For the table that follows, indicate which orbital corresponds to each set of quantum numbers. Ignore x, y, and z subscripts. If the quantum numbers are not allowed (i. e., contain an illegitimate value), indicate that by using the "not allowed" label. Drag the appropriate labels to their respective targets.

1s

not allowed

3d

not allowed

not allowed

4d

5f

Explanation:

Coefficient = n

l = n-1, where 0=s, 1=p, 2=d, 3=f

ml = -l to +l

The quantum numbers are used to show the arrangement of electrons in orbitals in an atom.

There are four sets of quantum numbers;

Now we are going to assign orbitals to each arrangement of quantum numbers as shown below;

n        l         ml          orbital

1         0        0            1s

3        -3        2           not allowed

3        2        -2           3d

2        0        -1           not allowed

0        0        0           not allowed

4        2         1           4d

5        3         0          5f

We can see that s p d f corresponds to l = 0 1 2 3.

Also note that;

When l = 0 then m= 0

When l= 1, m = -1, 0, 1

When l= 2  m = -2, -1, 0, 1, 2

When l =3  m = -3, -2, -1, 0, 1, 2, 3

Note that n must take positive integer values greater than zero.

1. the question asks the most appropriate, which seems to rule out "all of the above." your choice appears to be the correct one.

2. the protocol described is good for identifying correlation, but not cause and effect. for cause/effect, you need to devise a protocol that will assign the treatment (or not) to groups that have essentially the same "demographics" with respect to all the other variables. your choice regarding control group seems appropriate. random assignment of treatment (choice d) may be appropriate also. (i think you can argue that b and d are just different descriptions of the same method.)

3. d will randomize the birds, but may not guarantee there are 10 in each group. e will do both, so seems the better choice.

comment on question 2

based on the problem statement, it seems clear that confident, attentive drivers are more likely to use daytime running lights. so, the protocol might need to be devised in such a way that the lights would be turned on or off without the driver's knowledge. (an attentive driver will figure it out.) assigning a confident, attentive driver to a group required to drive without running lights might mess with his/her confidence and attentiveness. you don't want your experiment to do that. (nor do you want the experiment to subject a driver to greater risk of accident as a consequence of driving without running lights.) experiments involving human safety are always problematic.

the correct answer is:

a. formation of precipitation
