Broad-spectrum pesticides: kill beneficial organisms in addition to the targeted pest. are readily broken down into safe materia
belka [17]

Answer:

kill beneficial organisms in addition to the targeted pest

Explanation:

The use of pesticides have emerged as one of the main options used in the control of invertebrate pests in different parts of the world. Organophosphate is the mostly used form of pesticide in places like Australia. There have been reported issues of crops losses from the incidences of pests, despite the increase in the use of pesticides. Broad spectrum pesticides end up kill non-target invertebrate species together with the insects and mites they are out to eliminate

<h3>What is a hybrid?</h3>

Hybrid is defined as an organism or plants that has two different kinds of alleles for a  given trait and it is one that is known to be heterozygous for that trait.

A vital function of proteins is seen in their role as enzymes, and this is one that are needed to catalyze at least almost  all biological processes. Regulation of enzyme activity is said to plays a vital role in managing  cell behavior.

Gregor Mendel as a result of his work on pea plants was known to be the man who found out about the fundamental laws of inheritance (genetic theory).

Answer: 44.5 g of H_2O will be produced from the given masses of both reactants.

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}\times{\text{Molar Mass}}    

\text{Moles of} NH_3=\frac{65.8}{17}=3.87moles

\text{Moles of} O_2=\frac{65.8}{32}=2.06moles

4NH_3(g)+5O_2(g)\rightarrow 4NO(g)+6H_2O(g)

According to stoichiometry :

5 moles of O_2 require 4 moles of NH_3

Thus 2.06 moles of O_2 will require=\frac{4}{5}\times 2.06=1.65moles  of NH_3

Thus O_2 is the limiting reagent as it limits the formation of product and NH_3 is the excess reagent.

As 5 moles of O_2 give = 6 moles of H_2O

Thus 2.06 moles of O_2 give =\frac{6}{5}\times 2.06=2.47moles  of H_2O

Mass of H_2O=moles\times {\text {Molar mass}}=2.47moles\times 18g/mol=44.5g

Thus 44.5 g of H_2O will be produced from the given masses of both reactants.
