11) What volume will 0.75 mol of Oxygen gas (O2) occupy at 298 K and a pressure of 52.7 kPa?

Answers

Answer:

Volume = 35.3L

Explanation:

Use Ideal Gas Law (PV=nRT) and isolate for V (volume) by dividing both sides by P (pressure). You will then get the eqaution listed below and you can solve by using the method I used below.

V = nRT/P

V = (0.75kPa)(8.314)(298K)/(52.7kPa)

V = 1858.179/52.7

V = 35.3L

Which method is used to obtain common salt from rock salt? Why?

Answers

Rock salt or halite is a mineral the contains sodium chloride (table salt) as well as other minerals and impurities. You can remove most of these contaminants using two simple purification techniques: filtration and evaporation.

Materials
Rock salt
Water
Spatula
Filter paper
Funnel
Evaporating dish
Beaker or graduated cylinder
Tripod
Bunsen burner
Filtration
If the rock salt is one large chunk, grind it into a powder using a mortar and pestle or a coffee grinder.
Add 30-50 milliliters of water to six heaping spatula scoops of rock salt.
Stir to dissolve the salt.
Place the filter paper in the mouth of the funnel.
Place the evaporating dish under the funnel to collect the liquid.
Slowly pour the rock salt solution into the funnel. Make sure you don't over-fill the funnel. You don't want the liquid to flow around the top of the filter paper because then it isn't getting filtered.

why compounds with weak molecular forces are usually gases.

Answers

Molecular substances tend to be gases because the intermolecular forces of attraction are comparatively weak. You don't have to break any covalent bonds in order to melt or boil a molecular substance.

The longest intermolecular separation and hence the strongest intermolecular pressure of attraction can be found in the gaseous state of matter.

Although solids' intermolecular interactions were sufficient to maintain themselves in locked places, gases often have weak intermolecular forces that cause them to remain considerably separated. The gases possess greater intermolecular space than solids as a result of these weak forces.
