By increasing the temperature of the solvent, the movement of molecules speed up resulting in the more movement of particles and they bump into each other more vigorously. As a result of that, the particles of the solute break faster and dissolve in the solvent faster.

<u>Answer: </u>As the temperature increases, the rate of formation of solution increases.

<u>Explanation:</u>

Solvent is defined as a substance which is present in larger proportion in a solution. Solute is dissolved in the solvent to form a solution.

As, the temperature of the solvent increases, the kinetic energy of the particles of solvent increases and the intermolecular spacing between the solvent particles increases and therefore, this results in the more dissolution of the solute particles in the solvent and hence, the formation of solution increases.

Therefore, there is a direct relationship between the temperature of the solvent and the formation of the solution.

alisha [4.7K]

Explanation:

1.

i. Measure the initial volume of water in a graduated cylinder.

ii. Now submerge the irregularly shaped metal into water in a graduated cylinder.

iii. Measure the final volume of water.

iv. The difference between the final volume and the initial volume is the volume of the irregularly shaped metal.

2.

When adding the irregularly shaped metal into the glass graduated cylinder. Make sure that the irregularly shaped metal is completely submerged into the water.

What is the precent yield if the actual yield is 25g and 100g should have formed?
11Alexandr11 [23.1K]

Answer:

Percent yield is 25%

Explanation:

Information given is

Actual yield is 25 g

But the yield should be 100 g

The percent yield is defined as the ratio of the actual yield and the predicted yield it means that out of the predicted yield what percentage of the actual yield is obtained

∴ Percent yield = (Actual yield ÷ Predicted yield) ×  100

In case of the given problem the percent yield will be

(25÷100) × 100 = 25%

∴ Percent yield = 25%
