Use the half-reaction method to write a balanced ionic equation for each reaction. All are basic solutions.
a. MnO4
–
(aq) + ClO2
–
(aq) → MnO2(s) + ClO4
–
(aq)
b. Cr3+(aq) + ClO–
(aq) → CrO4
2–(aq) + Cl–
(aq)
c. Mn3+(aq) + I–
(aq) → Mn2+(aq) + IO3
–
(aq)
d. Zn(s) + NO3
–
(aq) → NH3(aq) + Zn(OH) 4
2–
(aq)

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
