Answer:
No
Explanation:
The gas will have more volume compared to the liquid.
Gases have no definite shape and no volume. They simply assume the shape of any container they are placed into. They will fill up the entirety of the bottle they are placed into.
Liquids have fixed volume although they do not have fixed shape. As they are held with weak intermolecular interactions, they are limited in space.
Therefore, they will maintain that initial volume at which they were introduced into the container.
Liquids generally have a fixed volume and gases do not.Which statement best explains the energy change that will occur when the

SUBMIE
Answer:the answer is D
Explanation:
I have already taken the exam. Hope this helps
The kinetic energy of the ball is transmitted to the catcher's mitt and the total energy remains conserved.
What is Energy?It is defined as the capability of a body for doing work. Its SI unit is joules. Example - Kinetic energy, potential energy, heat energy etc.
Given is that a ball hits the catcher's mitt.
Now, when ball is in the motion in the air than it is moving with some velocity. Assume that velocity to be v m/s. Then, its kinetic energy will be -
E[K] = 1/2mv²
Therefore, it has kinetic energy. Now as the ball is caught by the player, the ball stops and its kinetic energy is transmitted into the player's mitt. From law of conservation of energy
E[K] + E[mitt] = E[mitt] + E[K]
1/2mv² + 0 = 1/2mv² + 0
So the energy is conserved and transferred.
Thus, the kinetic energy of the ball is transmitted to the catcher's mitt.
Therefore, the kinetic energy of the ball is transmitted to the catcher's mitt and the total energy remains conserved.

4. Answer, Like gases, plasmas have no fixed shape or volume, and are less dense than solids or liquids. But unlike ordinary gases, plasmas are made up of atoms in which some or all of the electrons have been stripped away and positively charged nuclei, called ions, roam freely.
5. Answer The energy associated with an object's motion is called kinetic energy. A speeding bullet, a walking person, and electromagnetic radiation like light all have kinetic energy. Another example of kinetic energy is the energy associated with the constant, random bouncing of atoms or molecules.
6.Answer is solid
Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy. The temperature of a substance is a measure of the average kinetic energy of the particles.
7. Answer Water behaves differently to most other substances because, in its solid state (ice), its particles are less densely packed than in its liquid state. This is why ice floats.
8. Answer 212 degrees F.
Sea Level: Water boils at 212 degrees F. and simmers at 190 degrees F.
9. Answer When an object is heated the motion of the particles increases as the particles become more energetic. If it is cooled the motion of the particles decreases as they lose energy.
10. Answer CHEMISTRY TERM PHASE CHANGE

11. Answer is Energy is consumed (endothermic) to melt ice (solid to liquid) so the opposite process (liquid to solid) must be exothermic.
12.In simple terms, the endothermic reactions absorb energy from the surrounding that is in the form of heat. On the other hand, an exothermic reaction releases energy into the surrounding of the system.

f the solubility of sodium chloride (NaCl) is 30.6 g/100 mL of H2O at a given temperature, how many grams of NaCl can be dissolved in 250.0 mL of H2O
Answer:
76.5 grams
Explanation:
Solubility of sodium chloride = [tex]\dfrac{30.6}{100}=0.306\ \text{g/mL}[/tex]
Now volume of water is 250 mL
We have to find the amount of NaCl that can be dissolved in the above mentioned amount of water
Let the mass of NaCl that can be dissolved be m so
[tex]\dfrac{m}{250}=0.306\\\Rightarrow m=250\times0.306\\\Rightarrow m=76.5\ \text{g}[/tex]
The mass of NaCl that can be dissolved is 76.5 grams.
which element exists as a diatomic molecule at STP
The elements with standard temperature ,pressure, are the diatomic molecules like hydrogen, nitrogen, chlorine and oxygen.
What is diatomic molecule ?Two atoms are chemically linked in order to create diatomic molecules. They make up a homonuclear diatomic molecule if the two atoms are the same, such in the oxygen molecule (O2), for example in the case. If the atoms are different.
Diatomic molecules are two-atom-only molecules, which can contain the same or different chemical components. A diatomic molecule is a structure made up of two atoms that were already connected together. Examples include carbon monoxide, oxygen, nitrogen, and hydrogen (H2) (CO).

