Which of the following situations is most favorable for solubility? View Available Hint(s) Which of the following situations is
bixtya [17]

Answer:

strong attraction of solute particles to solvent particles

Explanation:

Solubility occurs when the solute-solvent attraction is more than the solute-solute and solvent-solvent interactions.

<u>A solute solubles in the solvent when the solute solute interactions and the solvent solvent interaction decreases and there is more strong interaction of the solute particles to the solvent particles. </u>

A sample of 5 moles of gas is held at a constant temperature of 500 k inside a container with a volume of 0.25 l. What pressure
pshichka [43]

Answer: 41 atmosphere

Explanation:

Given that:

Volume of water V = 0.5 L

(since 1 liter = 1dm3

0.5L = 0.5dm3)

Temperature T = 500K

Pressure P = ?

Number of moles of gas = 5 moles

Note that Molar gas constant R is a constant with a value of 0.0082 ATM dm3 K-1 mol-1

Then, apply ideal gas equation

pV = nRT

p x 0.5dm3 = 5 moles x (0.0082 atm dm3 K-1 mol-1 x 500K)

p x 0.5dm3 = 20.5 atm dm3

p = (20.5 atm dm3 / 0.5dm3)

p = 41 atm

Thus, the gas is under a pressure of 41 atmosphere

What is a result of the unequal electron sharing in a water molecule?
Katarina [22]

Answer:

The right choice is  c. Water molecules have a weakly positive hydrogen end.

Explanation:

The unequal sharing of electrons in water molecule gives a slight negative charge near its oxygen atom ( see image below) and a slight positive charge near its hydrogen atoms. A neutral molecule that has a partial positive charge at one end and a partial negative charge at the other, it is a polar molecule.

so

a. Water molecules have a nonpolar bond.

It is wrong choice because water has polar bond .

b. Water molecules have a weakly positive oxygen end.  

Also, a wrong choice due to water molecule gives a slight negative charge near its oxygen atom.

c. Water molecules have a weakly positive hydrogen end.  

This is the right choice.

d. Water molecules have two oxygen and two hydrogen atoms

It is wrong choice because water has one oxygen and two hydrogen atoms

<u>So, the right choice is</u>

c. Water molecules have a weakly positive hydrogen end.

How does the angle the light makes with the surface affect the results?<br> not really chemistry
jasenka [17]

Answer:

It is at the greater angle (higher solar elevation) that the surface area receives the most energy because the rays are spread out less. ... The smaller the elevation angle (30°, 20°, 10°) the less energy received per square centimeter, because the rays spread out over a greater area.
