Answer:
C. Copper (II) nitrate
Explanation:
It's an inorganic compound that forms a blue crystalline solid
Ions are the charged species of the atom that carries an extra or less electron. The chemical name of the compound Cu(NO₃)₂ based on polyatomic ions is copper (II) nitrate. Thus, option C is correct.
What is an ionic compound?An ionic compound is a type of chemical compound that is characterized by the presence of the ions or the charged species that results in electrostatic forces leading to the ionic bond formation.
The copper (II) nitrate compound is an example of an ionic compound as the Cu atom is metal and nitrogen and oxygen atoms are the non-metals. The metallic part of the compound carries a +2 charge while the non-metallic part consists of a negative charge.
Therefore, option C. Cu(NO₃)₂ can be named chemically as copper (II) nitrate.

How can one determine that a redox reaction will be nonspontaneous?
A. The oxidation potential has a negative value.
B. The reduction potential plus oxidation potential is positive.
C. The reduction potential plus oxidation potential is negative.
D. The reduction potential has a positive value.
Answer:
C: The reduction potential plus oxidation potential is negative
Explanation:
Redox reaction is a combination of reduction and oxidation reactions. A redox reaction can be nonspontaneous if the sum of reduction and oxidation potential is negative. Thus, option C is correct.
What is a redox reaction?Redox reaction involves the transfer of the electron from an electron donor to an acceptor. This lead to the change in the oxidation number, and the charge on the atom or the molecules.
A redox reaction has been said to be nonspontaneous if the reduction and the oxidation half of the reactions add to a negative value. As there is an external voltage supplied to the reactants that have to result in a negative potential.
Therefore, option C. the redox reaction is nonspontaneous if the addition of the oxidation and reduction adds to a negative value is correct.
