Many computer chips are manufactured from silicon, which occurs in nature as SiO2SiO2. When SiO2SiO2 is heated to melting, it reacts with solid carbon to form liquid silicon and carbon monoxide gas. In an industrial preparation of silicon, 156.7 kgkg of SiO2SiO2 is allowed to react with 79.3 kgkg of carbon to produce 66.2 kgkg of silicon. Determine the theoretical yield for the reaction. Express your answer using four significant figures.   Determine the percent yield for the reaction.

Blast furnaces extra pure iron from the iron(III) oxide in iron ore in a two step sequence. In the first step, carbon and oxygen react to form carbon monoxide: 2Cs + O2g -> 2COg In the second step, iron(III) oxide and carbon monoxide react to form iron and carbon dioxide: Fe2O3s + 3COg + 2Fes -> 3CO2g Suppose the yield of the first step is 89.%  and the yield of the second step is  74.% . Calculate the mass of carbon required to make  7.0kg  of iron.   Be sure your answer has a unit symbol, if needed, and is rounded to the correct number of significant digits.

Manganese commonly occurs in nature as a mineral. The extraction of manganese from the carbonite mineral rhodochrosite, involves a two-step process. In the first step, manganese (II) carbonate and oxygen react to form manganese (IV) oxide and carbon dioxide: 2 MnCO3(s) + O₂(g) 2 MnO₂ (s) +2 CO₂(g) In the second step, manganese (IV) oxide and aluminum react to form manganese and aluminum oxide: 3 MnO₂ (s) +4 Al(s)-3 Mn(s)+2 Al₂O3(s) Write the net chemical equation for the production of manganese from manganese (II) carbonate, oxygen and aluminum. Be sure your equation is balanced. 0 Continue * FOR 80 FS F4 F5 0-0 X MacBook Air F6 4 Ś F7 A DI FB © 2023 McGraw Hill LLC. All Rights Reserved. Terms of Use | Privacy Center F9 A Submit A F10

Silicon carbide or carborundum is a widely used ceramic material in car brakes and bullet-proof vests because of its hardness. Carborundum is found naturally in the mineral moissanite, but the demand for it exceeds the supply. For this reason it is generally synthesized in the laboratory. The reaction is: SiO2 + 3 C→SiC + 2 CO How many kg of silicon carbide can be formed by the reaction of 250.0 kg of sand (SiO2) with excess carbon?

Aspirin can be made in the laboratory by reacting acetic anhydride (C4H6O3C4H6O3) with salicylic acid (C7H6O3C7H6O3) to form aspirin (C9H8O4C9H8O4) and acetic acid (C2H4O2C2H4O2). The balanced equation isC4H6O3+C7H6O3→C9H8O4+C2H4O2C4H6O3+C7H6O3→C9H8O4+C2H4O2In a laboratory synthesis, a student begins with 3.10 mLmL of acetic anhydride (density=1.08gml−1density=1.08gml−1) and 1.23 gg of salicylic acid. Once the reaction is complete, the student collects 1.22 gg of aspirin.    Determine the percent yield of aspirin for the reaction. Express your answer using three significant figures.
