Consider the folowing mechanism for the oxidation of bromide ions by hydrogen peroxide in aqueous acid solution.
A certain weak base has a Kb of 8.70 × 10-7. What concentration of this base will produce a pH of 10.10
Why would pharmaceutical companies choose to use ethanol (CH3CH2OH) as a solvent in their cough medicine solutions, especially considering the fact that many people would prefer to avoid alcohol when they are sick or when administering this medici..
Find the pH during the titration of 20.00mL of 0.1000M triethylmine, Kb=5.2x10^-4, with 0.1000M HCl solution after the addition of 10.00mL of titrant
A concentrated sulfuric acid solution is 65.0% H2SO4 by mass and has a density of 1.55 g/mL at 20°C. What is the mass of 8.00 L of the concentrated sulfuric acid solution?
Question- Hydrazine (N2H4) and dinitrogen tetroxide (N2O4) form a self-igniting mixture that has been used as a rocket propellant. The reaction products are N2 and H2O. Write a balanced chemical equation for this reaction.
A 34.62 mL of 0.1510 M NaOH was needed to neutralize 50.0 mL of an H2SO4 solution. What is the concentration of the original sulfuric acid solution?
Rearrange the equation discovered by Balmer to solve for n2 (get n2 by itself): 1/? = R(1/2^2 - 1/n^2) where: ? = is the wavelength of the photon (E=hc/?) R = Rydberg's constant (1.0974x10^7 m^-1) n1 and n2 are integers where n2 > n1.
Suggest simple laboratory tests you could use to distinguish acetone, carbon tetrachloride, cyclohexane, ethyl ether and ethanol.
