Research question/Aim Extract copper from copper oxide by reduction using butane gas Hypothesis The butane gas will reduce the copper oxide and leave behind pure copper. This will allow us to find the empirical formula of the copper oxide as well as the masses of oxygen and copper Variables Dependant variable The dependant variable will be the reduction of the copper oxide which will be calculated at different temperatures. Independent variable The independent variable here

Throughout the data and the observations got from this experiment‚ there are some reasons which may affected the mass of the copper was recovered and also the percentage of yield. According to the law of conservation of matter‚ the mass of the copper will not change even though there are many chemical reactions happened which also mean that the mass of copper contained in solutions or precipitates remain the same as the copper in the beginning. And it is necessary to synthesize the various copper

Analysis of a Hydrated Crystalline Compound Katie Sanders Science Block 3 February 29‚ 2012 Title: Analysis of a Hydrated Crystalline Compound Purpose: The purpose of our experiment was to determine the amount of water in copper sulfate pentahydrate expressed as a percent. Hypothesis: I think that bluestone crystals are 20% water‚ because it’s called pentahydrate (penta means five) and 1/5 of 100 (since it’s expressed as a percent)
