Chemistry Unit Learning Outcomes


Learning for Success – Chemistry Learning Outcomes
  •        I can describe the evidences that led to the development of the atomic model consisting of protons and neutrons (nucleons) and electrons; i.e., Dalton, Thomson, Rutherford, Bohr
  •        I have an awareness of WHMIS guidelines
  •        I can explain the importance of and need for the IUPAC system of naming compounds, in terms of the work that scientists do and the need to communicate clearly and precisely
  •        I can explain, using the periodic table, how and why elements combine to form compounds in specific ratios (Hint: think valence electron pairs)
  •        I can predict formulas and write names for ionic and molecular compounds using a periodic table, a table of ions and IUPAC rules
  •        I can classify ionic and molecular compounds, acids and bases on the basis of their properties; i.e., conductivity, pH, solubility, state
  •        I can relate the molecular structure of simple substances to their properties (e.g., describe how the properties of water are due to the polar nature of water molecules)
  •        I can use IUPAC rules to name common acids
  •        I can use a solubility chart to predict whether an ionic compound will be soluble or insoluble in water
  •        I can describe evidences for chemical changes
  •        I can differentiate between endothermic and exothermic reactions.
  •        I can determine whether or not photosynthesis or cellular respiration are endothermic or exothermic
  •        I can identify situations where chemical reactions as useful in my house and in industry.
  •        I can balance chemical equations
  •        I can identify and classify the following reactions:
  • o   Formation
  • o   Decomposition
  • o   Hydrocarbon combustion
  • o   Single Replacement
  • o   Double Replacement
  •        I can predict the products of a reaction when given the reactants
  •        I can define the mole
  •        I can interpret chemical equations in terms of moles of chemical species and relate the mole concept to the law of conservation of mass.

Naming Acids

Hi guys,

Sorry for the hiatus from the internet!  I hope you all had a lovely Eid holiday.  Can you believe that there are only 4 weeks left until the winter holidays?  I'll be posting as many resources as I can find that will help you with your upcoming Unit Final.  Don't forget, it's coming up on November 30!

Here is a YouTube video from Brightstorm2 about naming acids.  It goes over the same rules that we did!

Also, you may want to check our BrightStorm2's other videos about naming ionic compounds and molecular (covalent) compounds.

I hope it helps!
