Answer
There is nothing like viscosity in solid because most of the solids usually have a rigid body. This is due to strong intermolecular forces. And it is due to this strong force between the molecules that they are unable to move and they remain fixed at their position. Some solids such as graphite which have layered structure, don't possess the property of viscosity, because of the strong force between the layers.
Explanation:
Viscosity is the property of a fluid that opposes the relative motion between two surfaces of the fluid that are moving at different velocities. In simple terms, viscosity means friction between the molecules of fluid.
FOR EXAMPLE
water is "thin", having a low viscosity, while vegetable oil is "thick" having a high viscosity
5. What do the data in your graphs tell you? Explain in one or two sentences what trend the reader should observe in each of your graphs. (Science Lab Report, if you don't know what the answer is please don't answer-)
Answer:
Graphs are a common method to visually illustrate relationships in the data. The purpose of a graph is to present data that are too numerous or complicated to be described, and If the data shows pronounced trends or reveals relations between variables, a graph should be used.

Explanation:
Given data:
Initial volume V₁ = 318 mL
Initial molarity M₁ = 5.75 M
New volume V₂= 461 mL
New concentration M₂= ?
Solution:
New volume V₂= 143 mL+ 318 mL
New volume V₂= 461 mL
Formula:
M₁V₁ = M₂V₂
M₂ = M₁V₁ / V₂
M₂ = 5.75 M × 318 mL / 461 mL
M₂ = 1828.5 M. mL/ 461 mL
M₂ = 3.97 M

Which of the following is true with respect to energy in a closed system?
A.
Energy can be destroyed, but cannot be created.
.
Energy can be created, but cannot be destroyed.
B.
OOOO
C. The system's kinetic energy must equal its potential energy.
D.
The total amount of energy in the system always stays the same.
Answer:
D. The total amount of energy in the system always stays the same
Explanation:
In the closed system, the total amount of energy in the system always stays the same.
What is closed system?Closed system is a arrangement in which exchange of energy or any material is restricted.
If any reaction is carried out in a closed system then energy of the system may convert from internal energy to potential or from potential to kinetic energy. But the total energy of the closed system is always remain same as before and after the reaction.
Hence option (D) is correct.

A high school chemistry teacher asks four student groups to determine the number of protons, neutrons, and electrons (respectively) present in an ion of Titanium (Ti 2+). Which student group provides the best answer?
Answer:
Electrons - 20
protons - 22
neutrons - 26
Explanation:
Titanium has an atomic number of 22 indicating that the neutral atom has 22 protons.
Ti 2+ has lost two electrons and contains only 20 electrons, 22 protons.
The mass number of titanium is 48. Hence;
Mass number = atomic number + number of neutrons
Since the atomic number is 22 and the mass number is 48
number of neutrons = 48 - 22 = 26 neutrons

Two sphericle objects have masses of 8000 KG and 1500 KG their centers are separated by a distance of 1.5 M find the gravitational attraction between them
if I am correct I think its I'm am not 100 percent sure but I think this should be the answer
The gravitational force of attraction between them is 3.56 * 10⁻⁴ N
Using the formula of gravitational attraction
F = G*M1M2/d²
where G = 6.67 * 10⁻¹¹ Nm²Kg⁻²
M1 = 8000Kg
M2 = 1500 Kg
F = 6.67 * 10⁻¹¹ * 8000 * 1500 / (1.5)²
F = 3.56 * 10⁻⁴ N
The gravitational force of attraction between them is 3.56 * 10⁻⁴ N

How can the gravitational potential energy of an object be changed?
Answer:
Gravitational potential energy may be converted to other forms of energy, such as kinetic energy. If we release the mass, gravitational force will do an amount of work equal to mgh on it, thereby increasing its kinetic energy by that same amount (by the work-energy theorem).

Where else have you heard the term conservation? How does the term's meaning in that other context relate to its meaning in chemistry? please help me im so confuseddd
Answer:
See the answer below
Explanation:
Conservation is also a topic in Biology and it refers to the practice of managing natural resources - both living and non-living - with the aim of preserving them to secure the future of the human population.
Conservation in Chemistry refers to the property of chemical reactions in which no new matter or energy is created nor destroyed during the course of the reactions, although they can be converted from one form to another.
Conservation in Biology and Chemistry can be likened to each other based on the fact that both deal with preservation. While conservation in Biology focuses on how the ecosystem can be preserved, conservation in Chemistry deals with the preservation of matter/energy.

Why are ions usually formed during the interaction of metal with nonmetal and not between two metals?
Explanation:
Ions are always formed when metals and non-metals interact because metals are electropositive. They willing release electrons to non-metals that are electronegative.
This activity results in charge separation. The transfer of electrons from one specie to another is what results in an ionic bond and the precedence of charged particles.
Between non-metals, the electrons are jointly shared. Therefore, there is no charge separation.
