The nature particle model of matter describe the property of solid, liquid and gas in molecular level. Which of the given statem
dangina [55]

Answer:

B. Particles of matter have spaces between them.

Explanation:

The particle nature model of matter is an model used to explain the properties and nature of matter. The statements of the particle nature model of matter are as follows :

1. Matter is made of small particles of atoms or molecules.

2. The particles of matter have space between them. The spaces between the particles are least in solids as they are closely packed together but are greatest in gases whose particles are far apart from each other.

3. The particles of matter are in constant motion at all times. Solids particles are not free to move due to strong molecular forces between the particles, but are constantly vibrating in their mean positions. Liquid particles free to move due to lesser molecular forces while gas molecules which have negligible intermolecular forces have the greatest ability to move.

4. The particles of matter are attracted to each other by intermolecular forces. These forces are greatest in solids and least in gases.

The correct option is B.

What are atoms made of
fomenos

Atoms are made of subatomic particles known as protons, neutrons, and electrons.

(Small bonus: in order to mimic the technology of replicators like in star trek, you need to mess with protons, neutrons, and electrons) (pls dont report)

Match the specific enzyme to its class. A. oxidoreductase B. hydrolase C. transferase D. ligase E. lyase aminase
lilavasa [31]

Answer: Every enzyme has a specific name that can give us insight into the specific reaction that that enzyme can catalyze. We divide them into six different categories.

1) Oxidoreductase - includes two different types of reactions by transferring electrons from either molecule A to B or vice versa. It is involved in oxidizing electrons away from a molecule.

2) Hydrolase - uses water to divide a molecule into two other molecules.

3) Transferase - you move some functional group X from molecule B to molecule A

4) Ligase - catalyzes reactions between two molecules, A and B, that are combining to form a complex between the two. (example: DNA replication)

5) Lyase - divides a molecule into two other molecules without using water and without reducing or oxidation

Pls help ASAP........ A student was roasting marshmallows over a fire. The student
Phantasy [73]

Answer:

A chemical change

Explanation:

The marshmallow turning brown and bubbling implies that a chemical change has taken place.

For chemical changes to occur, we observe any of the following:

  • a new kind of matter is formed.
  • it is always accompanied by energy changes
  • the process is not easily reversible
  • it involves a change in mass
  • requires considerable amount of energy.

ii. Two signs that shows a chemical change has taken place is that:

  • bubbles are being formed as it is roasted and it implies that new substances have been formed.
  • also, significant amount of heat energy is supplied for the roasting.
