(a)
Interpretation:
The balanced chemical equations for the given three steps processes involved in the production of high purity silicon needs to be determined.
Concept introduction:
The consecutive reactions take place one after another in a sequence to produce the final product. The simultaneous reactions involve the independent reaction of two or more substances reacting separately in another reaction at the same time.
The number of moles of a substance is related to mass and molar mass as follows:
Here, m is mass and M is molar mass.
(b)
Interpretation:
The masses of carbon, chlorine and hydrogen required for production of per kilogram of high-purity silicon needs to be determined.

In the first step, aluminum hydroxide reacts to form alumina Al2O3 and water: 2AlOH3s + Al2O3s -> 3H2Og In the second step, alumina Al2O3 and carbon react to form aluminum and carbon dioxide: 2Al2O3s + 3Cs + 4Als -> 3CO2g Suppose the yield of the first step is 83.% and the yield of the second step is 78.% . Calculate the mass of aluminum hydroxide required to make 7.0kg of aluminum. Be sure your answer has a unit symbol, if needed, and is rounded to the correct number of significant digits.arrow_forward

Chalcopyrite (CuFeS2) is one copper mineral that can be converted to elemental copper in a series of chemical steps. Reacting chalcopyrite with oxygen at high temperature produces a mixture of copper sulfide and iron oxide. The iron oxide is separated from CuS by reaction with sand (SiO2). CuS is converted to Cu2S in the process and the Cu2S is burned in air to produce Cu and SO2:2CuFeS2+3O22CuS+2FeO+2SO2 2FeO+2SiO22FeSiO32CuSCu2S+SCu2S+S+2O22Cu+2SO2 An average copper penny minted in the 1960s contained about 3.000 g of copper.
