Question
Chapter 18, Problem 56P
Interpretation Introduction
Interpretation:
The correct option explaining how the calcium channel blockers work to lower the blood pressure should be chosen-
- Causing the kidneys to excrete more water and thus lower the blood volume.
- Slowing the heart rate
- Acting as vasodilators, causing the muscles around blood vessels to relax.
- Inhibiting an enzyme that causes blood vessels to contract.
Concept Introduction:
Calcium channel blockers are medicines that decrease the blood pressure in patients with hypertension.
Correct answer: b) slowing the heart rate.

An open vessel containing water stands in a laboratory measuring 5.0 m x 5.0 m x 3.0 m at 25 °C ; the vapor pressure (vp) of water at this temperature is 3.2 kPa. When the system has come to equilibrium, what mass of water will be found in the air if there is no ventilation? Repeat the calculation for open vessels containing benzene (vp = 13.1 kPa) and mercury (vp = 0.23 Pa)
Every chemist knows to ‘add acid to water with constant stirring’ when diluting a concentrated acid in order to keep the solution from spewing boiling acid all over the place. Explain how this one fact is enough to prove that strong acids and water do not form ideal solutions.
