B. They are usually better conductors than nonmetals
Answer:
3Zn(s) + 2FeCl₃(aq) → 2Fe(s) + 3ZnCl₂ (aq)
Explanation:
This is a redox reaction where solid iron is formed by the reaction of Zn and Iron(III) chloride. We called redox because the iron is reduced and the zinc is oxidized.
The reactants are: Zn(s) and FeCl₃(aq)
The products are: ZnCl₂(aq) and Fe(s)
Zn(s) → Zn²⁺(aq) + 2e⁻ Oxidation
Fe³⁺(aq) + 3e⁻ → Fe(s) Reduction
The e- are unballanced so we multiply the half reactions:
(Zn(s) → Zn²⁺(aq) + 2e⁻) . 3 → 3Zn(s) → 3Zn²⁺(aq) + 6e⁻
(Fe³⁺(aq) + 3e⁻ → Fe(s)) . 2 → 2Fe³⁺(aq) + 6e⁻ → 2Fe(s)
When we sum the half reactions, the electrons can be cancelled:
3Zn(s) + 2Fe³⁺(aq) + 6e⁻ → 2Fe(s) + 3Zn²⁺(aq) + 6e⁻
Balanced equation: 3Zn(s) + 2FeCl₃(aq) → 2Fe(s) + 3ZnCl₂ (aq)

Answer:
Explanation:
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion. Both atoms are joint together by electrostatic interaction and ionic compound sodium chloride is formed.
Covalent bond:
It is formed by the sharing of electron pair between bonded atoms.
The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive.
For example:
In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive and both bonded atoms connected together through covalent bond.
