Copper electrodes

The negative electrode is zinc, and the positive electrode is manganese dioxide. In the battery, potassium hydroxide is the electrolyte. When you put this together to create an equation for battery discharge, you get Zn + MnO2 + H2O = ZnO + Mn(OH)2. When battery energy is used, negative

what mass of Copper would be expected and what is the limiting reagent? C. 2.26 g Cu D. Fe 3. If Iron (II) Sulfate were formed, what mass of Copper would be expected and what is the limiting reagent? E. 2.8 g Cu F. CuSO4 Driving Question: What compound is formed when you add 7 g of CuSO4 to 2 g of Fe? Goal: To correctly identify what compound is formed and how close it is to the theoretical yield. Materials: * Safety Goggles

classified as a single gene defect that occurs as a result of a mutated protein. What happens specifically is that there is an abundance of copper, which spreads to different parts of the body such as the liver and the brain. As we know, the liver and the brain are two incredibly important organs in our body, which play a crucial role in how we operate. Therefore the copper has a significant detrimental impact on my overall health and well being. Before I was given the official diagnosis by the doctor

Copper            Copper is a mineral. it is not a plant or a animal. Copper is a metallic metal. It can never be broken down into differnet substances by normal chemical means. Copper was one of the first metals known to humans. People liked it because in it’s native condition, it could easily be beaten into weapons or tools. Copper has been one of the most useful metals for over 5000 years. Copper was probably used around 8000 B.C by

Scientific investigation has been a powerful tool in discovering the truth about the Iceman, especially with the advancements of technology, which have proved to be significant in developing our understanding of theories, both old and new, and allowing a reinterpretation of different aspects of the Otzi’s life. In particular, the extensive studies that have been conducted on the Iceman’s health have considerably shed light on the state of his well-being. This has led to the discussion of the nature

Experiment 8: The Copper Cycle Purpose The main goal of this experiment was to observe series of reactions that convert a piece of copper metal, via several different copper-containing compounds, back into its original elemental form. The data collected was the striking color changes along with their relevant chemical equations. The data was collected while keeping a close eye on the experiment the whole time. The data recorded was used to see the different changes involved with a piece of copper metal. The

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
