Presentation Transcript

  1. Chemical Reactions By Mr Hem

  2. Compound Ions Wants to give one electron • Ammonium NH41+ • Hydrogen Carbonate NCO3 1- • Hydroxide OH1- • Nitrate NO3 1- • Carbonate CO3 2- • Sulfate SO3 2- • Phosphate PO3 3- Wants to gain one electron What about the rest?

  3. Chemical Formulas for Ionic Compounds Na 1+ Cl 1- • 1 + 1- = 0 • NaCl Al 1+ O 2- • 2 x 1+ 2- • 2+ 2- = 0 • Al2O Boron 3+ Sulfide 2- • 2 x 3+ 3 x 2- • 6+ 6- = 0 • B2S3 2 x 2 x 3 x

  4. Work (put in diary) • 2.2 page 33 question 1 to 7 • 2.3 page 37 question 1 to 8

  5. Chemical Equations Sodium Hydroxide + Hydrochloric Acid  Sodium Chloride + Water Na0H+ HCl  NaCl + H20 Reactants Products Reactant Ions Swap Partners They must be balanced – Due to law of conservation -Atoms cannot just appear or reappear!

  6. The Famous Reaction • Carbon Dioxide + Water  Oxygen Gas + Glucose Photosynthesis!!! C02 + H20  02 + C6H1206 Needs to be balanced!!!! c o 6 6 6 o h o o o h

  7. Another Example • Propane C3H8+ Oxygen Gas  Carbon Dioxide + Water

  8. Activity on page 39? • I don’t have smarties • I do have modelling clay • and cameras!
