given the standard electrode reduction potentials, which reaction will occur spontaneously?
Answers
The chemical reaction that will occur spontaneously is given by this chemical equation: Mg²⁺ + V²⁺ ----> Mg + V.
What is reduction?Reduction can be defined as a half-reaction through which the number of electrons (oxidation states) that is associated with the atoms of a chemical element are changed i.e reduced or decreased.
Based on the chemical reactions with the standard electrode reduction potentials, the half cell (Cu²⁺) with the higher reduction potential (+0.15) will be reduced while the half cell (V²⁺) with a lower oxidation potential (-1.18) will be oxidized and as such the chemical equation is given by:
Mg²⁺ + V²⁺ ----> Mg + V.

The Gibbs free energy ΔG for the vaporisation of 2-methylbutane, in KJ/mol is 8.24 KJ/mol
Data obtained from the question Enthalpy change (ΔH) = 25. 22 KJ/mol Change in entropy (ΔS) = 84.48 J/Kmol = 84.48 / 1000 = 8.448×10¯² KJ/KmolTemperature (T) = 201 KGibbs free energy (ΔG) =? How to determine the Gibbs free energyThe Gibbs free energy for the reaction can be obtained as follow:
ΔG = ΔH – TΔS
ΔG = 25.22 – (201 × 8.448×10¯²)
ΔG = 25.22 – 169.8048

drag the labels to identify the events in the generation of an action potential in order and correctly name the refractory periods.
Answers
An absolute refractory period occurs during depolarization while the relative refractory period takes place during repolarization.
What is an action potential?An action potential refers to a sudden, quick change in electrical potential (voltage) during the transmission of an impulse (signal) to a receptor, across a cellular membrane.
The order of events in the generation of an action potential include the following:
At -60 mV, graded depolarization transmits an area of excitable membrane to threshold.At +30 mV, voltage-gated sodium channels are opened for sodium ions to move into the cell. As repolarization begins, sodium channels close, voltage-gated potassium channels are opened for potassium ions to move out of the cell. Finally, both sodium and potassium channels return to their normal states as the potassium channels is closed.In conclusion, an absolute refractory period occurs during depolarization while the relative refractory period takes place during repolarization.

ninth fifth fourth secondIn air, a sound wave with a frequency of 196 hz has a wavelength of about 1.76 meters. what is the wavelength of a wave if the frequency is increased to 784 hz?
Answers
The wavelength of the sound wave if the frequency is increased to the given value is 0.44m.
Wavelength
Wavelength is simply the distance over which the shapes of waves are repeated. It is the spatial period of a periodic wave.
It is expressed as;
[tex]\lambda = \frac{v}{f}[/tex]
Where v is velocity and f is frequency.
Given the data in the question;
Frequency of sound wave a; [tex]f_a = 196Hz = 196s^{-1}[/tex]Wavelength of sound wave a; [tex]\lambda _a = 1.76m[/tex]Speed of sound wave; [tex]v =\ ?[/tex]
Frequency of sound wave b; [tex]f_b = 784Hz = 784s^{-1}[/tex]Wavelength of sound wave b; [tex]\lambda _b = ?[/tex]
First, we calculate the velocity of the sound wave in air from sound wave a.
[tex]\lambda = \frac{v}{f}\\ \\1.76m= \frac{v}{196s^{-1}}\\\\v = 1.76m * 196s^{-1}\\\\v = 344.96m/s[/tex]
Now, we determine the wavelength of sound wave b using the velocity of sound wave in air calculated above.
[tex]\lambda = \frac{v}{f}\\ \\\lambda = \frac{344.96m/s}{784s^{-1}}\\\\\lambda = 0.44m[/tex]
Therefore, the wavelength of the sound wave if the frequency is increased to the given value is 0.44m.

There is only one net force acting on the charge at the center of the circle that will only be subjected to a repulsive force from the charge is extant on the negative axis of x.
What is a line charge?A line charge refers to the charge that is allocated along a curve that is one dimensional in nature such as a circle.
In physics experiments, line charges are used in wire chambers. Wire chambers are used for high-energy physics experiments.
In summary, the charges are put at equal distances around the circumference of the circle in the example.
Because the charges at the opposing ends of the circle are similar, they exert an equal-magnitude repelling force in the opposite direction on the charge at the center of the circle, thus balancing out the forces.
This is why there is only one net force acting on the charge at the center of the circle that will only be subjected to a repulsive force from the charge is extant on the negative axis of x.

At its current level of output, a firm’s total revenue is greater than its total variable cost but less than its total cost. if the firm is producing at the point where marginal revenue is equal to marginal cost, what should the firm do to maximize profit in the short run?
Answers
In order to maximize profit in the short run; Company is to continue operating at that output level in the short term, since total revenue will cover all of the firm's variable costs and some of its fixed costs.
How to maximize profit?Every firm in the market operates with the primary aim of making profit, which is different from the government that has a primary aim of creating welfare for the people.

Among all pairs of numbers whose difference is 14 find a pair whose product is as small as possible
Answers
The pair two numbers whose difference is 14 and the product is as small as possible (i.e. -49) are (-7,7)
What are word problems?In mathematical concepts, word problems involve a crucial understanding of the problem and knowing which mathematical method and arithmetic operations are best suited to solving the problem.
If we assume that the smaller number should be = a and the larger number = a + 14.
Thus, their product (X) can be expressed as:
= a(a+14)
= a² + 14a
The smallest possible value implies the minimum value, i.e.
[tex]\mathbf{\dfrac{dX}{da} = 2a + 14}[/tex]
Thus,
2a + 14 = 0
a = - 14/2
