Read the Voltmeter to see what the electrical cell potential is. Repeat steps 13-18 for all variations of Copper Chloride. Record the raw quantitative data in the table below: Electrical Potential Difference Between Zinc and Copper Solutions Electrical Potential Difference Variation in Copper Chloride Trial 1 Trial 2 Trial 3 0.5 1 1.5 2 2.5 Record qualitative data as well in the Observations section. When all quantitative data has been collected and recorded, use the equation

Zink (Biological Anthropologist) worked as the lead examiner of the Iceman and as the head of the Institute for Mummies and the Iceman. According to the documentary: When Dr. Gostner found the arrowhead, it implied the Iceman had died by murder. The copper axe found on the Iceman implied that the Stone Age was much earlier than what was believed. Blood found in the Iceman’s brain implied a head blow before dying

Introduction: This experiment is based on determining the chemical formula for a hydrated compound containing copper, chloride, and water molecules in the crystal structure of the solid compound, using law of definite proportion. The general formula of the compound is CuxCly•zH2O, and aim is to determine chemical formula of this compound. Law of definite proportion, sometimes called Proust’s law, states that a compound always has exactly the same proportion of elements by mass. This

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

reaction and copper appears. The reaction that occurred between Copper (II) Chloride and aluminum was a single replacement reaction. Clear signs that a chemical reaction took place include heat release/temperature change, color change, and formation of a precipitate. When a single element, in this instance aluminum, replaces another element in a compound, copper, a single replacement reaction occurs. A basic formula for these reactions is AB + C → AC + B. The reaction between Copper (II) Chloride

Copper is a chemical element that has the symbol Cu and atomic number 29 (Copper Development Association of South Africa, 2017). The element possesses a wide range of properties that make it invaluable for many different applications. It is an excellent conductor of heat and electricity, as well as being very malleable and ductile. Copper also has excellent alloying properties and is resistant to corrosion (Geoscience Australia, 2017). Copper mining is a large industry in Australia, but the industry

Pennies made before 1982 and the pennies that were made after them create a significant difference. Pennies made before 1982 are made of copper (Warnick 1). Due to the change of the of the metals over the time period it must of caused a change in the pennies mass. Therefore, the density of pennies created before 1982 and the pennies produced today have different densities. Density can also be used to identify unknown substances“Density is defined as the ratio of mass to volume” (Lab: A Penny For

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

the element copper. Copper is one of the first metals ever to be handled by human hands and till this day is still one of the most important metals in the industry. Copper gets its name from the Latin word “Cuprum” this words meaning is from the island of Cyprus. Cyprus is an island where the Romans mined for copper in the ancient times. Copper is an transition metal with the atomic number twenty nine. Copper has an atomic weight of sixty three point five hundred and forty six. Copper has a density

PolyMet Mine PolyMet is planning on mining for copper, nickel, and cobalt in northeast Minnesota. PolyMet will be mining in an area of 6,650 acres which they will be exchanging with The Forest Service for 6,690 acres of PolyMet’s land. There mining operation will go on for 20 years and will process 225 million tons of ore. The project will employ 360 people directly and around 600 people indirectly, and will have an estimated earnings of $515 million annually. Ones they have the correct permits
