Stirring this is because the three elements are factors affecting dissolving of a solvent. Eg temprature affects in hotness or coldness, Particle size affects whether it is big or small while quantity of soluble affects by the amount

Answer: The answer is B. Particle size of the solvent

Explanation: Solvent is usually in a liquid state (or sometimes in gaseous or solid-state). It is used in dissolving solutes (which are usually in solid-state). Although, the solute can also be in the form of a liquid and gaseous state.

When a solute dissolves in a solvent, a solution is formed. An example is when you have a salt (solute) dissolved in water(solvent) it will form a saline solution( which of course is the solution).

Factors that determine the rate a solute dissolves in a solvent include; temperature, stirring, the particle size of solute, the quantity of solute.

Temperature affects the rate of dissolving because, in a warmer solvent, solute has more energy to move compared in a cool solvent.

Stirring helps in the distribution of a solute in a solvent. When u agitate or stir, the solute will dissolve faster in the solvent.

The particle size of solute affects the rate of dissolving because a smaller particle size of a solute will dissolve faster than a solute with larger particle size.

Quantity of solute can also be a factor because when you have different quantities of solutes in a particular quantity of the same solvent, the rate of dissolving will be different provided they undergo the same factors I.e the solute with higher quantity will dissolve slower compared to the solute with less quantity provided the solvent is in the same temperature state.

Since solvents are usually in a liquid state, the particle size of the solvents won't be a factor of the rate at which the solutes will dissolve.

Explain the two main physical/ chemical processes by which carbon dioxide molecules in the air move to the cells of phytoplankto
VARVARA [1.3K]

Answer:

The two physical/ chemical processes by which carbon dioxide molecules in the air move to the cells of phytoplankton in the ocean are the photosynthesis and the biological carbon pump.

Explanation:

The biological carbon pump is the action of organisms to move carbon during chemical and biological interactions from the surface into the deeper ocean and then to rocks.  

The biological carbon pump its composed of three processes, which are the photosynthesis, the gravity and the food web interactions. They are all part of the carbon cycle.

During the photosynthesis, the phytoplankton take up carbon dioxide from the atmosphere that is dissolved in the surface water, and receives the energy from the sun to turn it into glucose and oxygen.  

In the cells of the phytoplankton, glucose is transformed into other organic compounds. This material has organic carbon that can end in two ways: it is incorporated to marine organisms during the food web interactions or it can be remineralised forming calcium carbonate in the ocean surface.  

The remineralization can be done by many organisms to build its shells or skeletons, or by chemical processes that happen in the ocean. This process allows more carbon dioxide to enter the water and to continue the cycle.

So when marine organisms die, all its organic components sink into the bottom of the ocean and carbon-rich sediments are form. And after millions of years, these sediments turn into rocks after going through chemical and physical phenomenon.

Which of the following is most likely an indication of a chemical change?
mamaluj [8]

Hello there!

Question: Which of the following is most likely an indication of a chemical change?

Answer Choices:

A. A loud sound when an MP3 player is turned on.

B. A loud sound when someone claps their hands.

C. A loud sound when a starter's pistol is fired at a race.

D. A loud sound when a large object falls to the ground.

Correct Answer:

C. A loud sound when a starter's pistol is fired at a race.

Reasons:

A would not be correct since an MP3 player is a mechanical object and does not mix any substances that create a reaction.

B would not be correct since clapping hands causes a loud sound due to two forces slamming together and causes a disturbance in the air.

D would not be correct since a large object falling to the ground does not indicate any chemical reactions or changes since its merely the result of a mass hitting another mass.

C would be correct since the gunpowder mixes with other substances inside the pistol's chamber and causes and explosion, and explosions are part of a chemical reaction indicators.
