Give the set of four quantum numbers that could represent the last electron added (using the Aufbau principle) to the Cl atom.A)

leva [86]

Answer:

n=3, l=1, ml=1ms=+1/2

Step-by-step explanation:

The electron configuration of chlorine atom is; [Ne] 3s² 3p⁵.

This means that the last electron is found in a 3pz orbital.

We can see that the principal quantum number is 3. The electron is in a p orbital so l=1, the electron must be found in a 3pz orbital hence ml=1. The electron is found alone in that orbital hence s= 1/2.

3. Jorge used 2 packs of pencils in the first 1/3 of the year. At what rate is Jorge using pencils?

ANTONII [103]

Answer:

Jorge is using pencils at a rate of 6 packs a year or a rate of 2 packs every four months.

Step-by-step explanation:

1/3 of a year is four months so that would be 2 packs every four months and if you multiply that by three you’d get 12 month, or one year, and 6 packs of pencils.

Quadrilateral HJKL ~ Quadrilateral MPNQ Which statements must be true

LenKa [72]

Answer:

m∠K =m∠N

HJ/MP=JK/PN

Step-by-step explanation:

The picture of the question in the attached figure

we know that

if two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

so

Verify each statement

case a) we have

m∠K =m∠N

The statement is true

Because, angle K and angle N are corresponding angles, and remember that in similar figures corresponding angles are congruent

case b) we have

HJ≅MP

The statement is false

Segment HJ and segment MP are proportional, not congruent

case c) we have

m∠J≅m∠N

The statement is false

Because angle J and angle N are not corresponding angles

case d) we have

HJ/MP=JK/PN

The statement is true

Because, the ratio of its corresponding sides is proportional

so

$\frac{HJ}{MP}=\frac{JK}{PN}=\frac{KL}{NQ}=\frac{HL}{MQ}$

Solve each system by elimination.

meriva

Answer:

4.)

a. x= -6 y-3

5

b. x= 5 y + 13

4 4

3.)

a. x= -4y + -8

5 5

b. x= 3 y+3

2

Step-by-step explanation:

4.)

a. 5x+6y=-15

Add -6y to both sides.

5x+6y+−6y=−15+−6y

5x=−6y−15

Divide both sides by 5.

5x ÷ 5= -6y-15 ÷5

x= -6 y-3

5

b. 4x - 5y=13

Add 5y to both sides

4x−5y+5y=13+5y

4x=5y+13

Divide both sides by 4

4x÷4= 5y+13÷4

x= 5 y + 13

4 4

5.)

a. (5x+4y=-8)

Add -4y to both sides

5x+4y+−4y=−8+−4y

5x=−4y−8

Divide both sides by 5

5x÷5= -4y-8÷5

x= -4y + -8

5 5

b. 2x - 3y = 6

Add 3y to both sides.

2x−3y+3y=6+3y

2x=3y+6

Divide both sides by 2.

2x÷2= 3y+6÷2

x= 3y+3
