  1. SNC2D Review Garside Spring 2012

  2. Discussion Regarding Reactions Lab • You need to remember your 7 Diatomic Elements! • Be sure to put brackets around your polyatomic ions when in a compound – Example: Mg(OH)2 • You do not need to use the crisscross rule for molecular formulas!! Remember – covalent bonds! • Remember to include roman numerals in the names of multivalent compounds

  3. What Will I Be Given on Friday? • Solubility Chart • Periodic Table What Will I Need to Memorize? • Polyatomic Chart (Table 3) • The 7 Diatomic Elements

  4. Instructions: • Write your answers to the following questions on a lined piece of paper. • You can use ALL of your notes to help you. • After every 10 questions, I will post the answers. You will have an opportunity to mark / correct your work before we move on to the next 10. • We will only go through one round TODAY • Once the activities are over, you will have an opportunity to choose a worksheet or textbook questions to work on for the remainder of the period based on your needs.

  5. ROUND 1: Ready?? Set?? Go!!!!!!

  6. Question #1 How many atoms are found in [ 2 MgCO3 ] ? Question #2 List the 7 Diatomic Elements

  7. Question #3 Write the formula for hydrobromic acid Question #4 What are the reactants and products of every neutralization reaction?

  8. Question #5 What is the opposite reaction of Decomposition? Question #6 Name the 6 different types of chemical reactions

  9. Question #7 Write the balanced equation, including states, for the following: When HBrreacts with Mg(OH)2,a neutralization reaction occurs

  10. Question #8 What gases are the main causes of acid precipitation? Question #9 What are the products of every combustion of hydrocarbon reaction?

  11. Question #10 What ion charge does permanganate have?

  12. Answers to Round 1: 10 atoms 2. Hydrogen, Nitrogen, Oxygen, Fluorine, Chlorine, Bromine, Iodide 3. HBr 4. Reactants = Acid and Base Products = Salt and Water 5. Opposite of Decomposition is Synthesis 6. Synthesis, Decomposition, Single Displacement, Double Displacement, Combustion of hydrocarbon, combustion of metals or non-metals

  13. Answers to Round 1: 7. 2 HBr (g) + Mg(OH)2 (s)  MgBr2 (s) + 2 H2O (l) 8. The two main gases are sulphur dioxide and any nitrogen oxide in the atmosphere 9. Carbon dioxide and water 10. Permanganate (MnO4) has an ion charge of 1-
