8.1 2 EMISSION FACTORS 7 93 US EPA

carbon is accomplished by passing superheated steam through the carbon bed. A zinc oxide bed offers several advantages over the activated carbon bed. Steam regeneration to use as energy is not required when using a zinc oxide bed. No air emissions are created by the zinc oxide bed, and 7/93 (Reformatted 1/95) Inorganic Chemical Industry 8.1-1

Example Exercise 8.1 Evidence for a Reaction

Example Exercise 8.1 Evidence for a Reaction

A metal and oxygen react to produce a metal oxide. (a) Zinc is a metal with a predictable charge, that is, Zn. 2+. The formula of zinc oxide is ZnO. The balanced equation for the reaction is (b) Chromium is a metal with a variable charge. From the name chromium(III) oxide, we know the ion is Cr. 3+. The formula of the oxide is, therefore, Cr. 2 ...

There are also several pyrometallurgical processes that reduce zinc oxide using carbon, then distil the metallic zinc from the resulting mix in an atmosphere of carbon monoxide. The major downfall of any of the pyrometallurgical process is that it is only 98% pure; a standard composition is 1.3% lead, 0.2% cadmium, 0.03% iron, and 98.5% zinc.

zinc processing Britannica

zinc processing Britannica

History. The separation of metallic zinc from its ores by pyrometallurgy is much more difficult than with other common metals, such as copper, lead, and iron, because the reduction of zinc oxide by carbon (C) proceeds spontaneously only above the zinc boiling point of 907 C (1,665 F). Efficient methods of condensing the vapour to liquid metal were not discovered until the 14th century.

Single Displacement Reaction Zinc and Copper II Ion

When zinc metal is immersed in a solution of 0.1 M aqueous copper(II) sulfate solution c opper metal plates out on the zinc.The solution is initially blue in color. A dark coating of copper metal appears on the zinc within two minutes and when 45 minutes have elapsed, there is a thick coat of copper metal powder on the zinc strip and the blue color of the solution has lightened considerably.
