Do molecules move in a liquid?

Answers

Answer 1

Answer:

Answer:

Yes.

Molecules always move in most objects, but in solids, they are extremely slow. Liquids move slower than gases, but move more than solids.

Answer 2

Answer:

Final answer:

Molecules do move in a liquid, as they are free to slide past each other and change neighbors due to their mutual attraction. This allows liquids to flow and take the shape of their containers. The speed of this movement can depend on the mass of the molecules - lighter ones move and diffuse faster.

Explanation:

Yes, indeed, molecules do move in a liquid. This is due to the fact that liquids are typically in a more energetic state in which their particles can slide past one another and change neighbors. However, these particles remain closely held together by their mutual attraction which maintains the liquid's lack of shape conformity.

In liquids, unlike solids, the atoms or molecules are free to move around, which contributes to them being classified as a type of fluid. Due to their capacity to flow and rearrange their molecular structure, liquids deform easily when under stress. Once the force is removed, they don't return to their initial form, which is evidenced when a liquid takes the shape of a container it's put in.

Finally, the movement of these molecules is also somewhat dependent on their mass. Heavier molecules tend to move slower and are therefore slower to diffuse. In contrast, lighter molecules tend to move and diffuse faster.

This reaction is an example of what type of reaction? H2SO3(aq) H2O(l) + SO2(g)a. a synthesis reaction
b. a disynthesis reaction
c. a combustion reaction
d. a decomposition reaction

Answers

This reaction H2SO3(aq) H2O(l) + SO2(g) is an example of what a decomposition reaction. It is not a replacement reaction because no other compound is involved. It is not a combustion reaction because no oxygen is involved.

Answer: Option (d) is the correct answer.

Explanation:

A chemical reaction in which a compound dissociates to give two different compounds or atoms is known as a dissociation reaction.

For example, $H_(2)SO_(3)(aq) \rightarrow H_(2)O(l) + SO_(2)(g)$

Here, sulfurous acid dissociates into water and sulfur dioxide gas. Both water and sulphur dioxide have different properties than sulfurous acid.

Therefore, we can conclude that the given reaction is an example of a decomposition reaction.

Please Help meHello guys,i really need your help for a few questions about the greek philosopher "Democritus"
1)revisions that were made to Democritus's model once further research was done.
2)one challenge that the scientist had to overcome.

please help me

Answers

Democritus was the first to propose the idea of the atom. He said the atom was just this tiny, solid sphere. However, he used no scientific evidence to support his claim, so a guy named John Dalton did some experimenting and basically backed up Democritus' claim with evidence. Then, a guy named J.J. Thompson came along and said the atom was not solid and that is consisted of tiny negatively charged particles(electrons) and he came up with the Plum Pudding model which is just a tiny sphere with a punch of random scattered dots in it. After that, Ernest Rutherford did experiments and found that the tiny sphere is made up of mostly empty space with a tiny, dense, positively charged sphere inside of it, and the negatively charged particles just randomly float around it. Neils Bohr then said that the electrons take specific, circular, evenly spaced paths. Then, finally, we come to the Quantum Mechanical Model which is the one accepted today. This model basically vetos Bohr's idea and has a nucleus inside of an electron cloud, which is where the electrons are found.

A 1.00 L volume of HCl reacted completely with 2.00 L of 1.50 M Ca(OH)2 according to the balanced chemical equation below. 2HCl + Ca(OH)2 > CaCl2 + 2H2O What was the molarity of the HCl solution?it is either 6.00 M or 0.375 M

Answers

The first step is to find the number of moles of OH⁻ that reacted with the HCl. To do this multiply 2.00L by 1.50M to get 3 moles of Ca(OH)₂. Then you multiply 3 by 2 (there are 2 moles of OH⁻ per every 1 mole of Ca(OH)₂) to get 6 moles of OH⁻. That means that you needed 6 moles of HCl since 1 mole of HCl contains 1 mole of H⁺ and equal amounts H⁺ and OH⁻ reacted with each other. To find the molarity of the HCl solution you need to divide 6mol by 1L to get 6M. Tat means that the concentration of the acid was 6M.

I hope this helps. Let me know if anything was unclear.

Explanation:

Mintu wants to increase the heat transfer between a metal iron and another piece of metal he wants to shape. He decides to increase the time the two metals are in contact, use a larger metal iron, and use a new metal material with a higher specific heat. Where is Mintu's error?A:Mintu should have decreased the size of the metal iron
B:Mintu should have decreased the time he touches the two metals
C:Mintu should have chosen a material with a lower specific heat
D:Mintu should have chosen a material the same temperature as the iron.

Answers

Answer: Option (C) is the correct answer.

Explanation:

The amount of heat necessary to raise the temperature of 1 gram of a substance by $1^(o)C$ is known as specific heat of a substance.

Mathematically, q = $mC \Delta T$

where, q = Heat energy

C = specific heat

$\Delta T$ = change in temperature

Hence, smaller is the amount of heat required by a substance to raise the temperature of its 1 g by $1^(o)C$ more readily it will get hot.

Therefore, out of the given options specific heat of copper is small. So, copper will heat up quickly.

Thus, we can conclude that Mintu's error is that Mintu should have chosen a material with a lower specific heat.

Answer:

C - Mintu should have chosen a material with a lower specific heat.
