The complex ion [CoBr6]3− is a high-spin complex and absorbs light at a wavelength greater than 7.70×102 nm . How many unpaired

electrons will be present in the complex?
Mathematics
1 answer:
NeX [460]3 years ago
3 0

Answer:

4 electrons

Step-by-step explanation:

[CoBr₆]³⁻ contains Cobalt as the central metal ion and 6 bromide atoms are bonded to the metal as ligands.

Bromide is a weak field ligand and thus pairing of the electrons will not take place and the complex, [CoBr₆]³⁻ is a high spin complex.

The oxidation number of Co in [CoBr₆]³⁻ is +3.

The Electronic configuration of Co³⁺ in [CoBr₆]³⁻ (d⁶) in a weak field octahedral environment is t_{2g}^4 e_g^2

<u>Number of unpaired electrons = 4 electrons</u>

Six Less than the product of 4 and a number is equal to 5. Write an equation
Anna71 [15]
Let "x" be the mystery number
A product of 4 and this number = 4x
Six less that that = subtracting six from 4x
So the final equation is
4x-6=5

P.S.: x = 2.75

On a soccer team 40% of the goal are scored by a star player on the team.If 70 goals were scored all season, how many are scored
VMariaS [17]

Answer:

42

Step-by-step explanation:

During the season, 40% of the goals are scored the by the star player.  This means that 60% of the goals are scored by everyone else.

100% - 40% = 60%

To find how many goals are scored by the rest of the team, convert the percentage to a decimal.  You then have to multiply the decimal by the total goals scored.

60% = 0.6

70 × 0.6 = 42

The rest of the team scored 42 goals.

Solve for (x,y,z)<br> x = 6z + 13 -4x <br> - 6y - 4z = 32 <br> 6x + y - 7z = -9
Aliun [14]

1. x=6z+13/5

2. y= -2z-16/3

3. z= 6x/7+y/7+9/7

Explanations

1 Add 4x to both sides

5x=6z+13

Divide 5 by both sides

x=6z+13/5

2 Add 4z to both sides

-6y=32+4z

Divide 6 by both sides

-6y/-6 = 32/-6 + 4z/-6

Simplify

y=-2(z+8)/3 of y= -2z-16/3

3. Subtract 6x+y from both sides

-7z=-9-6x-y

Divide 7 by both sides

-7z/-7 = -9/-7 - 6x/-7 -y/-7

Simplify

z=6x/7+y/7+9/7

The linear model P = 3.75g + 1.5 predicts the total cost , P, in dollars, to purchase g gallons of gas at a gas station.Based on
Orlov [11]

Answer:

It would cost $46.50 to buy 12 gallons of gas.

Step-by-step explanation:

1. Replace the variables in P = 3.75g + 1.5 with the values you know:

P = 3.75g + 1.5, \text{ where } g =12\\P=3.75(12)+1.5

2. Solve for P:

P=3.75(12)+1.5\\P=45+1.5\\P=46.5
