The student is now told that the four solids, in no particular order, are magnesium bromide (MgBr2), sugar (C6H12O6), butanoic a

cid (C3H7COOH), and potassium bromide (KBr). Assuming that conductivity is correlated to the number of ions in solution, rank the four substances based on how well a 0.20 M solution in water will conduct electricity.

Answer:

Magnesium chloride (MgCl₂) > Potassium bromide (KBr) > Butanoic acid (C₃H₇COOH) > Sugar (C₆H₁₂O₆)  (Conductivity)

Explanation:

The given samples:

<u>Magnesium chloride (MgCl₂):</u>

It is a strong salt which dissociates 100% into 3 ions, 1 Mg²⁺ and 2 Cl⁻

<u>Sugar (C₆H₁₂O₆):</u>

It is a carbohydrate and will have 0% dissociation and thus, no ions.

<u>Butanoic acid (C₃H₇COOH):</u>

It is a carboxylic acid (weak acids) which partially dissociates.

<u>Potassium bromide (KBr):</u>

It is a strong salt which dissociates 100% into 2 ions, K⁺ and Br⁻.

Thus, Conductivity is directly proportional to the numbers of ions dissociated in the solution and hence will conduct more electricity.

So,

<u>Magnesium chloride (MgCl₂) > Potassium bromide (KBr) > Butanoic acid (C₃H₇COOH) > Sugar (C₆H₁₂O₆)  (Conductivity)</u>

tiny-mole [99]

Answer:

Check the explanation

Explanation:

When talking about our universe there are 5 d orbitals. The element of first transition series moves away from the universal principles of Hund's rule and Aufbav's principle. So in order to attain stability these elements tend to form half or full filled orbitals.

In our universe the ground state electronic configuration of sixth transition metal, Iron (Fe) :  [Ar] 3d^{6} 4s^{2}

and the electronic configuration of seventh transition metal, Cobalt (Co) :  [Ar] 3d^{7} 4s^{2}

=================================

=================================

In universe L there are seven orbitals.

Ground state electronic configuration of sixth and seven transition element.

Sixth transition metal: [Ar] 3d^{7} 4s^1 or [X] 3d^{7} 4s^1

Seventh transition metal: [Ar] 3d^{7} 4s^{2}or [X] 3d^{7} 4s^{2}
