Which choice best describes the movement of air at Earth's surface during a high-pressure system?
A convergence, sinking air
B divergence, sinking air
C divergence, rising air
D convergence, rising air
The answer your looking for is most certainly B cause as a result Divergence sinking air high pressure and mixed with sinking air it produces high pressure for example when hot and cold air mix it makes a Tornado so B is your most selected option! UwU lol
The choice that best describes the movement of air at Earth's surface during a high-pressure system is divergence, sinking air. The correct option is B.
What is divergence and sinking air?Divergence is one of the processes of movements of plates of the earth. There are three processes by which the plates move. Divergence is the one where the two plates move toward each other.
Sinking air increase the pressure at the surface. They create high-pressure belts in the latitudes. When the air moves away from the poles, the pressure starts to decrease.
So, the remaining are convergence and rising air, they both create low-pressure belts. As we move upwards, the pressure decrease due to gravitational force.
Thus, the correct option is B. divergence, sinking air.

The second-order rate constant for the following gas-phase reaction is 0.048 1/MLaTeX: \cdot⋅s. We start with 0.1 mol C2F4 in a 2.31 liter container, with no C4F8 initially present. C2F4 LaTeX: \longrightarrow⟶ 1/2 C4F8 What will be the concentration of C4F8 after 2.1 hours?
Answer:
[tex][A]=0.0026M[/tex]
Explanation:
Hello.
In this case, since the second-order rate law is:
[tex]\frac{dC_A}{dt}=-kC_A^2[/tex]
Whereas the subscript A accounts for C2F4 and its integration turns out into:
[tex]\frac{1}{[A]}= \frac{1}{[A_0]} +kt[/tex]
Thus, for the initial concentration of C2F4 computed via the 0.1 mol in the 2.31-L container:
[tex][A]_0=\frac{0.1mol}{2.31L} =0.043M[/tex]
The final concentration after 2.1 h is:
[tex]\frac{1}{[A]}= \frac{1}{0.043M} +\frac{0.048}{M*s} *\frac{3600s}{1h}*2.1h\\\\\frac{1}{[A]}=\frac{386.1}{M}[/tex]
Solving for the final concentration of C2F4, we obtain:
[tex][A]=\frac{M}{386.1} =0.0026M[/tex]

If 1.48 g of Cl2 reacts with excess P, what is the total change in enthalpy in kilojoules? 2P+5Cl2⟶2PCl5ΔH=−886kJ
Answer:
-3.72 (or -3.70 depending on what values you used)
Explanation:
First, use the molar mass of Cl2 convert the mass of Cl2 to moles.
1.48 g Cl2(1 mol70.906 g)=0.02087 mol Cl2
Note that we are given ΔH=−886kJ. This refers to the enthalpy change associated with the reaction of 5mol of Cl2 by the balanced equation shown below.
2P+5Cl2⟶2PCl5ΔH=−886kJ
Therefore, to determine the enthalpy change associated with the reaction of 1.48gCl2, divide ΔH by 5molCl2 to determine the enthalpy change per mole of Cl2, then multiply by 0.02087 mol Cl2. (note: if you round up here to .021 mol of Cl2 you will get the final answer of -3.72 later)
0.02087 mol Cl2(−886 kJ5 mol Cl2)=−3.698 kJ
Rounding the answer should to three significant figures, we find that the enthalpy change associated with the reaction of 1.48gCl2 is −3.70 kJ.
Notice that coefficients in stoichiometric equations (indicating numbers of moles) are exact, so they do not constrain the number of significant figures.
The enthalpy change for the reaction when 1.48 g of Cl₂ reacts with excess P is –3.69 KJ.
We'll begin by calculating the number of mole of in 1.48 g of Cl₂. This can be obtained as follow:
Molar mass of Cl₂ = 2 × 35.5 = 71 g/mol
Mass of Cl₂ = 1.48 g
Mole of Cl₂ =?Mole = mass / molar mass
Mole of Cl₂ = 1.48 / 71
Mole of Cl₂ = 0.0208 moleFinally, we shall determine the enthalpy change for the reaction. This can be obtained as follow:
2P + 5Cl₂ —> 2PCl₂ ΔH = −886 KJ
From the balanced equation above,
5 moles of Cl₂ reacted to produce an enthalpy change of −886 KJ.
Therefore,
0.0208 mole of Cl₂ will react to produce an enthalpy change of = [tex]\frac{0.0208 * - 886}{5}\\\\[/tex] = –3.69 KJ.
Thus, the enthalpy change for the reaction when 1.48 g of Cl₂ reacts with excess P is –3.69 KJ.

What is the double displacement reaction?The double displacement reaction is the reaction in which two reactants create two new compounds by exchanging ions. Precipitates are frequently formed as a byproduct of double displacement processes. One element from the solution and another elements form a precipitate.
According to rules of solubility, the sulfides are usually not soluble in water and sodium nitrate is readily soluble in water, so it is clear that the precipitate is formed by the sulfide group. The solution will be formed by sodium nitrate.
Thus, the correct option is D. (NH4)2S.

A substance has a sea level boiling point of 78°C. You take the substance about 3,000 meters up a mountain and heat it in a pot. What would be the most likely boiling point for this substance at that elevation: 68°C, 78°C, 95°C, or 100°C? Explain.
Answer:
68 °C.
Explanation:
Hello.
In this case, since the relationship between the altitude and the boiling point is inversely proportional due to fact that the higher the altitude the lower the atmospheric pressure and therefore the lower the boiling point (temperature) and the lower the altitude the higher the atmospheric pressure and therefore the higher the boiling point. This is supported by the fact that at lower atmospheric pressures, more liquid molecules are likely to become gas since a weaker force is holding them together in liquid state and the other way around.
Therefore, the most likely boiling point at 3,000 m up a mountain will be below 78 °C, it means 68 °C.
Best regards.
The most likely boiling point for this substance at an elevation of 3,000 meters up a mountain is: A. 68°C.
Given the following data:
Boiling point at sea level = 78°CAltitude = 3,000 metersTo determine the most likely boiling point for this substance at that elevation:
Boiling point can be defined as the temperature at which a physical matter changes phase or state, especially from liquid to gas.
The boiling point of a substance is inversely proportional to altitude due to the effect of atmospheric pressure.
This ultimately implies that, the higher the altitude, the lower the boiling point and the lower the altitude, the higher the boiling point.
In this context, the boiling point of a substance at higher altitude such as on a mountain is lower because there is less atmospheric pressure acting on its molecules.
Deductively, the most likely boiling point for this substance at an elevation of 3,000 meters up a mountain would be less than 78°C.
