An aqueous solution of KI has a freezing point of -1.95 C and an osmotic pressure of 27.0 atm at 25.0 C.
Assuming that the KI completely dissociates in water, what is the density of the solution? (in g/cm3)
If all the pyruvate is metabolized by the glyoxylate bypass (assume that 50% of the pyruvate enters in the citrate synthase reaction and 50% during the bypass), what would be the labeling pattern and its distribution in the oxaloacetate?
determine the ph of the following solutions, showing calculations.
Consider the hypothetical reaction, A + B ® C, with the rate law, Rate = k[A]2[B]. If the concentration of A is 0.650 mol/L, the concentration of B is 0.100 mol/L, and the rate is 1.70 M/min, calculate the rate constant,
