Although you have not provided the circled electron, I can help you with a wide explanation.

1) Atomic number of manganese is 25. That means that it has 25 protons and 25 electrons.

2) Those 25 electrons are distributed (electron configuration) as per the quantum rules:

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁵

3) The most reasonable is that you have been asked to give the possible quantum numbers for an electron in the 4s or 3d.

4) Those are 7 electrons and these are their possible sets of quantum numbers:
i) For the two electrons in 4s: 
n is the main energy level so n = 4
l tells the kind of orbital, which is s, so l = 0
ml is also 0 (it can be from -l to + l, so given that l i s0, ml is 0)
ms: one is +/12 and the other is -1/2 (this is the spin number).


ii) For the 5 electrons in 3d

n = 3
l can be 0, 1, or 2
if l = 0, then ml = 0

if l = 1, then ml can be -1, 0 , or 1 (from - l to + l)


ms can be either +1/2 or - 1/2 (spin)

A nonplar solvent would most easily dissolve which of the following substances?
Alika [10]

Answer:

Nonpolar Solvent. Carbon tetrachloride. CCl4

Explanation:

The other compounds listed are polar;

polar substances are by their nature more soluble in Other polar compounds. NH3 is a gas; so unless it was a very specific compound you needed in ammonia gas, it, being also polar as well as a gas would not be a good choice for this question.

The movement of salt molecules in a system and surroundings that have different concentrations follow the osmosis principle. Osmosis is the phenomena where molecules move from lower concentration to higher concentration through a sem-permeable membrane. when the concentration is higher outside, then answer is C. molecules <span>move out of the cell, and the cell will shrink or shrivel.</span>

Limonene is one of the compounds that give lemons their tangy odor. Show the structures of the products expected when limonene r
iVinArrow [24]

Answer:

Explanation:

The alkene reactions in general are addition or oxidation reactions. For the addition reaction, we have to take into account that some of them are marknonikov and other anti-markovnikov. Also for the addition reaction, we will have to take into account if we will have anti or syn products. In the oxidation reaction, we have to know the specifics for each reaction. If the reaction can go to the highest oxidation level, is the double bond is broken, etc.

Each reaction has its <u>specific characteristics</u> (see figures 1 and 2).

PbO2 + 4HCl --- PbCl2 + Cl2 + 2H2O who buys electrons and who loses electrons?​
SIZIF [17.4K]

<u>Answer:</u> Electrons are taken up by PbO_2 and they are lost by HCl

<u>Explanation:</u>

Redox reaction is defined as the reaction in which oxidation and reduction take place simultaneously. It is also called the reaction where the exchange of electrons takes place.

An oxidation reaction is defined as the reaction in which a chemical species loses electrons takes place. In this reaction, the oxidation state of a substance gets increased.

A reduction reaction is defined as the reaction in which a chemical species gains electrons takes place. In this reaction, the oxidation state of a substance gets reduced.

For the given chemical reaction:

PbO_2+4HCl\rightarrow PbCl_2+Cl_2+2H_2O

The half-reactions for this redox rection follows:

<u>Oxidation half-reaction:</u>  2HCl\rightarrow ClO_2 + 2e^-

<u>Reduction half-reaction:</u>  PbO_2+2e^-\rightarrow PbCl_2

Hence, electrons are taken up by PbO_2 and they are lost by HCl

A cell has the reaction Co2+ (aq) + Cd(s) -------&gt; Cd2+ (aq) + Co(s) E0cell = +0.120 V What is Ecell when [Co2+] = 0.00100 M
musickatia [10]

Answer:

USe this Nernst equation and find your required answer

Explanation:

E = E0 -  [0.0592 /n ] log [Cd+2]/[Co2+]

Wher Eo is  +0.120 V

[Cd+2] =0.1

[Co2+] = 0.001

n is number of electons transfered int he process and in your case it is = 2

E= 0.120- 0.0296 * log 100

  = ........  V
