Which factor causes a decrease in the rate of dissolution?
decreasing the amount of solute
increasing the stirring of the solution
decreasing the surface area of the solute
increasing the temperature of the solvent

Answers

Answer 1

Answer:

The correct option of the first option

Explanation:

Dissolution of a solute in a solution is the process in which the solute interacts with the solvent leading to the disappearance of the solute to form a solution. Rate of dissolution is primarily affected by three factors namely

Stirring of the solution: Stirring the solution causes the solute to interact more with the solvent, thus increasing the rate of dissolution.

Surface area of the solute: The smaller the surface area of the solute, the more easier it is for it (the solute) to interact with the solvent. Hence, the smaller the surface area, the faster the rate of dissolution.

Temperature of the solvent: An increase in temperature of the solvent causes the generally causes more things to dissolve in this solvent due to increased energy of molecules in the solvent, which causes the molecules of the solute and solvent to interact more.

A decrease in the amount of solute will reduce the amount of interaction the solute (since it is in lesser quantity) have with the solvent hence the rate of dissolution will also be low (even though a solution will still be formed).

Answer 2

There are different factors that influences chemical equations.  The factor that causes a decrease in the rate of dissolution is decreasing the surface area of the solute.

Dissolution rate is simply known as the transfer rate of some specific drug molecules from the solid particles which is usually crystalline in nature into solution as self free drug molecules. The rate of Dissolution can be determined by the forces of the crystal.

Surface area is known to affect the rate of dissolution.  Note that When the total surface area of the solute particles is increased, the solute will then dissolves more quickly than ever.

The breaking of a solute into smaller pieces in turn do increases its surface area and increases its rate of solution and the act of stirring, do allows the solute to dissolve faster.

Answers

Answer:

Explanation:

A compound that can act both as an acid and a base is called an amphoteric substance. A good example (based on the question) of an amphoteric substance is the Aluminium hydroxide [Al(OH)₃] where Aluminium is the "M" in M-O-H. Aluminium is in the third period of the periodic table. The reaction below shows aluminium can act both as an acid and as a base in different neutralization reactions.

As an acid

Al(OH)₃ + 3NaOH ⇒ Na₃AlO₃ + 3H₂O

As a base

3HCl + Al(OH)₃ ⇒ AlCl₃ + 3H₂O

NOTE: A neutralization reaction is a reaction between an acid and a base to give you salt and water

O It increases.
O It decreases
It fluctuates.
O It remains constant.

Answers

Answer:

It decreases.

Explanation:

As the frequency of electromagnetic waves increases, the wavelength decreases.

What is frequency?

Frequency defines the number of waves passing through a fixed area over a period of time. So if the time we take for the wave to pass is 1/2 second, it is usually 2 per second. If it takes 1/100 of an hour, it is usually 100 per hour.

Iced water.

Explanation:

It's a solid. Within a given substance, such as water, particles in the solid state have the least amount of kinetic energy.

As water freezes, it does so because after thermal energy leaves the particles, the average translational+rotational kinetic energy decreases, but the total average kinetic energy does not... and the temperature does not change either.

Gallium has three valence electrons.

Elements in the periodic table are classified into groups and periods. Elements in a given group have the same number of valence electrons on their outermost shell while the elements in a period have the same number of shells.

All the elements in group 13 have three electrons in their outermost shell. Gallium is an element of group 13. This means that gallium also has three electrons in its outermost shell(valence electrons).

Gallium has 3 valence electrons (1 electron in the 4p orbital and 2 electrons in the 4s orbital) because the valence electrons are those located in the outermost energy level of an atom.

Gallium has an atomic number of 31, which means it has 31 electrons in total. The electron configuration of gallium can be represented as [Ar] 3d¹⁰ 4s² 4p¹.

Within the n=4 shell, gallium has electrons in the 4s and 4p orbitals. The 4s orbital can hold a maximum of 2 electrons, while the 4p orbital can hold a maximum of 6 electrons. In the case of gallium, there is 1 electron in the 4p orbital.

Answers

Answer:

Weight of 14.79 cm rod of iron = 640.51 gram (Approx)

Explanation:

Given:

Weight of 1 inch rod = 3.88 ounce

1 inch = 2.54 centimetre

1 gram = 0.035273 ounce

Find:

Weight of 14.79 cm rod of iron

Computation:

Weight of 14.79 cm rod of iron = 14.79[3.88/{(0.035273)(2.54)}]

Explanation:

During photosynthesis plants absorbs carbon dioxide from the atmosphere and release oxygen into the air. Hence, it increases the level of oxygen for breath.

What is photosynthesis?

Photosynthesis is a biological process by which green plants produce energy and molecular oxygen in leaf by the aid of light energy. The photoactive pigments chlorophyll in green leaves absorbs light energy sufficient for this process.

The photosynthetic reaction involves combination of carbon dioxide and water to form glucose and oxygen as written below:

[tex]\rm 6H_{2}O + 6CO_{2} \rightarrow C_{6}H_{12}O_{6} + 6O_{2}[/tex].
