In each of two flasks, a solution is prepared by placing 0.25 moles acetic acid (CH3COOH) and 0.25 moles acetate ions (CH3COO-) in sufficient water to prepare 1.00L of solution.
A.) Added to the solution in one flask, 0.15 moles KHSO4 (s). Describe the effect of this on [CH3COOH] and [CH3COO-] (their concentrations). Account for your answer in terms of number of moles of protons transferred. Also, has the capacity of the buffer been exceeded? Explain.
B.) Added to the solution in the other flask is 0.40 moles NaOH (s). Describe the effect of this on [CH3COOH] and [CH3COO-]. Account for your answer in terms of number of moles of protons transferred. Also, has the capacity of the buffer been exceeded? Explain.
Calculate the Ki for a competitive inhibitor (I) form the following data. (Slope of reciprocal plot value: 0.1, 0.35, 0.5, 1.0, 1.5, 2.0)
A mixture of Ne and Ar gases at 347 K contains twice as many moles of Ne as of Ar and has a total mass of 52.0 g. If the density of the mixture is 3.86 g/L, what is the partial pressure (in atm) of Ne?
The partial pressures of gas A and gas B, respectively, are 0.263 atm and 0.676 atm. If 0.160 mol a third gas is added with no change in volume or temperature, what will the total pressure become?
After adding 0.25 mL of 0.50 M NaOH, the pH of the same solution changed to 8.05. Calculate the buffer capacity (? mmol OH-/? pH) of this solution to two decimal places.
Nitrosyl bromide, NOBr, is 34 percent dissociated at 25 deg. C and the total pressure is 0.25 atm.
Three gases (8.00g of methane, , 18.0g of ethane, , and an unknown amount of propane, ) were added to the same 10.0L- container. At 23.0 degrees Celcius , the total pressure in the container is 5.40atm . Calculate the partial pressure of each gas ..
Decide whether or not each of the following metals dissolves in 1 {rm M} {rm HCl}. For these metals that do dissolve, write a balanced redox reaction showing what happens when the metal dissolves.
Enough of a monoprotic acid is dissolved in water to produce a 0.0155 M solution. The pH of the resulting solution is 2.43
write the amino acid sequence in the N-terminal to C-terminal direction. Use the three-letter amino acid abbreviations (for example, Glu-Asp-Val).
Magnesium oxide (MgO) has the rock salt crystal structure and a density of 3.58 g/cm3. Determine the unit cell edge length.
if 6.73 g of NaCo3 is dissolved in enough water to make 250. mL of solution what is the molarity of the sodium carbonate ?
A tank initially at a pressure of 6.70 atm contains 2.0 moles of oxygen gas at 25.0 degrees celsius. Its temperature is then increased to 45.0 degrees celsius
