Your boss has asked you to prepare a solution of an acetate buffer. Unfortunately, you only have a bottle of 0.235M of acetic acid, CH, OH, and a bottle of 0.200M of NaOH. Note that the pK of CH 2 CO H is 4.74. a) How many moles a of CHOH are in 100.0mL of a 0.235M solution of acetic acid? b) How many moles of NaOH must you add to the 30 100.0mL0.235M acetic acid to obtain a buffer solution with a pH of 4.70 ? c) What volume of 0.200MNaOH must you add, in mL, to reach that pH?

Q2 (a) Given that the enthalpy values for the following reactions are: AH = -1049.0 kJ 2 Al (5) + 6HCI (ад) — 2 ALCI3 (аg) + 3 Н2 (9) AH = -74.8 kJ HCl (g) → HCl (aq) + Cl2 (g) → 2HCI AH = -185.0 kJ H2 (9) + AlCl3 (s) → AlCl3 (aq) (g) AH = -323.0 kJ ΔΗ Manipulate the reactions above to determine AH for: 2 Al(s) + 3 Cl2 (9) → 2 AlCl3 (s) In one experiment, a 25 g sample of an alloy was heated to a certain temperature. (b) The heated alloy was then dropped into a beaker containing 90 g of water at 25.32 °C. The temperature of the water rose to a final value of 27.18 °C. Predict the final temperature that the alloy is being heated at the beginning of the experiment. Given that the heat capacity of water and alloy are 4.184 Jgl°C-' and 0.3847 Jg l°C' respectively.

[Review Topics] [References] Use the References to access important values if needed for this question. Ethanol, C2H,O, is most often blended with gasoline - usually as a 10 percent mix - to create a fuel called gasohol. Ethanol is a renewable resource and ethanol-blended fuels, like gasohol, appear to burn more efficiently in combustion engines. The heat of combustion of ethanol is 326.7 kcal/mol. The heat of combustion of hexane, C,H14, is 995.0 kcal/mol. How much energy is released during the complete combustion of 479 grams of hexane ? kcal Assuming the same efficiency, would 479 grams of ethanol provide more, less, or the same amount of energy as 479 grams of hexane?

Order these chemical species by increasing pH of an 0.1 M aqueous solution of each. That is, imagine making an 0.1 M solution of each species. Select1 next to the species that makes the solution with the lowest pH. Select 2 next to the species that makes the solution with the next higher pH, and so on. Notice that some of the rankings have been filled in for you already. Also notice that water is on the list. For that particular case, just compare the pH of pure water to the pH of the other solutions. Note for advanced students: for all charged species, you may assume the necessary counterions act as neither acids nor bases. relative pH of 0.1 M aqueous solution species H20 4 H,PO4 HNO, (Choose one) NO2 7 OH (Choose one) HF (Choose one) ▼
