What is the mass percent of aluminum in Al(OH)3 the molar mass of AL = 26.98, H = 1.0079, and O = 16.00
LiRa [457]
Mass percentage = (mass of Al)/(Total mass) * 100
= (26.98) / (26.98 + 3 * (1.0079 + 16)) * 100
= 34.59%

He nitrogen cycle is one of the most important (and complex!) of the biogeochemical cycles. Why is nitrogen important?
gayaneshka [121]

Nitrogen is an essential part of proteins and nucleic acids (DNA).

<h3>Why is nitrogen important?</h3>

All living things require nitrogen. It is a part of proteins, ATP, chlorophyll, DNA, and RNA. Given that it makes up a significant portion of the structures of biomolecules in living organisms, its synthesis and consumption in the biogeochemical cycle are of highest importance. Proteins are made up of amino acids (NH2 group).

The structural development of living species' genetic material (DNA, RNA) also involves nitrogen. It is a part of the nitrogenous bases, which together with other nucleotides create RNA and DNA.

Therefore, a nitrogen deficit can cause major structural issues for such an organism.

<h3>What happens if nitrogen cycle is disrupted?</h3>

A number of undesirable consequences can result from the nitrogen cycle being disrupted. For instance, an abundance of nitrogen in aquatic systems leads to eutrophication. Acid rain can be caused by a rise in atmospheric nitrogen.

The majority of ecosystems can tolerate low nitrogen levels since the majority of nitrogen is not biologically accessible in nature. Ecosystems become out of balance when humans significantly increase the quantity of nitrogen that is accessible through fertilizers, fertilizer use, and other means.

explain why metals conduct electricity in their solid forms but ionic compounds do not. you may use a picture to support your an
deff fn [24]

Explanation:

Ionic solids are defined as the solids in which atoms of opposite charge are held together by strong forces of attraction. As a result, in solid state these atoms are not present in free state.

Hence, they cannot move as ions from one place to another. On the other hand, metals are able to conduct electricity because of the presence of free electrons in it.

As we know that electricity is the flow of ions or electrons from one place to another. Therefore, metals are able to conduct electricity in their solid state.
