14 sie 2013 · The document discusses several copper-containing proteins including plastocyanin, copper amine oxidase, hemocyanin, cytochrome c oxidase, tyrosinase, and superoxide dismutase. It describes their structures, catalytic functions, and roles in electron transfer reactions and oxidation processes in photosynthesis, respiration, and melanin production.
4 wrz 2016 · Copper is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. It has two stable isotopes and exists in native and mineral forms, with the most important ores being sulfides, oxides, and carbonates.
6 gru 2017 · • Blocks of blister copper are used as anodes and thin sheets of pure copper act as cathodes. • The cathode plates are coated with graphite in order to remove depositing copper. • The electrolyte is copper sulfate (CuSO4) mixed with a little amount of H2SO4 to increase the electrical conductivity.
29 lut 2008 · This demonstration involves some fantastic chemistry and makes an excellent introduction to the use of quantitative calculations to find the formula of a reaction product, copper sulfide. Students will also get the chance to see some of the allotropes of sulfur.
Solid iron (III) sulfide reacts with gaseous hydrogen chloride to form iron (III) chloride and hydrogen sulfide gas. Nitric acid dissolved in water reacts with solid sodium carbonate to...
In this experiment students study the behavior of copper in sulfur vapor, a piece of sulfur is heated and a picece of copper is held in the vapor in a test tube. The copper and sulfur combine to a new substance, which can be recognized from the change in color, density and other properties.
Presentation Transcript. Reaction Types. Combination (Synthesis) Reactions Two or more substances combine to form a new compound. A + X AX • Reaction of elements with oxygen and sulfur • Reactions of metals with Halogens • Reactions with Oxides • There are others not covered here!
