What is the Ka of the amino acid glutamine if it is 33.0% dissociated at pH = 8.82?
Gibbs Free Energy and Equilibrium The reaction SO2(g)+2H2S(g)?3S(s)+2H2O(g) is the basis of a suggested method for removal of SO2 from power-plant stack gases
A radio station's channel, such as 100.7 FM or 92.3 FM, is actually its frequency in megahertz ({\rm MHz}), where 1\; {\rm MHz}=10^6\; {\rm Hz}. Calculate the broadcast wavelength of the radio station 102.7 FM
h3po4 undergoes three ionization equilibria for each ionization pkasnbsp 2.12 7.21 and 12.3nbsp respectively. a
Calculate the solubility (in M units) of ammonia gas in water at 298K and a partial pressure of 6.50bar . The Henry's law constant for ammonia gas at 298K is 58.0 M/atm
Really struggling with this one dy/dt = 2t(y + 1) + 2at^3 where a is a parameter. Find the general solution of the ODE when a = 0 using the fact that it is separable. After this, use the fact that that it is a linear ODE to find an integrating fac..
Calculate the concentration (in molarity) of a Ba(OH)2 solution if 25.0 mL of the solution are needed to neutralize 20.0 mL of a 0.500 M HCl solution
Write the reaction for the electrolysis of molten RbCl. Do not include physical states in the reaction. Include balancing coefficients (use only whole numbers).
What is the pH at the equivalence point? what is the pH at the 10.0 mL base added? what is the pH at the 30.0 mL base added?
What volume of 6.00 M sodium hydroxide in milliliters must be diluted to 220.0 mL to make a 1.50 M solution of sodium hydroxide
This was allowed to react under reflux for an hour and then the products seperated. I wrote out a mechanism before lab and ended up predicting 4-chlorobenzoic acid and 4-chlorophenol as my final products.
an electrochemical cell consists of a nickel metal electrode immersed in a solution with ni2 1.0 m separated by a
If you used 20 ml water to recrystallize salicylic acid at 10 °C, estimate the amount of product that can be lost as a result of dissolving in the filtrate. (solubility at 10 °C =0.14/100 ml water). Calculate the loss if you had used 4 mls of wate..
