Question
1. Write a balanced chemical equation for the decomposition ofcopper II sulfate pentahydrate 2. A student heated a hydrated salt sample with an initialmass of 4.8702g. After the first heating, the mass had decreased to3.0662g a) If the sample was heated to constant weight afterreheating, what is the minimum mass that the sample can have afterthe second weighing? Show how you determined your answer b. The student determined that the mass lost by the sample was1.8053. What was the precent water in the original hydratedsample? Show calculation setup 3. If the freezing point of a certain pure substance is 21 C,what is its melting point? 4. What happens to the individual particles in a liquid as aheat is removed? 5. What happens to an individual particles as heat isadded? 6. What happens to the freezing point of a substance whenanother substance is dissolved in it? 7. What is supercooling? 1.
