  1. 1. Notes
  2. 2.  The student will: Distinguish the difference between achemical and a physical change Investigate and understand physicalchanges in matter Investigate and understand chemicalchanges in matter Investigate and understand chemicalformulas and the types of bonds found insimple compounds
  3. 3. The Law of Conservation ofMass/MatterChemical ChangePhysical ChangeChemical FormulaChemical EquationReactantProduct
  4. 4. States thatmass/matter isneither lost orgained during areaction, thoughit may change insubstance, form,phase or state
  5. 5.  When a substancechanges its size orshape or phase/state ofmatter but still retainsthe properties of theoriginal substance i.e.:▪ Paper being torninto little pieces
  6. 6.  When a newsubstance is createdthrough thecombination ofchemicals or energy i.e.:▪ Paper burning andturning into ash(carbon)
  7. 7. The way asubstance orcompound isexpressedsymbolically▪CO2 is CarbonDioxide▪H2O is Water▪C6H12O6 isGlucose
  8. 8. A math-likeequation thatshows howchemicals arecombinedC + O2CO2▪ means“Yields”
  9. 9. The chemicalscombined in achemicalequationLocated on theleft side of theequationCarbon (C) + 2Oxygen atoms(O2)▪C + O2 CO2
  10. 10. The finaloutcome of achemical reactionLocated on theright side of theequation, (right ofthe yields symbol)C + O2  CO2▪Carbon (C )+ 2Oxygen atoms (O2)= Carbon Dioxide(CO2)
