Answer:0.29

Explanation:

To determine the pressure of the hutch on the floor, we must first calculate the area of the base of the hutch.

A=lw=(15in.)(34in.)=510in.2

We can now use the formula to calculate pressure.

P=FAP=150lbs510in.2P≈0.294lbin.2

Rounding to two significant figures, the pressure exerted by the hutch on the floor is 0.29lbin.2.

The ions are able to move freely from one place to another. So that they conduct electricity. But the molecular solutions does not electricity.

The molecular solution is composed of molecules and consists of non - metallic atoms. These atoms are held together by the covalent bonds. The flow of charged particles is responsible for the conduction of electricity. If there is no flow of electrons or ions then there will be no electricity.

In the molecular solutions, the molecules present are not dissociated into respective ions. Since the molecules are not converted into the charged particles no electricity is produced.

A molecular solution is regarded as a non-electrolyte which does not contain ions. But electrolytes are dissociated into ions and thereby conducts electricity. So all electrolytes are good conductors of electricity.

Thus molecular solution does not contain ions.

Answer:

A photon is absorbed by the atom.

Explanation:

In case 2 where an electron jumps from energy level 3 to energy level 9, a photon is absorbed by the atom.

Photon is the basic unit of energy used to describe electromagnetic radiation.

II. A photon is absorbed by the atom.

It is the same scenario as case 2

III. More energy is emitted or absorbed for case 2.

More energy is emitted or absorbed for case 2 because the transition involves movement from a level to a greater level than that of case 1.

Answer:

0.373 M

Explanation:

The reaction is

So 1 mol of acetic acid reacts with 1 mol of sodium hydroxide.

First we calculate the moles of NaOH:

Because the stoichiometric ratio is 1:1 :

Now we calculate the concentration of acetic acid, dividing the moles by the volume:

32.17 mL of 0.116 M NaOH are required to titrate 10.0 mL of 0.373 M acetic acid.

Titration is a common laboratory method of quantitative chemical analysis to determine the concentration of an identified analyte.

Let's consider the neutralization reaction between acetic acid and sodium hydroxide.

HC₂H₃O₂ + NaOH → H₂O + NaC₂H₃O₂

We can calculate the concentration of acetic acid in vinegar using the following expression.

Ca × Va = Cb × Vb

Ca = Cb × Vb / Va

Ca = 0.116 M × 32.17 mL / 10.0 mL = 0.373 M

where,

32.17 mL of 0.116 M NaOH are required to titrate 10.0 mL of 0.373 M acetic acid.

Answer:

Explanation:

Answer:

energy and the equilibrium constant.

The sign of the standard free energy change ΔG° of a chemical reaction determines whether the reaction will tend to proceed in the forward or reverse direction.

Similarly, the relative signs of ΔG° and ΔS° determine whether the spontaniety of a chemical reaction will be affected by the temperature, and if so, in what way.

ΔG is meaningful only for changes in which the temperature and pressure remain constant. These are the conditions under which most reactions are carried out in the laboratory; the system is usually open to the atmosphere (constant pressure) and we begin and end the process at room temperature (after any heat we have added or which is liberated by the reaction has dissipated.) The importance of the Gibbs function can hardly be over-stated: it serves as the single master variable that determines whether a given chemical change is thermodynamically possible. Thus if the free energy of the reactants is greater than that of the products, the entropy of the world will increase when the reaction takes place as written, and so the reaction will tend to take place spontaneously. Conversely, if the free energy of the products exceeds that of the reactants, then the reaction will not take place in the direction written, but it will tend to proceed in the reverse direction.

Answer:

The top left number of the symbol of an atom is the sum of the protons and neutrons in the atom known as atomic mass number, while the bottom left number of the symbol of an atom is the number of protons in the atom known as atomic number.

Explanation:

An atom of an element is composed of other subatomic particles; the electron, proton and neutron. The number of protons present in an atom of an element is equal to the number of electrons present in the atom of that element and is known as the atomic number of the element. The number of neutrons present in the atom summed together with the proton number gives the atomic mass number of an atom of the element.

Elements are represented with symbols. In writing the symbols of elements, the atomic number and the atomic mass of an atom of the element is usually written along with the symbol. The top left number of the symbol of an atom is the sum of the protons and neutrons in the atom, while the bottom left number of the symbol of an atom is the number of protons in the atom.

For example, the element sodium has an atomic number of 11 and a mass number of 23. In symbols, it is written as follows: ²³₁₁Na

It was a cold December night shortly after dusk, a likely setting for an event that would prove to be life altering. As fate would have it, this would be the night that I lost the material possession that truly meant the most to me. I would lose the one thing that gave me much pride and joy and excitement. I often think back and liken us to a newlywed couple, for we had only been together for 18 months and were still very much honeymooning. It was a night, a moment, that even now scoffs and mocks me as I travel thither and yonder with her replacement. But she can never be truly replaced and to call my current fix a replacement seems like a sort of blasphemy.

I called her my Blue Angel. That's right! She was a brand new 1999 Atlantic blue Ford Mustang fully equipped with white racing stripes on each side, dark window tint, a rear spoiler, and a post-factory sound system that I installed personally just to complete the "dream ride" effect. We met on April 24, 1999,when my parents introduced us and told me she was all mine as a reward for graduating high school as valedictorian. And what a reward she turned out to be. We went everywhere together. I took her out to eat. When I'd go play ball somewhere, she went with me. Every day from April 24, 1999, to December 22, 2000, we were together. We were bonding in a way a young man can bond with no other, and there truly was no other for me. Other guys had bigger trucks and faster cars, but where my Blue Angel was lacking in size and power, she more than made up for in pure, unadulterated, raw emotion, She never let me down; she was always looking her best and never longing for attention from me or any of the other countless admirers and fans she won over for...

Explanation:

According to chemistry libretexts(2020); "The rms velocity is directly proportional to the square root of temperature and inversely proportional to the square root of molar mass. Thus quadrupling the temperature of a given gas doubles the rms velocity of the molecules. ... As the temperature of a gas is increased, the velocity of the molecules is also increased."

Hence considering two gases for which the  Vrms of the particles of one is high and that of the other is low, we can conclude that the gas having the higher  Vrms is at a higher temperature than the gas having a lower  Vrms according to the foregoing.
