The cloud mist as the number of "dry days” increases and fewer precipitation events contributing to the annual total of cloud mist or the dry days has been increased.​

The main procedure of formation of cyclones is that when hot moist air flows at  the upper surface of the ocean it tries to move in upward direction due to which less amount of air is left at the surface of ocean and hence a lower air pressure is created in this area.

Surrounding air which is at higher air pressure try to push the low pressure air which rises the temperature of low pressure air and again this air moves upward leaving behind less air at the surface of the ocean.

When this high temperature and moist air moves in the upward direction it temperature decreases due to which clouds are formed . This combination of clouds and wind continuously grows and started spinning. When this combination of wind and clouds spin fast,  that time an eye is formed at the center. At this center very low air pressure is there and  air with high pressure flows down into this center.

Therefore, The cloud mist as the number of "dry days” increases and fewer precipitation events contributing to the annual total of cloud mist or the dry days has been increased.​

Chemicals used and/or produced by businesses that, if released, might significantly harm people's health are known as toxic industrial chemicals (tic). The three examples of the tics that are readily available are anhydrous ammonia, hydrogen cyanide, and chlorine.

Chlorine is a material that is used in industries and is found in many items that are used in homes.

Chlorine occasionally manifests as poisonous gas. By applying pressure and chilling, chlorine gas can be transformed into a liquid that can be moved and stored. When liquid chlorine is released, it swiftly transforms into gas that spreads quickly and stays close to the ground.

The strong, unpleasant smell of chlorine gas, which is comparable to that of bleach, can be used to identify it. The pungent stink may give people enough warning that they are exposed.

The chlorine gas seems to be yellow-green in color.

Chlorine is not flammable on its own, but it can react explosively or combine with other chemicals, such as turpentine and ammonia, to form explosive compounds.

In the given condition where the thylakoids are isolated from the chloroplasts to make the pH of the thylakoid space acidic, the isolated thylakoid will form the ATP.

ATP is also referred to as Adenosine Triphosphate and is correctly called as the energy currency of the cell as it is responsible molecule for carrying the energy units in the cell. When the isolated thylakoids are made to transfer in the pH = 8 basic solution, then the acidic lumen of the chloroplast will be having a higher concentration of H⁺ ions. When they are placed in the basic solution then the H⁺ ions will move out because of the occurrence of concentration gradient which is higher in the lumen than the surrounding. The chloroplasts will now bear synthesis of ATP. Therefore, the isolated thylakoid is able to make ATP when the lumen is acidic, and the surroundings are made basic in nature.

Thus, the thylakoid which is isolated will bear the synthesis of ATP.

Most of the space in an atom is empty and a small, dense, positively charged nucleus is present at the center, which contained most of the mass of the atom, with the electrons orbiting the nucleus.

In 1909, Rutherford's alpha scattering experiment. In this experiment a stream of high speed alpha particles is directed at a thin piece of gold foil. During this experiment he observed that some of the particles passed through, some were deflected, and some bounced straight back. From this He concluded the following main points:

⇒ Most of the space in an atom is empty. Due to which some of the particles passed through without any change in their paths.

⇒ Some alpha particles were deflected, and some bounced straight back. This indicated a very small, dense, positively charged nucleus at the center, which contained most of the mass of the atom, with the electrons orbiting the nucleus.

According to the Bohr model, electrons orbit the nucleus at constant energies then the speed of the electron is I = 1.05 mA.

The Bohr model, also known as the Rutherford-Bohr model, was first proposed by Niels Bohr and Ernest Rutherford in 1913 and describes an atomic system with an orbiting system of electrons and a small, dense nucleus that is similar to the Solar System in structure but is attracted by electrostatic forces rather than gravity.

