Putting All of Our Skills Together – WORK PERIOD SNC2D – Chemistry Review The skills you have learned so far in our chemistry unit are… Writing chemical formulas Identify states of matter of various elements and compounds Identifying types of reactions and predicting products based on these types of reactions Balancing equations We are now going to put all of these skills together! Task #1: For each of the following equations, which are to be answered on a lined piece of paper… a) b) c) d) e) f) g) h) i) j) k) Convert each element/compound name to a chemical formula Identify the states of matter for each element and compound in the equation Identify the type of reaction that is taking place Balance the equation. Sodium sulphate + hydrogen chloride sodium chloride + hydrogen sulphate Tin(IV) chloride + water tin(IV) oxide + hydrogen chloride Iron + hydrogen sulphate iron (III) sulphate + hydrogen gas Methane gas + oxygen gas carbon dioxide + water Potassium nitrate + sodium carbonate potassium carbonate + sodium nitrate Ammonium sulphate + lead (IV) nitrate ammonium nitrate + lead (IV) sulphate Selenium hexachloride + oxygen gas selenium dioxide + chlorine gas Copper + oxygen gas copper (II) oxide Sodium chloride sodium + chlorine gas Potassium sulphate + barium chloride potassium chloride + barium sulphate Calcium hydroxide + ammonium chloride calcium chloride + ammonium hydroxide Task #2: For each of the following equations, which are to be answered on a lined piece of paper… Identify which type of reaction would most likely take place, given your reactants Predict the products of the given reaction Identify the state of matter for each element/compound in the equation Balance the equation. a) Pb(NO3)2 + NaI b) Ag + Cl2 c) Zn + H2SO4 d) Fe2O3 e) Rb + O2 f) Sr + CuSO4 g) N2O5 h) Ca + N2 i) Al + O2 j) C3H8 + O2 Take #3: Find the mistake in each of the following solutions. a) Write the skeleton equation and state the type of reaction for lead(II) chloride + Potassium b) Mg2 (s) + 02 (g)
