SNC 2D Chemistry Review WHMIS – 1) Draw each WHMIS symbol 2) Identify the symbol’s name 3) write a risk factor associated with it. WHMIS stands for: _______________________________________________________ Differentiate between WHMIS labels: supplier vs. workplace by drawing one of each. State whether each of the following are describing chemical or physical properties or changes. The car is shiny. ____________________ The ice melted. ___________________ The reaction produced bubbles. _________________ The paper was shredded. ________________ A blue precipitate was seen at the bottom of the test tube when the 2 liquids were mixed. _________________ Define each of the terms: Atom Ion Cation Anion Ionic bond Molecular bond Law of Conservation of Mass Corrosion Combustion (complete & incomplete) Periodic Table – be able to identify: halogens, noble gases, alkali earth metals, alkali metals, metals, non-metals, metalloids Bohr Diagram - Draw a Bohr Diagram for each of the following elements: Magnesium Aluminum Carbon Bohr-Rutherford Diagram – Draw a Bohr Rutherford Diagram for each of the following elements: Magnesium Sodium Fluorine Draw Bohr diagrams to show how beryllium and oxygen will react together to form an ionic compound. Use arrows to show electron movement. Draw Bohr diagrams to show how beryllium and fluorine will react together to form an ionic compound. Use arrows to show electron movement. Fossil Fuels What are some common fossil fuels and what do we use them for? What are some of the environmental issues associated with fossil fuels; their production, use and transportation??? Chemical Equations – what is meant by: (aq) (l) (s) (g) Word Equations - write word equations for each of the following Potassium metal and chlorine gas combine to form ________________. _______________________________________________________________________________ Zinc and lead (II) nitrate react to form ______________________. _______________________________________________________________________________ _________________ and __________________ react to form aluminum chloride and bromine gas. _______________________________________________________________________________ Compounds Compound Magnesium bromide Carbon dioxide Is the compound ionic or molecular? How do you know? Write the Formula (What hints did you use to decide if it was molecular or ionic?) (do you need to crisscross?) Phosphorous trichloride Lithium iodide Diphosphorous hexoxide Ionic or Molecular? Formula Ionic or Molecular? Name of the compound (hint: do you need prefixes?) P2O3 CBr4 SCl2 SrCl2 Balanced Chemical Equations What type of reaction is the following? __________________________ Word equation Skeleton equation - need chemical formulas: - should you criss-cross? - for atoms – check the pink sheet to make sure that they can exist by themselves Work – use colours Balanced chemical equation carbon monoxide Carbon + Oxygen What type of reaction is the following? _____________________________ Word equation Skeleton equation - need chemical formulas: - should you crisscross? - for atoms – check the pink sheet to make sure that they can exist by themselves Work – use colours Iron (III) Oxide + Hyrdogen + Iron Water Balanced chemical equation How can you identify each type of reaction? 1) Synthesis (S) ___________________________________________________________________ 2) Decomposition (D) _______________________________________________________________ 3) Single Displacement (SD) _________________________________________________________ ________________________________________________________________________________ 4) Double Displacement (DD) ________________________________________________________ ________________________________________________________________________________ Acids, Bases, Neutralizers Label the pH scale to identify: (use page 272 as a reference) a) acids b) bases f) stomach acid 1 2 3 4 5 c) neutral g) bleach 6 7 d) strong acid h) milk 8 9 e) weak acid i) baking soda 10 11 12 13 14 Acids: what are some characteristics?
