Using the method of successive approximations, what is [H3O+] in 0.500 M (Ka= 1.1*10^-2) and how many iterations (n) are needed to validate that a constant value had been obtained?Ka= [H3O+] [NO2-] / [HNO2]Using the method of successive approximations, what is \rm [H_3O^+] in 0.00500 M ~\rm CH_2ClCOOH(aq) (K_{\rm a}=\rm 1.4\times 10^{-3}) and how many iterations (n) are needed to validate that a constant value had been obtained?
A buffer is prepared by adding 1.50X 10^2 ml of 0.250 M NaOH to 2.50X10^2 ml of 0.350 M weak acid, HB. The solution is diluted to 1.00 L. If the pH of the resulting solution is 6.55, what is the pKa of the weak acid
A 45.5 g sample of copper at 99.8 degrees C is dropped into a beaker containing 152 g of water at 18.5 degrees C. What is the final temperature when thermal equilibrium is reached?
Write the balanced (i) molecular equation, and (ii) net ionic equation which show what happens when aqueous solutions of barium nitrate and potassium sulfate are mixed together. Identify the spectator ion(s) Is this correct
Calculate the molar solubility of AgI in 3.6 M NH3. The overall formation constant for Ag(NH3)2+ is 1.7 x 10^7.
Verify the first equality in R (beta(delta e)^2e^Beta(delta e)/[e^Beta(delta e)-1]^2 using the chain rule, and then verify the second equality in the same bolded equation by evaluating the derivative with respect to Beta
Explain qualitatively how the results of the experiment would differ when potassium tert-butoxide is used as the base instead of potassium hydroxide. A correct answer will identify how the result(s) would differ, and explain mechanistically why th..
Draw the fat molecule whose components are glycerol and butanoic acid. You may omit hydrogen atoms.
How many grams of Na2EDTA·2 H2O (FM 372.23) should be mixed with 2.07 g of Ca(NO3)2·2 H2O (FM 200.12) in a 500 mL volumetric flask to give a buffer with pCa2+ = 9.00 at pH 9.00?
What is the magnitude of the partial positive and partial negative charges in the HBr molecule? (1D = 3.36 × 10-30 C m; 1e- = 1.6022 × 10-19 C; bond length HBr = 1.41 angstroms; Dipole Moment HBr = 0.82D)
A titration experiment is set up to use 0.235M bleach (NaOCl) to analyze CrO2-. If 50.0mL of the CrO2-(aq) solution required 37.75mL of bleach to react to completion, what would you calculate as the molarity of the CrO2- solution
A reaction that is used to propel rockets is N2O4(l) + 2N2H4(l) --> 3N2(g) + 4H2O(g). This reaction has the advantage that neither product is toxic, so no dangerous pollution is released.
