14) If the density of propanol is 0.828 g/mL and a sample of propanol has a mass of 14.5 g, what is the volume of that sample in liter? (Volume=mass/density) 17.51 |

Consider the two solutions separated by an ideal semipermeable membrane (permeable to water but impermeable to solute).  Assuming complete dissociation of all the salts you can expect: a.) net water movement from side 1 to side 2 b.) net water movement from side 2 to side 1 c.) no net water movement

4.1 11 (a) Define a buffer solution (b) What are the components of (i) an acidic buffer ? (ii) a basic buffer?

Mary is severely dehydrated from multiple and prolonged bouts of diarrhea. Her labs are returned. pH - 7.3 (normal 7.4) PACO2 = 33mmHg (normal 40mmHg) [Na} - 140mEq/L -normal HCO3- = 16mEq/L (normal) metabolic acidosis O metabolic akalosis respiratory acidosis O respiratory alkalosis

One type of diuretic given to people with high blood pressure, renal disease and congestive heart failure are thiazide-type diuretics. These drugs inhibit sodium ion reabsorption by inhibiting the transport in the ascending limb of the loop of Henle. A) What does it mean to inhibit the transport of sodium ions in the loop of Henle? B) Explain how this inhibition of sodium ions in the loop of Henle could help increase urine production.

The phosphate buffer system is most important in the Choose from the following: (A) respiratory system (B) cardiovascular system (C) digestive system (D) urinary system

Buffer systems can absorb hydrogen ions from the blood to increase pH into homeostatic range (pH: 7.35 to 7.45)During what condition would buffer systems do this?