Fusion breaks apart nuclei; fission puts them together. Fission breaks apart nuclei; fusion puts them together. Fission and fusion have identical reactions.
Answers:
Fission breaks apart nuclei
Fusion puts them together.
======================================================
Explanation:
The term "fission" is related to the term "fissure" which means "a cut or divide", often describing a geologic feature of the earth (eg: a crack in the rock).
Fusion is the idea of putting things together, which is the opposite of fission. The term doesn't have to apply to nuclear fusion. It could be something like the fusing of two ideas to create one new idea.

calculate the percent by mass of 4.35g of Na I dissolved in 105g of water
We are given:
Mass of Na added = 4.35 grams
Mass of water = 105 grams
Mass Percent of Na:
Total mass of the solution = mass of solute + mass of solvent
Total mass of the solution = 4.35 + 105 = 109.35 grams
Mass percent of solute = (mass of solute / mass of solution) * 100
Mass percent of Solute = (4.35 / 109.35) * 100
Mass percent = 3.978 %

Can someone please tell me the answer
Answer:
52.068 amu
Explanation:
To calculate the average atomic mass of chromium, you have to first multiply the abundance of an isotope with its mass.
49.946 × 0.0435 = 2.173
51.941 × 0.838 = 43.527
52.941 × 0.0235 = 1.244
53.939 × 0.095 = 5.124
Next, add up all of the values, and you will get the average atomic mass.
2.173 + 45.527 + 1.244 + 5.124 = 52.068 amu
In the following reaction, which species is reduced? Au(s) + 3NO3-(aq) + 6H+(aq) → Au3+(aq) + NO(g) + 3H2O (l) H+ N+5 O2- H2O Au
Answer:
NO3-
Explanation:
Given the reaction equation;
Au(s) + 3NO3-(aq) + 6H+(aq)→Au3+(aq) + 3NO2(g) + 3H2O (l).
We can consider the oxidation states of species on the left and right hand sides of the reaction equation;
Au is in zero oxidation state on the left hand side and an oxidation state of +3 on the righthand side.
NO3- is in oxidation state of +5 on the righthand side and NO2 is in + 4 oxidation state.
H+ is in + 1 oxidation state on both the left and right hand sides of the reaction equation.
Since reduction has to do with a decrease in oxidation number, it follows that NO3- was reduced in the reaction.
A 26.9 g rock rolls down the Hill at a speed of 81.9 m/s. what is the kinetic energy of the rock?
Answer:
90.21 J
Explanation:
Given that,
Mass of a rock, m = 26.9 g = 0.0269 kg
Speed of the rock, v = 81.9 m/s
We need to find the kinetic energy of the rock. It can be calculated using the formula as follows :
[tex]E=\dfrac{1}{2}mv^2\\\\E=\dfrac{1}{2}\times 0.0269\times 81.9^2\\\\E=90.21\ J[/tex]
So, the kinetic energy of the rock is 90.21 J.

London dispersion forces
van der Waals forces
hydrogen bonds
covalent bonds
Answer:
D) Covalent Bonds
Explanation:
Quizlet says so
Among the given options the intramolecular force is covalent bonding. Covalent bond is formed between two nonmetals by sharing of electrons. All other given forces are intermolecular.
What is covalent bonding ?A covalent bond is formed between two non-metals through sharing of valence electrons between atoms. For example carbon and oxygen are non metals forming the covalent compound CO.
The number of shared pair of electron depends on the valence of each atoms. For example in HCl, both atoms shares one electron to each other.
In a covalent compound, if the difference in electronegativity between two atoms is significant, the shared pair of electrons attracts towards the highly electronegative atom and resulting charge separation make them polar compounds.
