Question 1: What are three differences between organic and inorganic and explain
Question 2: Why ions must be transported into and out of a cell whereas steroids can pass through via simple diffusion.
A. Each group will require ~7 solutions where a single BCG Bromocresol Green concentration exists (~2 x 10-5 M) with different concentrations of NaCl (0.02M-0.2M). Compute the preparation scheme to prepare these solutions utilizing the following c..
Then 1.00 mL of a 10.9 mM Lithium standard was added to 9.00 mL of serum, and this spiked serum gave an intensity reading of 721 units. What is the original concentration of Li in the serum?
A gas sample containing 1.65 mol at 25°C exerts a pressure of 413 torr. Some gas is added to the same container, and the temperature is increased to 50.°C.
The equation for the combustion of gaseous methanol is: 2CH3OH(g) + 3O2(g) ? 2CO2(g) + 4H2O(g) Estimate the ?H°rxn per mole of methanol combusted, using the bond energy data provided below
Calculate the pH at the halfway point and at the equivalence point for each of the following titrations. (a) 100.0 mL of 0.42 M HC7H5O2 (Ka= 6.4 multiplied by 10-5) titrated by 0.42 M NaOH halfway point equivalence point
Given the initial rate data for the reaction A+B->C, determine the rate expression for the reaction. [A], M [B], M delta[C]/delta t (initial) M/s
what is the [H3O+] and the pH of a benzoic acid-benzoic buffer that consists of 0.15 M C6H5COOH and .47 M C6H5COONa? (Ka of benzoic acid = 6.3 * 10^-5)
In countries where potassium iodide is added to salt, iodine deficiency or goiter has been almost completely eliminated. The recommended daily allowance (RDA) for iodine is 150 pg/day.
Analysis shows that there are 1.8 moles of H2, 7.45e-05 moles of S2, and 7.2 moles of H2S present in a 50.8 L flask at equilibrium. Calculate the equilibrium constant Kc for the reaction.
Given that the present flux of anthropogenic Na+ into the oceans is 3.39 x 1012 mol yr-1, how long would it take to increase the concentration of Na+
Assuming there is linearity between the chromatographic signal and the lithium concentration, what will be the concentration of lithium in the patient's
