Answer: a responsibilty

Explanation:

An obligation to do something or control over or care for someone. ​The word suitable for it is "responsibility".

An obligation is a duty or responsibility to do anything that is required by law, custom, or moral standards.

Responsibility is an obligation to do something or control over or care for someone. It is a duty or task that one is required to undertake.

Responsibility can be of different forms, such as personal, social, or professional.

Personal responsibility refers to the responsibility that an individual has for their own actions and decisions.

Social responsibility refers to the responsibility that an individual or organization has to act in the best interest of society.

Professional responsibility refers to the responsibility that individuals have to perform their job duties to the best of their ability.

Answer:

The reaction is at equilibrium.

Explanation:

In thermodynamics, the Gibbs free energy is a term used traditionally to refer to the available or  useful work that can be obtained from a thermodynamic system.

Gibbs free energy is a measure of the chemical potential that a reaction has left to do work. Hence, if the free energy is zero, then the reaction has attained equilibrium, and there is no more work to be done

The statement that should be true related to the reaction should be that it should be at equilibrium.

In terms of thermodynamics, this energy should be applied for the availability or the useful work that should be obtained via the system of thermodynamics.

Also, it determined the chemical potential where the reaction has left for doing the work. Also in the case when the free energy should be zero so here the reaction should be attained the equilibrium.

hence, the option b is correct.

5 Electrons.

Explanation:

Hello.

In this case, an element in group 15 such as nitrogen has 5 electrons on the outer shell because of its electron configuration. For N, whose atomic number is 7, the electron configuration is:

[tex]N^7: 1s^2,2s^2,2p^3[/tex]

Whereas energy level 2 has 5 electrons (2 from 2s and 3 from 2p). Next element is phosphorous and its electrons configuration is:

Because the sugar flour and eggs can no longer be separated. The properties of the materials have changed so it's a chemical change

Sugar, flour, and eggs cannot be separated. The materials' properties have changed, resulting in a chemical change.Therefore, crumbling a cookie is not a physical change.

Physical changes affect a chemical substance's form but not its chemical composition. Physical changes can be used to separate mixtures into their component compounds, but not to separate compounds into chemical elements or simpler compounds.

A chemical change is the transformation of one material into another, the formation of new materials with different properties, and the formation of one or more new substances. It occurs when one substance reacts with another to form a new substance.

A physical change is characterized by a change in physical properties. Melting, transition to a gas, change in strength, change in durability, changes in crystal form, textural change, shape, size, colour, volume, and density are all examples of physical properties.

Thus, crumbling a cookie is not a physical change.

Answer:

(i) Final pressure and temperature are 25.119 bar and 753.566 K, (ii) Final pressure and temperature are 66.289 bar and 994.336 K.

Explanation:

This system experiments an adiabatic compression, as such compression happens with no heat interaction between the piston-cylinder device and surroundings. This is a particular case of polytropic process, in which there is no entropy generation according to the Second Law of Thermodynamics.

The compression process is represented by the following formulas:

[tex]\frac{p_{2}}{p_{1}} = \left(\frac{V_{1}}{V_{2}} \right) ^{\gamma}[/tex] (Eq. 1)

[tex]\frac{T_{2}}{T_{1}} = \left(\frac{V_{1}}{V_{2}} \right)^{\gamma - 1}[/tex] (Eq. 2)

Where:

[tex]p_{1}[/tex], [tex]p_{2}[/tex] - Initial and final pressures, measured in bar.

[tex]T_{1}[/tex], [tex]T_{2}[/tex] - Initial and final temperatures, measured in Kelvins.

[tex]V_{1}[/tex], [tex]V_{2}[/tex] - Initial and final volumes, measured in cubic meters.

[tex]\gamma[/tex] - Specific heat ratio of air, dimensionless.

From Theory of Diesel and Otto Cycles we know that compression ratio is defined as:

[tex]r_{c} = \frac{V_{1}}{V_{2}}[/tex] (Eq. 3)

And (Eqs. 1, 2) can be rewritten as follows:

[tex]\frac{p_{2}}{p_{1}} = r_{c}^{\gamma}[/tex] (Eq. 1b)

[tex]\frac{T_{2}}{T_{1}} = r_{c}^{\gamma - 1}[/tex] (Eq. 2b)

Then, we clear final pressure and pressure in each expression and calculate them for each case:

[tex]p_{2} = p_{1}\cdot r_{c}^{\gamma}[/tex]

[tex]T_{2} = T_{1}\cdot r_{c}^{\gamma-1}[/tex]

(i) [tex]r_{c} = 10[/tex], [tex]p_{1} = 1\,bar[/tex], [tex]T_{1} = 300\,K[/tex], [tex]\gamma = 1.4[/tex]

[tex]p_{2} = (1\,bar)\cdot 10^{1.4}[/tex]

[tex]p_{2} = 25.119\,bar[/tex]

[tex]T_{2} = (300\,K)\cdot 10^{0.4}[/tex]

[tex]T_{2} = 753.566\,K[/tex]

Final pressure and temperature are 25.119 bar and 753.566 K.

(ii) [tex]r_{c} = 20[/tex], [tex]p_{1} = 1\,bar[/tex], [tex]T_{1} = 300\,K[/tex], [tex]\gamma = 1.4[/tex]

[tex]p_{2} = (1\,bar)\cdot 20^{1.4}[/tex]

[tex]p_{2} = 66.289\,bar[/tex]

[tex]T_{2} = (300\,K)\cdot 20^{0.4}[/tex]

[tex]T_{2} = 994.336\,K[/tex]

Final pressure and temperature are 66.289 bar and 994.336 K.

Answer:

Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. ... If that velocity is zero, then the object remains at rest.

Explanation:

Answer:

Before Galileo and Newton, many people thought that objects lost speed because they had a built-in natural tendency to do so. But those people weren't taking into account the multiple forces here on Earth - for example, friction, gravity, and air resistance - that cause objects to change their speed. If we could see the motion of an object in deep interstellar space, we would be able to observe the natural tendencies of an object that is free from any external influence. In deep interstellar space we would observe that if an object had a speed, it would continue to move with that speed until there was some force causing a change in its motion. Likewise, if an object were at rest in interstellar space, it would remain at rest until there was a force causing a change in its motion.

Argon

Explanation:

The element that would most likely be a good substitute for neon is "argon".

These two elements belong to the noble gases in Group 18(8A) of the Periodic Table. They are inert gases - they do not react chemically with other substances.

Argon, as an inert gas is often used whenever an inert atmosphere is needed. Argon is used in incandescent light bulbs. It is used to stop oxygen from corroding the filament. It is also used by welders to protect weld area.

Argon is a good substitute for neon in this context because they possess some physical properties which are similar.
