1 Determination of Empirical Formula: Preparation of a Copper Sulphide. Aim The aim of the experiment was to determine the empirical formula of sulphide of copper and to make sure that an amount of copper metal reacted with elemental sulphur‚ Eq. 1. To be able to calculate the empirical formula of copper sulphide‚ the mass (grams) of copper has to be known and the mass (grams) of copper sulphide after the reaction. Copper‚ chemical formula Cu‚ is a known metal with a red-brown

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

experiment‚ we were trying to see whether copper‚ after a chain of chemical reactions‚ will revert back to its elemental form. Procedure: First‚ I added nitric acid with copper in a beaker‚ which turned into a copper nitrate‚ a blue-green solution. Afterwards‚ I added sodium hydroxide‚ and my solution colored to a dark blue solution called copper hydroxide. I heated the solution to evaporate the water and I got a brownish-blackish solid called copper oxide. Once the solid appeared‚ I poured
