    of basic copper carbonate 〖mCuCO〗_3⋅n〖Cu(OH)〗_2 were observed by changing the reaction mole ratio. The reaction mole ratio of sodium carbonate to copper chloride (II) was controlled from 1.08 to 1.68. Fig. 1 shows the XRD patterns of copper carbonate powder. At a reaction ratio of 1.08, paratacamite (Cu_2 Cl(OH)_3 ), beside alkali copper carbonate, was formed because of incomplete reaction at a copper content of 53.9 wt%. Lack of sodium carbonate may cause incomplete reaction with copper chloride

    Investigation of the Thermal Decomposition of Copper Carbonate Aim: Copper has two oxides, Cu2O, and CuO. Copper carbonate, CuCO3 decomposes on heating to form one of these oxides and an equation can be written for each possible reaction Equation 1: 2CuCO3 (s) Cu2O (s) + 2CO2 (g) + O2 (g) Equation 2: CuCO3 (s) CuO (s) + CO2 (g) The aim of this experiment is to prove which equation is correct. This can be done by volumetric analysis i.e. calculating the volume of gas produced. This is then

    Procedure: A. Reaction between the elements copper and sulfur To begin the lab, a 5 cm copper wire was obtained and observed. Properties such as luster, malleability, and color were noted. Then, a pencil was used to make a small coil by wrapping the copper wire against it. The coil was placed in a crucible afterwards. Sufficient powder sulfur was added in. The crucible was then covered and conscientiously placed upon a clay triangle on an iron ring. Next, the crucible was heated with the hottest

    helium that mostly formed after the big bang. All chemical elements known to mankind are present in the “Periodic Table” that arranges them and summarizes their chemical properties. One of the mostly used chemical elements in life is Copper “Cu” The word copper derives from the Latin “cuprum,” which translates into

    For our copper and sulfur experiment we used a crucible to hold the chemicals while they were heated. We also used a ring stand ring and a triangle to hold our crucible above the fire. A clay triangle was employed to hold the crucible above the bunsen burner’s flame. To take the hot crucible off of the clay triangle crucible tongs were utilized. Procedure A.) A Reaction Between the Elements Copper and Sulfur A 2 inch copper wire was obtained. The first observation of just the copper wire was

    Needed in this experiment will be pennies dated before 1982 because that was when pennies were made of copper. During this experiment, the group will be mixing together different chemical reactions in order to get the penny to turn green. The group is trying to create a patina coating on the penny. Patina is referring to the blue-green layer of corrosion that expands on the surface of copper when it is exposed to oxygen and sulfur compounds. However, instead of using simply sulfur and oxide compounds

    All the chemical elements are given a unique atomic number; copper is the 29 atomic numbers. Atoms are made of three kinds of smaller particles, called protons, neutrons and electrons the atomic number is the number of protons in the atom. Each element is first identified at room temperature and pressure as being solid, liquid or gas therefore copper is a solid. Elements, like copper, have other properties and characteristics physical properties can be observed and measured whereas chemical properties

    Environmental Protection Agency (USEPA) has set its cooper particles allowable points of confinement as 1.3 mg/L in modern effluents. Copper were released from the diverse enterprises, for example, metal cleaning and plating showers, paints and colors, mining, purifying, oil refining, flushes as metal, compost, paper board, wood mash and printed circuit board creation. Moreover, copper is phytotoxic and to be sure, has been utilized as an algaecide to control algal blossoms. An assortment of treatment innovations
