On the periodic table of elements, copper is situated next to nickel and zinc in the first row of what is called transition metals, which refer to metallic metals with certain properties. These properties include being good conductors of electricity, being resistant to corrosion, being very mall...
In carboxypeptidase A, how does the zinc ion help catalyze the reaction? Explain in detail. If a nickel rod embedded in a silver nitrate solution, what do we predict? explain. Why is magnesium sulfate used to clean up a lead nitrate spill? What can be used to recover copper from a copp...
Austenitic stainless steels such as 304 or 316have high amounts of nickel and chromium. The chromium combines with the oxygen before the iron is able to which forms a chromium oxide layer. This layer is very corrosion resistant which prevents rust formation and protects the underlying metal. Is...
Pennies aremade of zinc coated with copper. Only nickels are one solid material—that same 75% copper/25% nickel alloy. How can you tell real copper from fake? Real copper should havea reddish-brown hue, like a penny. Brass items tend to have a yellowish tint. If your item is yellow...
it is clear that replacements are not only needed, but will also ideally be required to meet acceptable anti-corrosion performance (which is now industrially expected and will also be demanded by consumers who have become accustomed to specific durability or warranties), and cost expectations as pr...
In the painted sample the following elements were found: iron, copper, nickel, zinc, magnesium, sulfur, titanium, barium, strontium, lead, silicon and chlorine. The elements with the highest ratio of appearance were titanium and barium.
