The depletion of natural resources, the use of chemical and fuel in factories that increased air and water pollution , and increased the use of fossil fuels.
The answer for the first question would be water. It is the substance that is a compound since it is made up of different elements. For the second item, i think the best answer is phosphorus and nitrogen. They are the limiting nutrients. For the last item, the correct answer is reservoirs.
Answer:
Negatively charged ions are called anions, and an anion is formed when an atom gains an electron. Thus, the atom has an extra charge of electrons,
Explanation:
so it becomes negatively charged.
Clay with rice in freezer the freezer would make the clay and rice harden
Answer:
Electrophilic aromatic substitution is the reaction in which the bromobenzene is present with the presence of the nitronium ions and results in the formation of para-bromonitrobenzene.
Explanation:
Bromobenzene in the presence of nitronium ions preferntially forms para-bromonitrobenzene rather than meta or the ortho product.
so. here the reaction been mentioned refers to Electrophilic aromatic substitution.
Electrophilic aromatic substitution: An organic reaction is referred as the aromatic substitution.
In this type of organic reaction a system is present which is an organic system to which an atom gets attached which get replaced by an electrophile.
It is one of the most important reactions of the field synthetic organic chemistry.
the usage of these reactions are in synthesis of the most important intermediates which are used as the precursors in agrochemical, industrial and pharmaceutical products.
