Choose the best description of what is wrong with the following electron configuration for an electrically neutral atom of Chlor

ine (Atomic Number 17) 1s2 2s2 2p5 3s2 3p6
Question 2 options:

The total number of electrons in the configurations does not equal 17, the atomic number of chlorine


There are low energy orbitals which have not been filled to hold the maximum number of electrons


The configuration is incorrect for BOTH of these reasons


The configuration is incorrect for NEITHER of these reasons

I believe it is "There are low energy orbitals which have not been filled to hold the maximum number of electrons" because it went from 2p5 to 3s2 and it was supposed to go from 2p6 to 3s2. 

I hope this helps

Draw the structure with the molecular formula C6H14O that most likely produced the below IR and 1H NMR. The 13C NMR data is 78.3
spayn [35]

Answer:

                   The answer is 2,3-dimethylbutan-2-ol and the structure is attached below.

Explanation:

                     Although we are not provided with ¹H-NMR spectrum and IR spectrum but still we can elucidate the ¹³C-NMR data and finalize a plausible structure.

                      First of all we look at the molecular formula, we can conclude from the formula that the structure given is saturated in nature because the hydrogen deficiency index of this formula is zero. Hence, we can say that there is no double bond either between Carbon atoms or between carbon and oxygen atom. This can also be proved by the absence of peaks in downfield as unsaturated compounds and carbonyl compounds give value above 100 and 200 ppm respectively.

                      Secondly, we can also conclude that among the six carbon atom two pairs of them are having same electronic environment because we are having only 4 signals hence we can conclude that two pairs have same chemical shift values.

                       Also, after making every possinble isomer of given molecular formula the structure of 2,3-dimethylbutan-2-ol was found to be the most accurate structure.

Feeding levels within an ecosystem are
alisha [4.7K]

Answer:

C. trophic levels

Explanation:

Trophic levels are the feeding positions of all organisms in a specific ecosystem. There are five main trophic levels, or feeding levels.

-----------

Habitats are the environment in which organisms live. They are not feeding levels.

Taxonomic levels are a way of classifying species. They consist of (in order) domain, kingdom, phylum, class, order, family, genus, and species. They are not feeding levels.

Cladograms are branching diagrams that show the relationship between multiplt organisms/species. It too is not a feeding level.

Thus, is answer is C.

hope this helps!

Why does burning fossil fuels put ecosystems under pressure?
otez555 [7]

Answer:

When fossil fuels are burned, carbon- dioxide and other greenhouse gases are released which trap the Sun's heat and can lead to global warming. The over heating of the atmosphere can put ecosystems under pressure especially the tundra regions.
