Ionization energy is the amount of energy required to remove the electron that is most loosely bound of an isolated gaseous atom to form a cation.
Electron affinity is the amount of energy released when an electron is added to a neutral atom or a molecule in a gaseous state to form negation ion.
The difference of ionization energy and electron affinity is ionization energy is the required energy to remove an electron from a neutral atom. Whereas, electron affinity is the energy change when a neutral atom attracts an electron to become a negative ion.

Fe has a charge of 2+ while O has a charge of 2-.
Formula: FeO
Answer:
one valence electron
Lithium has a single electron in the second principal energy level and so we say that lithium has one valence electron. Beryllium has two valence electrons.

We calculate for the number of moles of water given its mass by dividing the given mass by the molar mass.
n water = (36.04 g) / (18 g/mol)
n water = 2 mols
From the given balanced equation, every 6 moles of water produced will require 7 moles of oxygen.
n oxygen = (2 mols H2O) x (7 moles O2 / 6 moles H2O)
n oxygen = 2.33 mols O2
Answer:
b. Add NO gas
Explanation:
According with Le Chatelier´s principle, when a reactant is added the equilibrium is displaced to the product(s), to achieve the equilibrium again. Therefore, if NO is added in the reaction, it will be produced more of NO2(g).