Speed of electron = v = 2.19 × 1[tex]$$0^6[/tex]  m/s

Radius of circular path = [tex]$\gamma[/tex] = 5.29 × 1[tex]0^{11}[/tex] m

The period of electron Pn its orbits is,

T = 2π[tex]\gamma[/tex] / V

To find the current represented by the orbiting electron

I (ΔQ/Δf) = |e|/T = |e|V /2πr

substitute the value in the above equation, we get

[tex]$I=\frac{\left(2.19 \times 10^6\right)\left(1.60 \times 10^{-19}\right)}{2(8.14)\left(5.29 \times 10^{-11}\right)} \\[/tex]

simplifying the equation, we get

I = 1.75 × 10-³  C/s

I = 1.05 mA

Therefore, the speed of the electron is I = 1.05 mA.

High silica content lava flow is thick and viscous and does not flow easily.

Though lava rises upwards toward the surface, it is too thick to pass through the Earth's fissures and crevices. Pressure is increasing as the lava continues to surge upward.

The least dangerous process involved in volcanic eruptions is lava flow. The temperature, silica content, extrusion rate, and slope of the terrain are all factors that affect how far a lava flow travels. A lava flow with a high silica content or one that is chilly will not move very far. Such a flow would be extremely viscous (a high resistance to flow). Low silica content is characteristic of basalt flows like those in Hawaii, OR long-distance flow, and low viscosities.

The air behind a cold front is always cooler than the air in front of it.

The air behind a cold front is much colder and drier than the air in front of it. When a cold front passes the temperature can drop by more than 15 degrees in the first hour. Air masses behind a cold front can be cooler and drier than those in front of the front. When a cold front approaches, precipitation may occur just before or during the passage of the front.

Clear skies cooler temperatures and lower relative humidity behind the front are expected. The answer is the boundary between two different air masses where cold air is retreating and warm air is advancing.

Answer: Question 1.: B. Question 2.: D. Question 3.: C. Question 4.: A.

The value of the equilibrium constant at 627 °C, based on equilibrium pressures, will be 44.1.

First, we write the balanced reaction equation:

2 SO₂(g) + O₂(g) → 2 SO₃ (g)

Based on the reaction equation, the expression for the equilibrium constant (Kp) will look like this:

[tex]K_{p} =\frac{(pSO_{3} )^{2} }{pO_{2}(pSO_{2} )^{2} }[/tex]

pSO₃ - partial pressure of sulfur(VI) oxide

pO₂ - partial pressure of oxygen

pSO₂ - partial pressure of sulfur(IV) oxide

To calculate Kp, we need the equilibrium pressures for all three gasses. We already know the pressure for sulfur(VI) oxide (1.10 atm), but we need to calculate it for oxygen and sulfur(IV) oxide as well.

Because the molar ratio of sulfur(IV) oxide and sulfur(VI) oxide is 1:1, that means that for the formation of 1.10 atm of sulfur(VI) oxide, 1.10 atm of sulfur(IV) oxide was expended, so the equilibrium pressure of SO₂ will be 1.48 atm - 1.10 atm = 0.38 atm.

We apply the same principle for oxygen, but because oxygen:sulfur(VI) oxide ratio is 1:2, only 1.10 atm / 2 = 0.55 atm of oxygen was expended for the formation of sulfur(VI) oxide, leaving us with the oxygen equilibrium pressure of 0.74 atm - 0.55 atm = 0.19 atm.

We plug these values into the expression above:

Kp = (1.10 atm)² / (0.19 atm * (0.38 atm)²) = 44.1

The percent of aluminum (Al) by mass in the given mixture of the two powdered oxides is 29%.

The mass percent formula can be expressed by mass of the each element in one mole of the compound. The mass percentage of each component can be calculated as:

Mass percentage = (Mass of an element 1 mole of the compound)/ (molar mass of compound) × 100

Given, the mass of the mixture of the oxides Al₂O₃ and Fe₂O₃ is equal to 10.0 g.

The mass of the Al₂O₃ recovered = 5.5 g

The number of moles of Al₂O₃ = 5.5/101.96 = 0.054 mol

One mole of Al₂O₃ has two moles of aluminum.

0.054 mol Al₂O₃ will have moles of aluminum = 0.054 × 2 = 0.108

The molar mass of the aluminum (Al) = 26.98g/mol

The mass of 0.108 mol of Al = 0.108 × 26.98 = 2.9 g

The percentage by mass of Al in mixture = (2.9/10) × 100 = 29%
