4L H 2 2 22.4L NH 3 22.4L 22.4L 22.4L 22.4L 22.4L 22.4L
