Answer:
B. 3+
Explanation:
When Fe²⁺ loses an electron, it becomes an Fe³⁺ ion.
The loss of an electron in an atom makes the atom becomes positively charged. Further losing electrons makes the atom more positive.
For the given ion;
Fe²⁺ if it loses an electron more, it becomes Fe³⁺.
The expression is given as:
Fe²⁺ → Fe³⁺ + e⁻
Answer:

Explanation:
The unbalanced nuclear equation is

We can insert the subscripts, because these are the atomic numbers of the elements

That leaves only the superscript of He to be determined,
The main point to remember in balancing nuclear equations is that the sums of the superscripts must be the same on each side of the equation.
Then
27 + x = 31, so x = 31 - 27 = 4
Then, your nuclear equation becomes

Molecule
Explanation:
The molecular formula HOH is an example of a molecule.
A molecule is the smallest particle of a substance (element or compound) capable of independent existence.
Molecules can be:
- Monoatomic with one atom e.g Neon, Argon
- Diatomic with two atoms e.g Nitrogen gas N₂
- Polyatomic e.g ozone O₃
The word molecule can also be used to refer to a covalent compound that has discrete or separate units.
The formula HOH or H₂O is a separate covalent that has an independent existence.
