glucose is transported into the intestinal cells via cotransport with sodium. Assume the following conditions:
Temp = 37o CSodium (in) = 12.0 mMSodium (out) = 145 mMGlucose (out) =28 μMΔΨ = -72mV (inside is negative)
a. What is the ΔG for sodium transport?b. What is the upper limit of glucose transport?
If pH = 6.4, calculate the molar concentration of H^+ (aq) in the solution. If pH = 6.4, calculate the molar concentration of OH^-(aq) in the solution.
A buffer solution of a weak base as well as its salt had a pH of 9.45 when the base was 0.110 M and the cation was 2.00 M. Compute the equilibrium dissociation constant (Kb).
A steel cylinder with a volume of 19.5 L contains N2 gas at a pressure of 91.0 atm and a temperature at 0 C. Determine the mass of N2 in the cylinder
Low-melting solids often "oil out" of a recrystallization solution rather than crystallizing. If this were to happen, how would you change the recrystallization procedure to ensure good crystals
Using the same assumptions and approximations you used in lab, determine the molar enthalpy change (in kJ/mol) for the reaction below, assuming that CH3CO2H dissociates completely in water.
if the freezing point of a 0.106m CH3COOH solution is -0.323 degrees celcius, what is the percent of acid that has undergone ionization?
Find the formal concentration of the acid in each phase when 100 mL of 0.10 M aqueous acid is extracted with 35 mL of octanol at (a) pH 4.00 and (b) pH 9.00.
magnesium oxide decomposes to form 7.29 of magnesium, what mass of oxygen gas is also released in the reaction?
How many grams of Cu(OH)2 will precipitate when excess KOH solution is added to 63.0 mL of 0.610 M CuSO4 solution.
If 66.5 ml of base is required to reach the second equivalence point, what is the concentration of the acid?
A one-gram sample of wood taken from a living tree gives a rate forcarbon-14 decay of 13.6 counts per. If the half-life for carbon-14is 5720 years, Explain how old is a wood sample that gives a rate for carbon-14 decay of 3.9 counts per minute?
The mixture was stirred, causing all of the sample to dissolve. The excess HCl in the solution required 38.4 mL of 0.164 M NaOH for complete neutralization in a titration. What was the molecular formula of the white substance
