How do you find the value of Ka for NaHSO4 if you are given the concentration of H+ and the initial molar concentration of NaHSO4?
A buffer is made up of 355 mL each of 0.200 M NaHCO3 and 0.134 M Na2CO3. Assume that volumes are additive. Enough water is added to this buffer to make the total volume 10 L. Calculate the pH of the buffer after the addition of 0.0300 mol of HCl t..
Predict and sketch the likely splitting patterns and relative integrations for them most downfield resonance(s) in the proton NMR spectra of both primary alcohols below. Explain why the two patterns are different.
If the salt bridge consists of a gel containing approximately 1 M KNO3, will the NO3-ions flow into the right hand (Cu, Cu2+) or left hand (Al, Al3+) half-cell when the circuit is completed
a student combusts 504.96 grams of ethene gas c2h4. how many liters of co2 g are produced at a pressure of 0.993 atm
Calculate the pH of a solution made by adding 40. g of sodium acetate, NaCH3COO, to 21 g of acetic acid, CH3COOH, and dissolving in water to make 700. mL of solution
A general chemistry student found a chunk of metal in the basement of a friend's house. To figure out what it was, he used the ideas just developed in class about density.
When 2-propanol was used as the developing solvent, two substances moved with the solvent front (Rf = 1) during TLC analysis on a silica gel plate. Can you conclude that they are identical? If not, what additional experiment would you perform?
The bond dissociation energy of H2 and Cl2 are 436 and 242 kJ/mol, respectively. The Pauling electronegativity of H and Cl are 2.3 and 3.2. What is the HCl bond dissociation energy
A solution is made by dissolving 3.14g of NaCl in 79.9mL of water. What is the concentration of sodium chloride in units of weight/volume percent?
An imine is a special type of amine that has a carbon-nitrogen double bond. Construct an orbital interaction diagram that compares a carbon-nitrogen double bond to a carbon-oxygen double bond on the same energy scale.
With pertinent thermo data, show why N2O4 (g) cannot be made by direct combination of constituent elements at standard state conditions. LS analysis is also useful.
Explain what volume (in milliliters) of 0.100 M NaOH must be added to a 0.120 L solution of 0.015 M glycine hydrochloride pKa1 = 2.350, pKa2 = 9.778 to adjust the pH to 2.37?
