(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.

Solution Summary: The author explains the balanced chemical equations for the given three steps processes involved in the production of high-purity silicon.
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.
Interpretation Introduction
(b)
Interpretation:
The masses of carbon, chlorine and hydrogen required for production of per kilogram 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:
23. Which of the following statements is false about baking soda?
a. Baking soda chemically yields carbon dioxide in the presence of moisture and alkali.
b. Up to ¼ teaspoon of baking soda is required for each cup of flour to be leavened.
Baking soda is only used when the flour mixture includes acidic ingredients.
d. Acid reacts with baking soda and creates carbonic acid that then reacts to give off carbon
dioxide and water.

A. 2NAHSO3 + H2SO4 → Na2SO4 + 2SO2 + 2H2O
O B. H2S(aq) + H20 → HS-(aq) + H3O*(aq)
O C. H2S2 → H2S + S
D. Cu + 2H2SO4 CuSO4 + SO2 + 2H2O
E. SO3 + SCI2 - SOCI2 + SO2
