Answer: The electron configuration of nitrogen (N) is 1s22s22p3.

Explanation:

When electrons of an atom are distributed in a molecular orbital then this distribution is known as electronic configuration.

Atomic number of nitrogen is 7 and its electronic distribution is 2, 5.

Whereas the electronic configuration of nitrogen is as follows.

$1s^{2}2s^{2}2p^{3}$

Thus, we can conclude that out of the given options only option (A) depicts correct electron configuration of nitrogen (N).

In this reaction, what roll does the lead (II) nitrate play when 50.0 mL of 0.100M iron (III) chloride are mixed with 50.0 mL of

Aloiza [94]

Answer: The roll of lead (II) nitrate is that it is a limiting reactant of the reaction.

Solution : Given,

Molarity of $FeCl_3$ = 0.1 M

Volume of $FeCl_3$ = 50.0 ml = 0.05 L (1 L = 1000 ml)

Molarity of $Pb(NO_3)_2$ = 0.1 M

Volume of $Pb(NO_3)_2$ = 50.0 ml = 0.05 L

First we have to calculate the moles of $FeCl_3$ and $Pb(NO_3)_2$ .

$\text{ Moles of }FeCl_3=\text{ Molarity}\times \text{ Volume in L}$

$\text{ Moles of }FeCl_3=(0.100M)\times (0.05L)=0.005moles$

$\text{ Moles of }Pb(NO_3)_2=\text{ Molarity}\times \text{ Volume in L}$

$\text{ Moles of }Pb(NO_3)_2=(0.100M)\times (0.05L)=0.005moles$

The balanced chemical reaction is,

$2FeCl_3+3Pb(NO_3)_2\rightarrow 2Fe(NO_3)_3+3PbCl_2$

From the balanced chemical equation, we conclude that

3 moles of lead nitrate react with 2 moles of ferric chloride.

Thus 0.005 moles of lead nitrate react with $=\frac{2}{3}\times 0.005=0.0033$ moles of ferric chloride.

Moles of ferric chloride will be left unreacted = 0.005 - 0.0033 =0.0017 moles

Limiting reagent is the reagent in the reaction which limits the formation of product.

Excess reagent is the reagent in the reaction which is in excess and thus remains unreacted.

Therefore, in the given reaction, lead nitrate is the limiting reagent and ferric chloride is the excess reagent.

Which of the following statements is true about aquaculture? A. An aquaculturist can throw some young shrimp in a pond, and they

Delvig [45]

B. Aquaculture means "cultivating small acreages of land."

Explanation:

Aquaculture is the growing of fishes, crustaceans, molluscs, oysters and other marine organisms like algae in a small acreage of farm. Normally, the carryign capacity per acreage would be lower in the natural habitat – like in the oceans- but this is raised substantially in aquaculture due to adopting certain farming techniques. An example is by cycling the wastewater from teh fish tanks to plants that take up the waste as nutrients and oxygenate the water, The water is then recycled back to the tanks as cleaner water reusable by the fishes and teh cycle continues. This cycle ensures the sustainability of the farm even with very little water compared to the natural environment.

Organic compounds are composed of __________ and at least one hydrogen atom.

Anettt [7]

I think the correct word to fill in the blank would be carbon. Organic compounds are composed of carbon and at least one hydrogen atom. It is basically any compound that would contain carbon and covalently bonded to other elements or atoms usually these are hydrogen, nitrogen and oxygen. All living things are based on these compounds. These are the building blocks of organic chemistry. These compounds can be seen anywhere in Earth. May it be animals, plants, the soil, sugar, microorganisms and even in humans. Examples of these compounds are methanol, DNA, glucose, hexane, acetic acid, butane and the like.
