A compound is considered a pure substance meaning there is only one type of particle in the substance. A mixture is a combination of two or more different chemical pot compound or an element or substances. It is not a pure substance but I combination of multiple particles
B.two or more atoms of one or more elements that are linked by shared electrons<span>
C. pure substance</span> <span> D. can be found in elements and compounds</span>
The osmotic pressure of a solution is a colligative property, which means that it depends on the number of particles of solute in the solution.
Formula: Osmotic pressure = MRT, where M is the molarity of the solution, R is the universal constant of ideal gases and T is the absolute temperature of the solution.
So, the answer is the option .: the osmotic pressure of a solution increases as the number of particles of solute in the solution increases.
Answer:
At the higher altitude, the new volume is 750.2L
Explanation:
If we decompose the Ideal Gases Law for the two situations (initial and final), we can determine this relaion:
P₁ . V₁ / T₁ = P₂ . V₂ / T₂
Number of moles does not change, and R stays the same.
Let's make some conversions, before:
752 mmHg . 1 atm / 760mmHg = 0.989 atm
24.3°C + 273 = 297.3K
0.0708 bar . 0.986 atm / 1bar = 0.070 atm
-5.41°C + 273 = 267.59 K
We replace: (0.989 atm . 59L) / 297.3K = (0.070 atm . V₂) / 267.59K
[(0.989 atm . 59L) / 297.3K] . 267.59K = 0.070 atm . V₂
52.5 atm.L = 0.070 atm . V₂
V₂ = 52.5 atm.L / 0.070atm = 750.2L
