a spherodial bacterium with diameter of 1 um contains twomolecules of a particular protein. what is the molar
The boiling point of a substance is defined as the temperature at which liquid and vapor coexist in equilibrium. Use the heat of vaporization (30.91kJ/mol) and the entropy of vaporization
Why do heavier atoms have a larger translational partition function than lighter atoms at the same temperature?
If 9.0 g of Al metal react with excess HCL according to the balanced equation (2Al(s) + 6HCL(aq)----> 2AlCl3(aq) + 3H2(g)), what volume of hydrogen gas at STP will be produced
Consider the cell described below: Al/Al3+ (1.00M)//Pb2+ (1.00M)/Pb Calculate the cell potential after the reaction has operated long enough for the [Al3+] to have changed by .60 mol/L. Assume T=25 C
why is it important to standardize NaOH solution instead of taking an accurate and diluting it in a volumetric
The approximate molarity of this solution will be 0.025 M. You will take 10.0 mL of a 0.0100 M KIO3 solution, dissolve excess amounts of KI in it, and using the Na2S2O3 solution, titrate to the disappearance of the starch I2 color. Using the appro..
