Describe a solution and tell if the parts are mixed chemically or physically.
ANTONII [103]
Hey there! Let's get that problem solved! 

First: Let's define, "solution." 

Solution: <span>a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent).

Next: Ask yourself, "can a solution be taken apart?" 

In some cases, yes. It can. 

The solution of salt water for example, can be physically separated by evaporation. (place salt-water in a pot on a heated stove, place the cover to the pot on the opening, wait a few minutes, remove the top, and you can (and taste) the water without the salt!)  </span><span />

calculate the volume that will be occupied by 350 ml of oxygen measured at 720 mm hg, when the pressure changed to 630 mm hg
likoan [24]

Answer:

406.45mL

Explanation:

The following data were obtained from the question:

V1 = 350mL

P1 = 720mmHg

P2 = 630mmHg

V2 =?

The new volume can be obtain as follows:

P1V1 = P2V2

720 x 350 = 620 x v2

Divide both side by 620

V2 = (720 x 350) /620

V2 = 406.45mL

The new volume of the gas is 406.45mL
