What are the equilibrium concentrations of all species of 18.0M acetic acid at 25°C? What is the pH and %ionization?

The extraction of aluminum metal from the aluminum hydroxide found in bauxite by the Hall-Héroult process is one of the most remarkable success stories of 19th century chemistry, turning aluminum from a rare and precious metal into the cheap commodity it is today. 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.

In the "Methodé Champenoise," grape juice is fermented in a wine bottle to produce sparkling wine. The reaction is )) C6H1206(aq) → 2C2H50H(aq) + 2C02(g) Fermentation of 750. mL of grape juice (density = 1.0 g/cm3) is allowed to take place in a bottle with a total volume of 825. mL until 12.5% by volume is ethanol (C,H;OH). Assuming that the Co, is insoluble in H,0 (actually a wrong assumption), what would be the pressure of CO, inside the wine bottle at 25°C? (The density of ethanol is 0.79 g/cm3)

The mass of the original mixture was 2.03g. The combined mass of the salt and the evaporating dish was 48.92g with the tare mass of the evaporating dish being 47.98g. The combined mass of the sand and watch glass and filter paper was 32.15g with the tare mass of the watch glass being 30.91g and of the filter paper being 0.28g. 1A) calculate the mass of the table salt recovered. 2A) Calculate the mass of sand recovered 3A)calculate the total mass of table salt and sand recovered.  4A)Calculate the percent table salt in recovered material. 5A) calculate the table salt in the original mixture.

The reduction of iron(III) oxide to iron during steel-making can be summarized by this sequence of reactions: 20(s) +0, (g) =2 CO (g) K, Fe,0, (s) +3 CO (g) =2 Fe (1) +3 CO, (g) K2 The net reaction is: 2 Fe,O, (s) +6C (s) +30, (g)=4 Fe (1) +6CO, (3) K Write an equation that gives the overall equilibrium constant K in terms of the equilibrium constants K, and K,.

The great French chemist Antoine Lavoisier discovered the Law of Conservation of Mass in part by doing a famous experiment in 1775. In this experiment Lavoisier found that mercury(II) oxide, when heated, decomposed into liquid mercury and an invisible and previously unknown substance: oxygen gas. 1. Write a balanced chemical equation, including physical state symbols, for the decomposition of solid mercury(II) oxide (HgO) into liquid mercury and gaseous dioxygen. х10 2. Suppose 14.0 mL dioxygen gas are produced by reaction, at a temperature of 110.0 °C and pressure of exactly 1 atm. Calculate the mass of mercury(II) oxide that must have reacted. Be sure your answer has the correct number of significant digits.

Consider a small bird of mass 30 g. What is the minimum mass of glucose that it must consume (and burn) to fly up to a branch 10 m above the ground?

12. A buret is filled with deionized (DI) water and the stopcock is used to adjust the meniscus of the water in the buret to an initial value of 1.06 mL. The stopcock is opened and the DI water is dispensed in a flask. The stopcock is closed and the final buret reading is 15.72 mL. The volume of DI water (mL) in the flask is 14.66 35.34 16.8 14.7
