A solution of potassium permanganate is treated with an excess of strong acid. What is the formula and systemic name of the strong acid product?
You are investigating the metabolism of glutamic acid in E coli, which enters the TCA cycle as a-Ketoglutarate following an initial transamination reaction.
A voltaic cell consist of gold in a gold(III)nitrate solution and copper in a copper(II)nitrate electrode. Calculate cell potential if the [Au3+] is 0.00750M and [Cu2+]=1.50M at 25 degrees celsius.
Triethylamine, (ch3ch2)3n, is a liquid that boils at 89C and has a viscosity of about 4 x10^-4 kg/ms. Explain the differences in properties of these two componds.
how many grams of sulfur are needed to react completely with 246 g of mercury to form HgS
A 13.00 g sample of an ionic compound NaA, where A- is the anion of a weak acid, was dissolved in enough water to make 100.0 mL of solution and was then titrated with 0.100 M HCl. After 550.0 mL of HCl was added, the pH was 5.00.
Oxygen gas, generated by the reaction 2KClO3(s) ? 2KCl(s) + 3O2(g), is collected over water at 27°C in a 3.78-L vessel at a total pressure of 730. torr. (The vapor pressure of H2O at 27°C is 26.0 torr.) How many moles of KClO3 were consumed in the..
Calculate the pH during the titration of 34.5 mL of 0.507 M triethylamine, (C2H5)3N with 0.148 M HCl after 13.0 mL of the acid have been added. Kb of triethylamine = 5.2 x 10-4.
A 16 ounce specialty coffee drink contains 200 mg caffeine. If all the caffeine is extracted and dissolved in an equal amount of water, what is the pH of the solution? What is the percent ionization
Calculate ΔG° at 25°C for the redox rxn between Sn4+ and Fe that takes place in a voltaic cell if E°cell= 0.60V. The rxn is: Sn4+(aq) + Fe(s)→ Fe2+(aq) + Sn2+(aq)
