A solute added to a solvent raises the boiling point of the solution because: Select one: a. The solute particles raise the solv

ent's vapor pressure, thus requiring a higher temperature to cause boiling. b. The temperature to cause boiling must be great enough to boil not only the solvent but also the solute. c. The solute increases the volume of the solution, and an increase in volume requires an increase in the temperature to reach the boiling point (derived from PV

Answer:

See the answer below

Explanation:

<em>The correct answer would be that the solute particles lower the solvent's vapor pressure, thus requiring a higher temperature to cause boiling.</em>

Dissolving a solute particle in a solvent leads to a decrease in the vapor pressure of the solvent above the resulting solution when compared to the pure solvent. The lower the vapor pressure of a liquid, the higher the temperature required for the liquid to boil and vice versa. Hence, a higher temperature would be needed to boil a solvent with dissolved solutes.

The polarity of a bond between two elements can be best determined by.
kompoz [17]

The polarity of a bond between two elements can be best determined by difference in the values of electronegativity.

<h3>Determination of polarity of bond</h3>

The polarity of a covalent bond can be determined by determining the difference in electronegativity between the two bonded atoms. Electronegativity is defined as the tendency of an atom to attract electrons to itself.

So we can conclude that the polarity of a bond between two elements can be best determined by difference in the values of electronegativity.

Calculate the formula/molecular mass of following
ddd [48]

Answer:

Refer to the period table. Use the atomic mass for calculation. Multiply the atomic mass with the number of atoms. For example, Al2(SO4)3. (27 × 2) + (32 x 3) + (16 x 12) = molecular mass

sergiy2304 [10]

Yes , I agree with the statement water contains minerals

<u>Explanation:</u>

  • When LaShawna saw the steam, she said that the water must contain a lot of minerals and the statement is true.
  • Most of the water comes from the underground supply and they undergo some cleaning process and stuff.
  • Usually, mineral water comes from natural underground water supply and the springs.
  • Chemical compounds like Calcium, potassium, sodium, iron are present in water.
  • Magnesium plays an essential function in maintaining blood supply and high mineral content water helps us to prevent or lower the heart-related disease.
  • Calcium is the building block for maintaining the bone's health.
