The reason for adding a limited amount and then an excess amount is that initially a metal hydroxide may form which becomes soluble when more base is added and the metal complex forms.
In qualitative analysis is a common to add the base in drops and then in excess. When added in drops, the metal hydroxide is formed. This metal hydroxide is often insoluble.
After this metal hydroxide is formed, the base could be added in excess such that the metal hydroxide dissolves in the excess base by forming a complex.
For instance;
CuCl2(aq) + 2NaOH(aq) -------> Cu(OH)2(s) + 2NaCl(aq)
Cu(OH)2(s) + 2OH^-(aq) -------> [Cu(OH)4]^2+(aq)

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.

Answer:
d. Form ATP during glycolysis.
Explanation:
During oxidative phosphorylation, an oxidation-reduction reactions will happen and the electrons transferred and energy released will be used in the conversion of adenosine diphosphate (ADP) into adenosine triphosphate (ATP).
This happens as a step of glycolysis, wich is the process in which the organism breaks gluscose molecules to obtain energy.
