The continuation of the electronic configuration would be [tex]3p^6, 4s^6, 3d^4.[/tex]

Electronic configuration, also called electronic structure, is the arrangement of electrons in energy levels around an atomic nucleus.

The initial p-orbital (the [tex]3p^3[/tex]) is incompletely filled. Thus, the first thing would be to fill it completely ([tex]3p^6[/tex]) so as to obey the orbital-filling rule. This leaves 6 more electrons.

After 3p orbital, the next orbitals are 4s, 3d, 4p, 5s, etc.

The 4s orbital will take a maximum of 2 electrons, leaving 4 more electrons.

Next would be the 3d orbital which can take a maximum of 8 electrons, but only 4 electrons are left.

Thus, the electronic configuration would be [tex]3p^6, 4s^6, 3d^4.[/tex]and elements is Vanadium (V).

Answer:

Alkaline batteries stop working when all of the manganese dioxide has been converted.

Explanation: Hope it helps you :)))

Have a good day

Alkaline batteries eventually stop working because the chemicals inside them react and eventually use up all their energy.

The chemicals in an alkaline battery are zinc and manganese dioxide, which are separated by a separator. When the battery is used, zinc and manganese dioxide react to produce electricity.

The reaction between zinc and manganese dioxide is a one-way reaction, meaning that it cannot be reversed. This means that once the chemicals in the battery are used up, the battery will no longer produce electricity.

The rate at which an alkaline battery loses its charge depends on a number of factors, including the temperature, the amount of current being drawn from the battery, and the age of the battery.

In general, alkaline batteries will last longer in cool temperatures and when they are not being used heavily.

Answer: 2 moles

Explanation:

We know from the equation that for every 3 moles of HCl consumed, 2 moles of water are consumed (based on the coefficients)

So, the answer is 2 moles.

Answer:

The solution has a pH value of 9.3.

Explanation:

To solve this problem, we can first determine the H+ ion concentration and then use this value to calculate the pH. To find the H+ ion concentration from the OH- ion concentration, we should use Kw, which we know has a value of 1 * 10^(-14).

We can then use the following formula to solve for [H+]:

Kw = [H+][OH-]

10^(-14) = (2.02 * 10^(-5)) * [H+]

[H+] = 4.950495 * 10^(-10)

Now, we can find the pH using the formula pH = -log[H+].

pH = - log[H+]

pH = - log(4.950495 * 10^(-10))

pH = 9.3

Therefore, the correct answer is that the pH of the solution is 9.3. Note that an alternative way to solve the problem is to find the pOH from the OH- ion concentration and use the resulting value to determine the pH that way instead.

Hope this helps!

The new pressure of the gas would be 994 mmHg

According to Charle's law, the pressure of a gas at a constant temperature varies inversely with its volume.

Mathematically: p1v1 = p2v2, where p1 and p2 = initial and final pressure, and v1 and v2 = initial and final volume.

In this case, v1 = 14.5 L, p1 = 720 mmHg, and v2 = 10.5 L

p2 = p1v1/v2 = 720 x 14.5/10.5 = 994 mmHg

146 neutrons

Explanation:

The atomic number of uranium (see periodic table) is 92, and the mass number of the isotope is given as 238. Therefore, it has 92 protons, 92 electrons, and 238 — 92 : 146 neutrons.

More positive ions shows acidic whereas more negative ions indicates basic solution.

That side which has more positive charges is considered as acidic solution while on the other hand, that region where negative charges are present in large number as compared to positive charges is considered as basic or alkaline solution.

So we can conclude that more positive ions shows acidic whereas more negative ions indicates basic solution.

Answer:Amplitude:the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path.Wave speed:Wave speed is the distance a wave travels in a given amount of time, such as the number of meters it travels per second. Wave speed is related to wavelength and wave frequency by the equation: Speed = Wavelength x Frequency. This equation can be used to calculate wave speed when wavelength and frequency are known.Wavelength:Wavelength is the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire. In wireless systems, this length is usually specified in meters (m), centimeters (cm) or millimeters (mm).Frequency:frequency, in physics, the number of waves that pass a fixed point in unit time; also, the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.

Answer:

There are 72grams in 4 moles of H20

Answer:B

Explanation:got it right

The statement, "It is technically challenging to create nuclear fusion reactions safely and efficiently", is related to nuclear fusion reaction. Thus, Option B is correct.

This is due to the need to reach and maintain the extreme temperatures and pressures required for the reaction to occur and to confine and control the plasma in which the reaction takes place.

Nuclear fusion is a promising source of energy that has the potential to provide abundant, clean & sustainable power. However achieving nuclear fusion requires overcoming several challenges including the technical difficulties of creating and controlling the extreme conditions required for the reaction to occur.

Fusion reactions can produce high-energy neutrons that can damage the materials used to contain the reaction and require special handling and disposal. While progress has been made in developing fusion technologies, there is still much work to be done to make fusion a viable source of energy for the future.

When comparing voltaic and electrolytic cells oxidation occurs at both the anode and the cathode.

In an electrolytic cell, the reaction is non-spontaneous so it requires some input of energy for it to function while for a voltaic cell, the reaction is spontaneous.

Oxidation occurs at the anode and reduction occurs at the cathode.

Thus, when comparing voltaic and electrolytic cells oxidation occurs at both the anode and the cathode.
