Question- The standard free energy change for the hydrolysis of ATP is -30.5 kJ. In a particular cell, the concentrations of ATP, ADP, and Pi are 3.6×10 3M, 1.4×10 3M, and 5.5×10 3M, respectively.
Calculate the free energy change for the hydrolysis of ATP under these conditions. Assume a temperature of 298 K.
Identify compound Z in the following sequence. (CH3)2CHCH2CN ---HCl, H2O, heat---> compound X ---1. LiAlH4, diethylether, 2. H20 ---> compound Y --- PCC, CH2Cl2 ------> compound Z 1. (CH3)2CHCH2COH (the O is double bonded to the C)
the wavelength of the emitted photon corresponds to the difference in energy between the two energy levels. What were the principal quantum numbers of the initial and intermediate excited states involved?
A solution is prepared by adding 0.500 g of solid NaCl to 50.0 mL of 0.100 M {CaCl_2}. What is the molarity of chloride ion in the final solution? Assume that the volume of the final solution is 50.0 mL.
Even if a cospotted TLC analysis of an unknown with an authentic standard is performed, one still does not know with complete certainty that the unknown and the standard are identical.
