Reactions
PUTTING IT TOGETHER: Classifying Chemical Reactions
Purpose: To observe and differentiate between the four different types of chemical reactions. Variables: The independent variables are the sodium chloride, sodium carbonate, magnesium,copper, copper (11) sulfate, silver nitrate, oxygen, lead(11) nitrate, sodium carbonate, copper (11) sulfate pentahydrate. The dependent variables are the chemical reactions that are being looked for. For example decomposition, synthesis, single displacement or double displacement of compounds or elements . Hypothesis: Part 1 : I believe that magnesium burning in oxygen will have synthesis reaction because the magnesium will react with the oxygen in the air forming MGO where before the two elements were separate but with added heat they have been able to become a new compound. Part 2: I believe that when the sodium chloride and silver nitrate are mixed a double displacement reaction will occur, making sodium nitrate and silver chloride because sodium is very reactive and therefore when the two elements react they will be switched with one another. Part 3: I believe that a double displacement reaction will occur when lead (11) nitrate and sodium carbonate mix because the sodium will pull the nitrate compound from the lead and the carbonate will be forced to bond with the lead. Part 4: I believe that a single displacement reaction will occur when copper (11) sulphate and magnesium are mixed because on the activity series magnesium is more reactive than copper and will therefore pull the sulphate away and bond with it. Part 5: I believe that a single displacement reaction will occur when silver nitrate and copper are mixed because on the activity series copper is more reactive than silver and will therefore pull the nitrate away and bond with it. Part 6: I believe that a decomposition reaction will occur when the pentahydrate is heated because the water will have evaporated leaving only copper sulphate without any drops of water in it.
