There are three types of rocks namley sedimentary rocks, metamorphic rocks and igneous rocks. They will interchange to each other by the process called rock cycle.

Rock cycle illustrates how the three primary types of rocks—sedimentary, metamorphic, and igneous—change over the course of geologic time. When a rock is pushed out of its equilibrium circumstances, it changes.

For instance, an igneous rock like basalt may disintegrate and evaporate when exposed to air or melt when it is subducted beneath a continent.

Rocks do not stay in an equilibrium state; rather, they change as they interact with new environments because of the driving forces of the rock cycle, plate tectonics, and the water cycle.

The rock cycle illustrates the relationships between the three types of rocks and the gradual transition of processes from one type to another.

Luminol is a chemical compound with a heterocyclic structure. It is used as a reagent in the identification of bloodstains and is important in forensic chemistry.

Luminol tautomerizes from its neutral form to its zwitterionic form in a base-catalyzed reaction that produces light. A base-catalyzed mechanism that shows the tautomerization of neutral luminol to its zwitterionic form using ChemDraw is given below:In the initial step, the lone pair of electrons on the nitrogen atom in the luminol molecule interacts with the hydrogen ion provided by the base, resulting in the formation of an intermediate compound with a positive formal charge on the nitrogen atom.

Next, the nitrogen atom donates its lone pair of electrons to the carbonyl carbon atom, forming a double bond and a negatively charged intermediate species. Subsequently, the negative charge is delocalized via resonance, forming a stabilized intermediate product. Finally, the proton is transferred from the oxygen atom to the nitrogen atom, resulting in the formation of the zwitterionic form of luminol. The above-given mechanism shows that the base-catalyzed tautomerization of luminol to its zwitterionic form proceeds via several steps, involving the formation of intermediate products with formal charges on them.

A formula for the sensitivity dR/dM  represents the sensitivity of the body's reaction to the medication. It shows how the reaction changes with respect to the dose of the medication, M. The term M*C represents the contribution of the constant C to the sensitivity, while the term \((2M^2)/3\) represents the contribution of the dose M itself.

To find a formula for the sensitivity, dR/dM, let's differentiate the given function R(M) with respect to M.

Step 1: Start with the function \(R(M) = M^2(C/2 - M/3).\)

Step 2: Apply the power rule of differentiation to differentiate M^2. The power rule states that if

\(f(x) = x^n, then f'(x) = n*x^(n-1). \\\)

n this case, n = 2.

\(dR/dM = 2M^(2-1)*(C/2 - M/3).\)

Simplifying, we have:

\(dR/dM = 2M*(C/2 - M/3).\)

Step 3: Distribute the 2M to each term inside the parentheses:

\(dR/dM = M*C - (2M^2)/3.\)

This formula represents the sensitivity of the body's reaction to the medication, dR/dM. It shows how the reaction changes with respect to the dose of the medication, M. The term M*C represents the contribution of the constant C to the sensitivity, while the term \((2M^2)/3\) represents the contribution of the dose M itself.

the formula for the sensitivity, or the rate of change of the reaction R with respect to the dose M, is

dR/dM = MC - M\(^2^/^3\)

We calculate the derivative of the reaction function R(M) with respect to M.

the reaction function: R(M) = M²(C/2 - M/3)

We will apply  the power rule and the constant multiple rule of differentiation,

dR/dM = d/dM [M²(C/2 - M/3)]

= 2M(C/2 - M/3) + M²(0 - (-1/3))

= 2M(C/2 - M/3) + M\(^2^/^3\)

dR/dM =\(MC - 2M^2^/^3 + M^2^/^3\)

Answer:

Large amount of gas can be stored in small container.

Explanation:

They are compressed so that a larger amount of gas can be stored in a smaller container. A greater mass confined to a smaller volume makes transporting and storing of gases easier. Increasing temperature increases pressure, and the cylinders might explode.

Let's call the volume of the 50% alcohol mixture used x and the volume of the 85% alcohol mixture used y. We know that the total volume of the solution must be 455 ml, so:

x + y = 455 ml

To find the amount of alcohol in each mixture, we need to multiply the volume of each mixture by its concentration.

For the 50% alcohol mixture:

0.50 * x = 0.80 * (x + y) * 0.5 -------(1)

And for the 85% alcohol mixture:

0.85 * y = 0.80 * (x + y) * 0.55 -----(2)

We can substitute the second (2) into the (1):

0.50 * x = 0.80 * (x + y) * 0.5

0.50 * x = 0.80 * (x + y) * 0.5

0.50 * x = 0.44 * (x + y)

Finally, we can solve for x and y by dividing both sides of the equation by 0.44:

x = (0.50 * x) / 0.44

x = (0.50 * x) / 0.44

x = 227.27 ml

And then, we can find y by using the  equation (1):

y = 455 ml - x

y = 455 ml - 227.27 ml

y = 227.73 ml

So, we need 227.27 ml of the 50% alcohol mixture and 227.73 ml of the 85% alcohol mixture to obtain the desired 80% alcohol solution.

Answer:

T₂ = 182 K

Explanation:

Given that,

Initial pressure, P₁ = 120 kPa  

Initial temperature, T₁ = 0˚C = 273 K

We need to find the final temperature when the pressure is 80 kPa.

We know that, Gay Lussac's Formula is :

\(\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}\\\\T_2=\dfrac{P_2T_1}{P_1}\\\\T_2=\dfrac{80\ kPa\times 273}{120\ kPa}\\\\T_2=182\ K\)

So, the new temperature is equal to 182 K.
