Answer:

This is because Corn is grown on land and has important values to man .These values include as a source of food for man and animals. It is also used as raw materials for the production of certain goods such as flour etc.

It is an energy resource because fermentation of corn gives rise to ethanol fuel which is used as a source of power to run machines and other equipment.

Which reagents are appropriate to carry out the conversion shown?

lesantik [10]

A reagent us a chemical substance applied in a chemical reaction to bring about a change in the chemical reaction process. The reagent that is appropriate to carry out the conversion is Ethanol (CH3CH2OH).

Organic Reactions are reactions taking place in organic compounds and they can take various forms such as electrophilic addition reaction or nucleophilic substitution reactions.

From the assumed diagram below, the reaction takes place in an unimolecular nucleophilic reaction SN1 mechanism in which a racemic mixture produce an organic compound and an enantiomer.

For the reaction to take place, the best organic reagent to us is known as ethanol (CH3CH2OH). This is because the organic reagent is a solvent that acts as a Nucleophile.

In the reaction, bromine (Br) is the leaving group, after it detaches from the racemic compound, it forms a carbonation in which the Ethanol CH3CH2OH attacks at the carbonation site.

Therefore, we can conclude that the Reagent necessary to carry out the conversion is Ethanol (CH3CH2OH)

Decide if the following statements are true or false.

Andre45 [30]

Answer: (a). Ca has a larger ionization energy than $Ca^{2+}$ - False

(b). Ar has a more exothermic electron affinity than Cl - False

(c). Ba has a larger ionization energy than $Ba^{2+}$ - False

(d). Br is smaller than $Br^{-}$ - True

(e). $Sr^{2+}$ is larger than Sr - False

Explanation:

The amount of energy required in order to remove the most loosely bound electron from an atom or ion is called ionization energy.

An atom with large size will have low ionization energy.

The size of Ca is more as compared to $Ca^{2+}$ ion. Hence, Ca atom will have less ionization energy than $Ca^{2+}$ ion.

Similarly, Ba atom has less ionization energy than $Ba^{2+}$ ion.

When an electron is added to an atom then the amount of energy released is called electron affinity.

Ar is a noble gas and its octet is already complete. So, it has less exothermic electron affinity than Cl because Cl needs one more electron to complete its octet.

When an element gain electrons then it acquires a negative charge and it is called an anion. The size of an anion is always larger than its parent atom.

For example, Br is smaller than $Br^{-}$ .

When an element lose electrons then it acquires a positive charge and it is called a cation. The size of a cation is always smaller than its parent atom.

For example, $Sr^{2+}$ is smaller than Sr.

Thus, we can conclude that

(a). Ca has a larger ionization energy than $Ca^{2+}$ - False

(b). Ar has a more exothermic electron affinity than Cl - False

(c). Ba has a larger ionization energy than $Ba^{2+}$ - False

(d). Br is smaller than $Br^{-}$ - True

(e). $Sr^{2+}$ is larger than Sr - False
