Answer:
The equation that tends to answer this question, (omitting the presence of water) is:
Fe (ClO4) 3 -----------> Fe (+3) + ClO4 (-1)
Explanation:
The numbers that we see in parentheses would be the oxidation numbers of each compound, in the case of iron, iron acts with an oxidation number of +3, and in the case of perchlorate it would be -1.
The stoichiometric name according to IUPAC (most widely used chemical nomenclature) is iron perchlorate.
Answer:
D. F
Explanation:
Electron affinity is defined as the change in energy (in kJ/mole) of a neutral atom (in the gaseous phase) when an electron is added to the atom to form a negative ion. In other words, the neutral atom's likelihood of gaining an electron.
The electron affinity values of the following elements is given;
Electron Affinity of Hydrogen is 72.8 kJ/mol.
Electron Affinity of Lithium is 59.6 kJ/mol
electron affinity of carbon is 153.9 kJ mol‑1
Electron Affinity of Fluorine is 328 kJ/mol
The electron affinity of neon is 0 kJ mol‑1.
When nonmetals gain electrons, the energy change is usually negative because they give off energy to form an anion (exothermic process); thus, the electron affinity will be negative.
Nonmetals have a higher electron affinity than metals, meaning they are more likely to gain electrons than atoms with a lower electron affinity.
That explains why florine seems to have the highest electron affinity value.

1.a- sodium(Na) b-nickel(Ni) c-iron (Fe)
<span>SO3
for the formal charges, we have:
for the single-bonded oxygens F.C. = 6 - [1/2(2) + 6] = -1
for the double-bonded oxygen F.C. = 6 - [1/2(4) + 4] = 0
for the sulfur F.C. = 6 - [1/2(8) + 0] = 2
Again, the formal charges add to zero. The oxidation numbers of O and S are -2 and +6, respectively. Note the three resonance forms!</span>
