Tris is widely used in a biochemical laboratory. Its acid dissociation constant is 8.32 x 10^-9. You have available at your lab bench a 0.1 M solution of Tris in its protonated form, 0.1 M solution of HCL and NaOH,
A sugar-water mixture contains 45.8 g of sugar and 108.5 g of water. What is the percent by mass of sugar and the percent by mass of water in the solution?
Gaseous hydrogen iodide is placed in a closed container at 425 degree celcius, where it partially decomposes to hydrogen and idine: 2HI(g)--->--->H2(g)+I2(g). At equilibrium it is found that (HI)=3.53*10^-3 M,(H2)=4.79*10^-4M, and (I2)=4.79*10^-4M..
What is the purpose of the gas trap in the reaction set-up? (Hint: What gas(es) are present?What are their safety issues?)
Consider one mole of a monatomic ideal gas at 300 K that udergoes a free expansion from a volume of 1m^3 to 10 m^3. a). How much does the chemical potential of each molecule in the gas change?
calculate the pH of the resultant solution: (a) 0.00 mL, (b) 5.00 mL, (c) 25.00 mL, (d) 45.00 mL, (e) 50.00 mL, (f) 51.00 mL.
A sample weighing 25g starts at 99 degrees celsius. It is put in a calorimeter containing 100g water. The water temperature begins at 20 degrees and both water and sample reach equilibrium at 32 degrees. What is the specific heat of the sample?
What is the equilibrium constant Kc of this reaction? Use an ICE table with numbers.
A 1.784 gram sample containing an unknown amount of arsenic trichloride and the rest inerts was dissolved into a NaHCO3 and HCl aqueous solution.
Erythrocytes phosphorylate glucose to glucose 6-phosphate with the help of the enzyme hexokinase instead of glucokinase. Hexokinase has a Km = 0.04 mM.
Solids generally expand as the temperature increases. Such an expansion results from an increase in the bond length between adjacent atoms as the vibrational amplitude increases.
A gas is heated from 268 K to 290 K while its volume is increased from 25.0 L to 37.0 L by moving a large piston within a cylinder. If the original pressure was 0.90 atm, what would be the final pressure?
