Transcript

  • 1. SAMPLE ONLY SAMPLE ONLY SAMPLE ONLY For FULL presentation click HERE >> www.warnescience.net Stock Notation K Warne Iron (III) oxide Fe3+ O2-
  • 2. SAMPLE ONLY SAMPLE ONLY SAMPLE ONLY For FULL presentation click HERE >> www.warnescience.net Balancing Equations & Stock Notation Different reaction conditions temperature & pressure can often result in different products. This occurs because many elements can have more than one valency as in the following examples. Examples 1. 2Fe + O2  2FeO Iron oxide 2. 4Fe + 3O2  2Fe2O3 Iron oxide 3. Cu + O2  CuO Copper oxide 4. Cu + O2  Cu2O Copper oxide We need a system to distinguish between these compounds.
  • 3. SAMPLE ONLY SAMPLE ONLY SAMPLE ONLY For FULL presentation click HERE >> www.warnescience.net Balancing Equations & Stock Notation We use a system of STOCK NOTATION to name compounds which result from varying valences of certain elements. 1 CaO 3 CuCl2 2 MnCl2 4 MnO2 In order to show the Valency of element (usually an metal) we use roman numerals in brackets after the elements name. Ie FeO - iron (II) oxide. Rename the previous examples. 1. FeO 2. Fe2O3 3. CuO 4. Cu2O Now try and name the following compounds.
  • 4. SAMPLE ONLY SAMPLE ONLY SAMPLE ONLY For FULL presentation click HERE >> www.warnescience.net Stock Notation • Only used for positive valences. • Only used for metals. (NO2 is nitrogen dioxide) • The valencies must add up to the overall charge on the molecule. 1 Ag2O 3 CuS 2 PbBr 4 MnO4 Try and name the following examples.
  • 5. SAMPLE ONLY SAMPLE ONLY SAMPLE ONLY For FULL presentation click HERE >> www.warnescience.net Polyatomic Ions These polyatomic ions are common and must be known. (Name and formula) Ion NAME ION NAME OH- CO3 2- NO3 - PO4 3- MnO4 - NH4 + SO4 2- H3O+
  • 6. SAMPLE ONLY SAMPLE ONLY SAMPLE ONLY For FULL presentation click HERE >> www.warnescience.net Common Substances Containing Polyatomic Ions These polyatomic ions are common and must be known. (Name and formula) NAME FORMULA USE Calcium Carbonate (Marble) Sulphuric Acid Ammonium Nitrate Sodium Hydroxide (Caustic Soda) Potassium Permanganate
  • 7. SAMPLE ONLY SAMPLE ONLY SAMPLE ONLY For FULL presentation click HERE >> www.warnescience.net Naming Substances 1. K2SO4 5. NH4OH 2. PbCl2 6. Na2CO3 3. Ca(OH)2 7. Cu(NO3)2 4.H3PO4 8. FeSO4 Write names for the following substances using stock notation where necessary.
  • 8. SAMPLE ONLY SAMPLE ONLY SAMPLE ONLY For FULL presentation click HERE >> www.warnescience.net Hi - This is a SAMPLE presentation only. My FULL presentations, which contain loads more slides (with all the gaps filled in) as well as other resources, are freely available on my resource sharing website: www.warnescience.net (paste into your browser if link above does not work) Have a look and enjoy!
