Answer:

Glycogen

Explanation:

a,b,d are lipidic and glycogen is glucide

Answer:

13.3 L

Explanation:

Step 1: Given data

Step 2: Convert P₁ to atm

We will use the conversion factor 1 atm = 1.01325 bar.

3.36 bar × (1 atm / 1.01325 bar) = 3.32 atm

Step 3: Calculate V₂

We will use the combined gas law.

P₁ × V₁/T₁ = P₂ × V₂/T₂

V₂ = P₁ × V₁ × T₂/T₁ × P₂

V₂ = 3.32 atm × 15.0 L × 350 K/298 K × 4.40 atm

V₂ = 13.3 L

C.Potassium

Explanation:

As we know that Potassium is a mineral also at the same time it is an electrolyte. It helps for muscles work involves the muscles so that the heartbeat and breathing could be controlled.

Now as per the periodic table on an early basis that depends upon the similar properties so the element that should be grouped with the sodium is Potassium

hence, the option c is correct

According to the early periodic table the element that has been grouped together with Na has been Potassium. Thus, option C is correct.

The early periodic table has been consisted of the elements that has been arranged based on the increasing order of the atomic mass. The grouping of the elements has been performed based on the similarities with the elements.

The sodium has been the electrolyte that has been responsible for maintaining the electrolyte balance in the human body. The sodium has been the smaller size element with being highly reactive.

The element that has also been small size with high reactive, and has been able to maintain the body electrolyte balance has been Potassium.

Thus, according to the early periodic table the element that has been grouped together with Na has been Potassium. Thus, option C is correct.

Answer:

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.

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.

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:

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:

[tex]P^{15}:1s^2,2s^2,2p^6,3s^2,3p^3[/tex]

Answer:

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.
