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:
A
Explanation:
energy stored in chemical bonds of molecules
<u>Answer:</u> The standard Gibbs free energy of the given reaction is 6.84 kJ
<u>Explanation:</u>
For the given chemical equation:

The expression of
for above equation follows:

We are given:

Putting values in above expression, we get:

To calculate the equilibrium constant (at 25°C) for given value of Gibbs free energy, we use the relation:

where,
= standard Gibbs free energy = ?
R = Gas constant = 8.314 J/K mol
T = temperature = ![25^oC=[273+25]K=298K](https://tex.z-dn.net/?f=25%5EoC%3D%5B273%2B25%5DK%3D298K)
= equilibrium constant at 25°C = 0.0632
Putting values in above equation, we get:

Hence, the standard Gibbs free energy of the given reaction is 6.84 kJ
Ionic bonds result from transfer of electrons, whereas covalent bonds are formed by sharing
