A sample of oxygen gas occupies a volume of 250 mL at .8 atm of pressure. What volume will it occupy at 1.2 atm of pressure?

Answers

167 mL

P1V1 = P2V2
P1 = .8 atm
V1 = 250 mL
P2 = 1.2 atm

Solve for V2 —> V2 = P1V1/P2

V2 = (0.8 atm)(250 mL) / (1.2 atm) = 167 mL

a solution is prepared by dissolving 55g of CaCl2 into 300g of water. if the Kf of water is -1.86 c/m, shat is the freezing point depression of the solution

Answers

Answer:

Relation between , molality and temperature is as follows.

                T =

It is also known as depression between freezing point where, i is the Van't Hoff factor.

Let us assume that there is 100% dissociation. Hence, the value of i for these given species will be as follows.

         i for  = 3

          i for glucose = 1

          i for NaCl = 2

Depression in freezing point will have a negative sign. Therefore, d

depression in freezing point for the given species is as follows.

       

                 =

       

                  =

     

                   =

Therefore, we can conclude that given species are arranged according to their freezing point depression with the least depression first as follows.

                    Glucose < NaCl <

Describe how you plan to design, build, and test a travel cup that uses thermal insulators?

Answers

The statement is "thermal insulators of a double-layered vacuum seal make a liquid heated when it's cold and keep it cool when it's hot."

What is thermal insulator?

A thermal insulator is a material that inhibits heat from being conveyed from one location to another.

Campers seek a travel cup that cools liquids with a cold pack. Design the exterior portion of the cup to keep the drink cold after it has cooled down, as well as the interior compartment to contain the cold pack and channel heat from the liquid in the cup. One of the greatest ways to keep your coffee hot for a long time is to use vacuum insulation in a thermos. On the surface, the concept appears straightforward.

 why don't we ever see solid or liquid oxygen on earth?

Answers

Please mark me brainiest!

The reason why you don’t see solid or liquid oxygen is because oxygen is a natural occurring gas. Gas can not be solid or liquid because there is too much energy to have volume/shape. That’s why you see oxygen tanks, as the tank keeps the gas contained and that is why you can’t see it in the air outside or in something like H20 (water).
