Answer : The chemical name of the compound is, nickel(III)oxide.
Explanation :
The rules for naming the chemical name of the compound :
- First element in the formula is named first and keep its element name.
- Gets a prefix if there is a subscript on it.
- Written the oxidation state by the us of roman numeral.
- Second element is named second.
- Use the root of the element name plus suffix (-ide).
- Always use a prefix on the second element.
In the given compound, the nickel is the cation and first element in the formula and the oxidation state of nickel is, (+3). The second element is oxygen which is named as oxide.
Thus, the chemical name of the compound is, nickel(III)oxide.

Answer:
Explanation:
The stereochemical structures of the two compounds of the fumarase-catalyzed reaction are in the attachment below. The reaction been referred to is illustrated in the equation below
HOOCCH=CHCOOH + H₂O ==> HOOCCH₂CH(OH)COOH
The compounds attached are trans-2-butenedioate (which is one of the reactants) and (s)-2-hydroxysuccinate (which is the product formed)
Note that stereoisomers are isomers that differ in spatial orientation, thus there are other isomers that could contain the same atoms and have slightly but different spatial orientation such as cis-2-butenedioate and (r)-2-hydroxysuccinate

Explanation:
This question is incomplete but some general explanation provides a clear answer to what is been asked in the question.
An ionic/electrovalent compound is a compound whose constituent atoms are joined together by ionic bond. Ionic bond is a bond involving the transfer of valence electron(s) from an atom (to form a positively charged cation) to another atom (to form a negatively charged anion). The atom transferring is usually a metal while the atom receiving is usually a non-metal.
For example (as shown in the attachment), in the formation of NaCl salt, the sodium (Na) transfers the single electron (valence) on it's outermost shell to chlorine (Cl) which ordinarily has 7 electrons on it's outermost shell but becomes 8 after receiving the valence electron from sodium. It should also be noted that Na is a metal while Cl is a non-metal.
