Surface tension increases by increasing the intermolecular forces.

<h3>What is intermolecular forces?</h3>

The electromagnetic forces of attraction or repulsion that act between atoms and other types of nearby particles, such as atoms or ions, are examples of intermolecular forces (IMFs), also known as secondary forces.

Between molecules, intermolecular forces are at work. In contrast, molecules themselves exert intramolecular pressures. In comparison to intramolecular forces, intermolecular forces are weaker. Intermolecular forces include things like the London dispersion force, dipole-dipole interaction, ion-dipole interaction, and van der Waals forces.

Intermolecular forces come in five flavors: ion-induced dipole forces, dipole-induced dipole forces, induced dipole forces, and dipole-dipole forces. Ions and polar (dipole) molecules are held together by ion-dipole forces.

How many grams of H2O are needed to produce 150 g of Mg(OH)2? (Molar mass: H2O = 18.02 g/mol; Mg(OH)2 = 58.33 g/mol )
Nuetrik [128]

Answer:

92.6

Explanation:

6 mol x 18.02 g of H2o --> 3 mol x 58.33 g  Mg(OH)2

108.12 g of h2o --> 174.99 of Mg(OH)2

g of H2O is 150 g of Mg(OH)2

150g x 108.12g / 174.99 =

Which of the following a true statement about igneous rocks?
Marta_Voda [28]

Answer:

i think the answer is A....

Explanation:

Igneous rocks (from the Latin word for fire) form when hot, molten rock crystallizes and solidifies. The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface.

Choose the solvent below that would show the greatest freezing point lowering when used to make a 0.20 m nonelectrolyte solution
tatiyna

Answer : Carbon tetrachloride, k_f=29.9^oC/m will show the greatest freezing point lowering.

Explanation :

For non-electrolyte solution, the formula used for lowering in freezing point is,

\Delta T_f=k_f\times m

where,

\Delta T_f = lowering in freezing point

k_f = molal depression constant

m = molality

As per question, the molality is same for all the non-electrolyte solution. So, the lowering in freezing point is depend on the k_f only.

That means the higher the value of k_f, the higher will be the freezing point lowering.

From the given non-electrolyte solutions, the value of k_f of carbon tetrachloride is higher than the other solutions.

Therefore, Carbon tetrachloride, k_f=29.9^oC/m will show the greatest freezing point lowering.
