Can you describe how mixtures relate to substances?

Answers

A substance in chemistry is a form of matter consisting having fixed chemical composition (like water). A mixture is a material made up of two or more substances (like water with sugar) - mixed, but not combined with chemical bonding.

A substance is a pure form of matter in which all the constituent particles are the same in their chemical nature, while a mixture is a combination of two or more substances. A substance cannot be separated into other kinds of matter by any physical process. But a mixture can be separated into pure substances by appropriate separation techniques such as filteration, sedimentation, evaporation, crystallisation, etc..

List the steps that show how the sun provides the energy for surface ocean currents?

Answers

1.   The sun’s thermal energy is exhibited from itssurface traveling to the ocean floor in the day
2.   As the heat energy is absorbed by the water, thecurrents move and rise as the ocean waters from the equator heads to the northphase of the planet.
3.   And then the waters from the polar areas headsto the south, while ascending and gushing it becomes heated by the sun.

The sun’s gravity also affects this body of water. Since it has a much more strongergravitation pull than of earth though its far away hence, high tide and low tide tendencies.

The heat moves in predictable ways, flowing from warmer objects to cooler ones, until both reach the same temperature. When air is in contact with the ocean at a different temperature than the sea surface, heat transfer by a conductor. The ocean absorbs and stores energy from the sun and when precipitation falls , it release heat energy in the atmosphere(air)

If the substance entering the cell was in higher concentration inside the cell than outside the cell, what type of transport would be required. Explain your answerA. Active transport B. Passive transport

Answers

If the substance entering the cell was in higher concentration inside the cell than outside the cell, the type of transport that would be required here is known as Active transport. Thus, the correct option for this question is A.

What is Active transport?

Active transport may be defined as a type of transport that occurs against the concentration gradient and therefore it is mediated by carrier proteins. In this type of transport, metabolic energy is utilized in order to move ions or molecules against the concentration gradient. It is directly opposite to passive transport.

Active transport results in the accumulation of solute on one side of the membrane. It is different from the carrier proteins mediated facilitated diffusion. This transport decreases the entropy of the reaction.

Therefore, active transport would be required in order to migrate any substance from a lower concentration to a higher concentration. Thus, the correct option for this question is A.

To learn more about Active transport, refer to the link:

This should be under biology.

To transport the substance inside the cell when the concentration inside the cell is already higher than outside the cell would require active transport because the substance would be moving against its concentration gradient.

Susana heats up a sample of red crystals. While the sample is being heated, a gas is released and a blue powder is left after the heating. Is the sample of red crystals an element or a compound? Explain your answer.

Answers

Answer:

Susana's red crystal sample is a compound because it was broken down into a gas and blue powder. It is not an element because elements cannot be broken down into simpler substances by ordinary means, such as heating.

Explanation:

Final answer:

The red crystals heated by Susana are a compound because they released a gas and turned into a blue powder when heated, indicating a chemical change.

Explanation:

The sample of red crystals that Susana heated up is a compound, not an element. We can come to this conclusion because when the sample was heated, a gas was released and a different substance, a blue powder, was left behind.

This indicates a chemical change had occurred, where the original substance decomposed into different substances. Compounds are known to break down into simpler substances or elements under certain conditions.

An example similar to this would be when blue copper sulfate loses water and becomes white upon heating, or when mercury(II) oxide is heated and decomposes into mercury and oxygen.
