- Three reactions very important to the semiconductor industry are The reduction of silicon dioxide to crude silicon, SiO2(s) + 2 C(s) → Si(s) + 2 CO(g) ΔrH° = 689.9 kJ/mol The formation of silicon tetrachloride from crude silicon, Si(s) + 2 Cl2(g) → SiCl4(g) ΔrH° = −657.01 kJ/mol The reduction of silicon tetrachloride to pure silicon with magnesium, SiCl4(g) + 2 Mg(s) → 2 MgCl2(s) + Si(s) ΔrH° = −625.6 kJ/mol Calculate the overall enthalpy change when 1.00 mol sand, SiO2, changes into very pure silicon by this series of reactions.arrow_forwardOne of the few industrial-scale processes that produce organic compounds electrochemically is used by the Monsanto Company to produce1,4-dicyanobutane. The reduction reaction is 2CH2CHCH+2H++2eNC(CH2)4CN The NC(CH2)4CN is then chemically reduced using hydrogen gas to H2N(CH2)6NH2, which is used in the production of nylon. What current must be used to produce 150.kg NC(CH2)4CN per hour?arrow_forwardThe space shuttle Orbiter utilizes the oxidation of methylhydrazine by dinitrogen tetroxide for propulsion: 4N2H3CH3(l)+5N2O4(l)12H2O(g)+9N2(g)+4CO2(g) Calculate H for this reactionarrow_forward

First the selenium isoxidized to selenous acid by nitric acid. Then the selenous acid is oxidized by potassium permanganate toselenic acid. The equations are:3 Se (s) + 4 HNO3 (l) + H2O (l) → 3 H2SeO3 (aq) + 4 NO (g)8 H2SeO3 (aq) + 2 KMnO4 (aq) → 5 H2SeO4 (aq)+ K2SeO3 (aq)+ 2 MnSeO3 (aq) + 3 H2O (l)What mass of selenic acid (in kg) can be produced from 1.00 kg of Se?Molar masses (g/mol): Se 78.96 H2SeO4 144.97arrow_forward

- The Solvay process for the manufacture of sodium carbonate begins by passing ammonia and carbon dioxide through a solution of sodium chloride to make sodium bicarbonate and ammonium chloride. The equation for this reaction is H2O + NaCl + NH3 + CO2 → NH4Cl + NaHCO3 In the next step, sodium bicarbonate is heated to give sodium carbonate and two gases, carbon dioxide and steam. 2NaHCO3 → Na2CO3 + CO2 + H2O What is the theoretical yield of sodium carbonate, expressed in grams, if 128 g of NaCl were used in the first reaction? If 84.4 g of Na2CO3 was obtained, what was the percentage yield?arrow_forwardSuppose a pair of chemical compounds A and B can react in two different ways: A+B → C Reaction 1 gives product C. A+B → D Reaction 2 gives product D. The following facts are known about the two reactions: ● Reaction 1 is endothermic and Reaction 2 is exothermic. • If a reaction vessel is charged ("filled") with A and B, then at first C is produced faster than D. Use these facts to sketch a qualitative reaction energy diagram for both reactions. Note: because these sketches are only qualitative, the energies don't have to be exact. They only have to have the right relationship to each other. For exam if one energy is less than another, that fact should be clear in your sketch.
