What are the main 2 subtypes of calcium channel blockers for the dihydropyridines and the nondihydropyridines? How are they different in clinical effects and indications?
What is the pH of a solution that results from addition of 100 ml of 1 M HCl (a strong acid) with 100 ml of 1 M NaOH (a strong base)?
A solution is made by dissolving 25g of NaCl in enough water to make 1.00 L of solution. Assume that the density of the solution is 1.00 g/cm3. Calculate the mass percent, molarity, molality, and mole fraction of NaCl
Using a sample that was dissolved in CH 2 Cl 2 , mixed alumina, evaporated the CH 2 C l2 , loaded and began to run his column, starting with C 6 H 14
What volume of concentrated HCl (12 M) and what weight of solid tris-(hydroxymethyl)aminomethane (as the base) are required to make 100 mL of 0.250 M buffer, pH 8.0 (pK of Tris hydrochloride if 8.0)?
Show that the Slater determinant formalism automatically incorporates the Pauli exclusion principle by evaluating the He ground-state wave function of Equation 10.8, giving both electrons the same quantum numbers.
Which laboratory techniques are required to separate the components of a solid mixture and obtain each component in solid form. Also describe the goal of each technique.
if your pipet was calibrated incorrectly so it transferred too muchsolution the density you calculated for the liquid
Explain how many grams of C2H2 must burn according to the equation below in order to heat 2.34x104 grams of H2O from 25*C to 50*C. C2H2(g) + 5/2 O2(g) > H2O(l) + 2CO2(g) (Delta H = -1212kJ)
The decomposition of carbon disulfide, CS2 to form carbon monosulfide, CS and sulfur is first order with k = 2.8 x 10^-7 / second at 1000 degrees C. CS2 => CS + S determine how many days would be needed before a 1.00 gram sample of CS2 had decompo..
