The concentration of glucose inside a cell is 0.14mM. outside the cell the concentration of glucose is 12.8 mM. Calculate the change in Gibbs free energy for the transport of 5.00 moles of glucose into the cell at 37 celsius.
Acid-base titration & analytical chemistry, A 0.213-g sample of uranyl(VI)nitrate, UO2(NO3)2, is dissolved in 20.0 mL of 1.0 M H2SO4 and shaken with Zn. The zinc reduces the uranyl ion, UO2 (with a charge of 2+)
