The order of decreasing vapor pressure at a given temperature is CF4 > PF5 > BrF3.
What is Vapor pressure?
This is defined as the pressure exerted by the gas in equilibrium with a solid or liquid in a closed container at a given temperature.
CF4 has very little vapor pressure as a result of its symmetrical structure which is why it has the least vapor pressure.

For the galvanic (voltaic) cell fe(s) + mn²⁺(aq) ⟶ fe²⁺(aq) + mn(s) (e° = 0.77 v at 25°c), what is [fe²⁺] if [mn²⁺] = 0.050 m and e = 0.78 v? assume t is 298 k
The concentration of Iron in the galvanic (voltaic) cell Fe(s) + Mn²⁺(aq) ⟶ Fe²⁺(aq) + Mn(s) is 0.02297 M.
What is the Nernst Equation?The Nernst equation enables us to identify the cell potential(voltage) in presence of non-standard conditions in a galvanic cell. It can be expressed by using the formula:
[tex]\mathbf{E_{cell} = E_o - \dfrac{0.059}{n} \times log \dfrac{[Fe^+]}{[Mn^{2+}]}}[/tex]
where;
n = Number of electrons = 2[tex]\mathbf{E_o}[/tex] = Initial voltage = 0.77 V[tex]\mathbf{E_{cell}}[/tex] = Cell voltage = 0.78 V[tex]\mathbf{[Mn^{2+}]}[/tex] = Manganese concentration = 0.050 MReplacing the values into the above equation, we have:
[tex]\mathbf{0.78 = 0.77 - \dfrac{0.059}{2} \times log \dfrac{[Fe^{2+}]}{[0.050]}}[/tex]
[tex]\mathbf{0.78 -0.77= -0.0296\times log \dfrac{[Fe^{2+}]}{[0.050]}}[/tex]

What x values are not included in the domain of the quotient of two functions
Any x value that makes the denominator equal to 0
Explanation:Rational Functions
The quotient of two functions can be rewritten as a rational function. All rational functions have discontinuities in the domain where the denominator equals 0. For this to make sense, remember that anything divided by 0 is undefined.
Examples
To show this idea, I will use the example [tex]\frac{x^3-2}{x+3}[/tex]. For this rational function or quotient of two functions, the x value -3 is not included in the domain. This is due to the fact that when x=-3, the denominator is equal to 0. Thus, the function is undefined at this value.
Calculate the average change of dissolved oxygen per year in the lake over the course of the study
The average change of dissolved oxygen per year in the lake over the course of the study is; 0.11 mg/L
What is dissolved oxygen?Dissolved oxygen is defined as the amount of oxygen gas that is present dissolved in a given volume of water as a solution.
Dissolved oxygen is very important for aquatic animals as it provides the main source of oxygen required for respiration by these animals.
Due to human activities arising from water pollution and heating of water bodies, the amount of dissolved oxygen in water bodies is on the decrease.
To calculate the average change of dissolved oxygen per year in a particular lake, the formula is;
Average change of dissolved oxygen per year = total change over the years/total number of year
Average change of dissolved oxygen per year = (8.6 mg/L - 3.3 mg/L)/(2014 - 1965) = 0.11 mg/L

Throughout a system or process, a valve is a mechanical component that regulates fluid flow and pressure. By carrying out any of the following tasks, a valve regulates the flow and pressure of system or process fluids: fluid flow that is stopped and started. altering (throttling) the fluid flow's rate.
The flow coefficient (Cv) necessary for the system must be identified as the first step in determining the size of a valve. What is a CV factor? a fully open valve with a 1 pressure drop across it will allow 60°F water to pass through it at a rate of US gallons per minute.
The four heart valves that maintain proper blood flow are the mitral, tricuspid, pulmonary, and aortic valves. With each heartbeat, a leaflet (or flap) on each valve opens and closes.

Somatic motor neurons are responsible for the electrical activity to the muscles that move at our will, in the autonomic system they innervate muscle fibers that we cannot move voluntarily.
What are the functions of the motor neurons in the somatic and autonomic nervous systems?Motor neurons in the somatic nervous system act on the skeletal muscles, so they have a transcendental role in locomotor skills.
On the other hand, motor neurons in the autonomic nervous system are responsible for innervating all those muscle fibers that we cannot move voluntarily; that is, the smooth muscles, for example, the movements of our heart.
