How are electrons added to orbitals in an electron configuration?

Chemistry
1 answer:
Elenna [48]3 years ago
4 0

Answer:

Electrons are added to atomic orbitals in order from low energy bottom of the graph to high (top of the graph according to the Aufbau principle. Principle energy levels are color coded, while sublevels are grouped together and each circle represents an orbital capable of holding two electrons

Three carbon atoms are linked by single covalent bonds such that they form the shape of a V. All of the unshared electrons form
Nostrana [21]

Answer:

C) 8

Explanation:

Total number of carbon atoms = 3

Number of single bonds = 3

So, each carbon is bonded to the next carbon with the single bond, Number of unshared electrons left with the terminate carbons are 3 and with the intermediate carbon is 2.

Thus, the two terminate carbon have 3 hydrogen each and the intermediate will have 2.

<u>Total - 8</u>

Explain and illustrate the notation for distinguishing between the different p orbitals in a sublevel.
masha68 [24]

Here, the three different notation of the p-orbital in different sub-level have to generate

The value of azimuthal quantum number (l) for -p orbital is 1. We know that the magnetic quantum number m_{l} depends upon the value of l, which are -l to +l.

Thus for p-orbital the possible magnetic quantum numbers are- -1, 0, +1. So there will be three orbitals for p orbitals, which are designated as p_{x}, p_{y} and p_{z} in space.

The three p-orbital can be distinguish by the quantum numbers as-

For 2p orbitals (principal quantum number is 2)

1) n = 2, l = 1, m = -1

2) n = 2, l = 1, m = 0

3) n = 2, l = 1, m = +1

Thus the notation of different p-orbitals in the sub level are determined.

16. The concentration of a solution of potassium hydroxide is determined by titration with nitric
____ [38]

Answer:

M_{base}=0.709M

Explanation:

Hello,

In this case, since the reaction between potassium hydroxide and nitric acid is:

KOH+HNO_3\rightarrow KNO_3+H_2O

We can see a 1:1 mole ratio between the acid and base, therefore, for the titration analysis, we find the following equality at the equivalence point:

n_{acid}=n_{base}

That in terms of molarities and volumes is:

M_{acid}V_{acid}=M_{base}V_{base}

Thus, solving the molarity of the base (KOH), we obtain:

M_{base}=\frac{M_{acid}V_{acid}}{V_{base}} =\frac{0.498M*42.7mL}{30.0mL}\\ \\M_{base}=0.709M

Regards.

This reaction shows the complete combustion of octane, C8H18, a component of gasoline. How many moles of O2 are needed to burn 2
ANTONII [103]
How you're going to answer this question is by doing a mole t - chart first you're going to put 2.40 mol of C8H18 opposite of the mol then you're going to find o2 which 256 on the bottom then multiply across to get the answer.

Hope this help, message me if you need more help
