Which of the following statements about gas
solubility in liquids is false?
a. Most gases that are soluble in water are polar or react
b. Gas, liquid solid formation is always endothermic.
c. Gases are more soluble under high pressure than under low
d. Gas solubility decreases with increasing temperature.
e. A carbonated beverage will go flat more slowly in the
my guess C
Which of the following is the most
appropriate explanation of the following observation “hydrogen chloride gas HCL,
is very soluble in water”
Polar solutes dissolve in non-polar solvents and vice versa
Water is a
polar solvent and it promotes the ionization of many polar molecules
the dissociation of many ionic solids
interact only slightly with solvents dissolve freely
weight molecules are generally more soluble in water than heavier molecules

c. 1M sucrose C12H10O11
d. 1M MgCl2
e. 1M sulfuric acid H2SO4
my guess C
