The osmotic pressure of a solution increases as

2 answers:

5 0

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.

<h2>The answer is option C Explanation: Basically more solute particles will require the solvent to rush in through the semipermeable membrane to fix the high concentration creating a difference in volume between two sides of that membrane. And to even out the volumes on both sides, more (osmosis) pressure will be needed to push down on the solution with higher volume. Anyways, its too confusing to explain, the answer is C and that’s all that matters.</h2>

Vitreous humor is located wear?

Vikentia [17]

Eye

Explanation:

Vitreous humor is found in the human eye and other animals.

It is a gel that fills the space between the lens and retina of the eye. This matter helps to keep the shape of the eye in place by maintaining a constant pressure in the eye.

It is typically made up of water, gelatinous and transparent.

Identify each of the following household substances as a strong electrolyte, weak electrolyte, or non-electrolyte: salt solution

wolverine [178]

Answer:

Electrolytes are substances that can ionize in water. They could be acids, bases or salts as long as they give ions when they dissolve in water.

Explanation:

<em>Strong electrolytes</em> completely ionize when dissolved in water, leaving no neutral molecules. The strong electrolytes here are:<u> salt water</u>, <u>baking soda (NaHCO3) solution.</u>
<em>Weak electrolytes</em> do not completely dissociate in solution, and hence have a low ionic yield. Examples of this would be<u> vinegar </u>and <u>bleach </u>(which could be sodium hypochlorite or chlorine, which are weakly dissociated).
<em>Non-electrolytes </em>will remain as molecules and are not ionized in water at all. In this case, <u>sugar solution is a non-electrolytes</u>, even though sugar dissolves in water, but it remains as a whole molecule and not ions.

What information does the second quantum number of an electron give?

grandymaker [24]

Quantum numbers are the conserved quantities in the system that expresses the position of the electron. The second quantum number describes the electron subshells.

<h3>What are quantum numbers?</h3>

Quantum numbers are the energy and the position defining values of the electron in the atomic structure. There are four basic quantum numbers, principal, magnetic, azimuthal, and spin quantum.

The second quantum number (I) is the angular quantum number that describes the magnitude of the subshells (s,p, d, and f) or the type of the subshells. It is also known as the Azimuthal quantum number.

Therefore, the second quantum number shows the electronic subshells.
