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

Copper and Molybdenum Deposits in the United States Copper and molybdenum resources were not recognized as valuable commodities until economic needs demanded the collection and processing of these minerals in large amounts. The most expansive deposits of copper and molybdenum occur in massive low grade ores and are found in intrusive porphyry formations‚ although many smaller sized but higher grade ores are located in non-porphyry areas. The nation has abundant domestic copper ore reserves but
