During a refueling outage, workers discover black, soft material in the reactor core (obviously a Foreign Materials Exclusion Area breech). To help identify the breech source, you are asked to determine the material
What wieght of glycine (pka1=2.4, pka2=9.6) and what volume of 0.5 N(normality) HCl would be necessary to make 100 mL of 0.2 M buffer pH 2.4?
Calculate the following values at 25C using standard potentials as needed. E°cell, E cell, deltaG°rxn, and deltaGrxn
When cyclopentane is exposed to Br2 in the presence of light, reaction occurs. Write the formulas of all possible monobromination products. Draw molecule by placing atoms on grid.
Hard water contains Ca2+, Mg 2+, and Fe2+. Water softeners replace these ions with Na+. If 1.0 X 10^3L of hard water contains 0.010 M Ca2+ and 0.0050 M Mg2+
Assume you dissolve 0.235 g of the weak acid benzoic acid, C6H5CO2H, in enough water to make 9.00 multiplied by 102 mL of solution and then titrate the solution with 0.148 M NaOH. C6H5CO2H(aq) + OH-(aq) = C6H5CO2-(aq) + H2O(l)
What structure best represents the rate-determining intermediate formed when 1-methylcyclopentene reacts with Cl2.
Why does aluminum hydroxide readily dissolve in concentrated NaOH but not in concentrated NH3. Please give a thorough explanation, not just a short answer.
