The ion present in the solution is Iron(II) (Fe\(^{2+}\)). When aqueous sodium hydroxide (NaOH) is added to a solution containing iron(II) ions, a dirty green precipitate of iron(II) hydroxide, (Fe(OH)\(_2\)), forms. This precipitate is insoluble in excess sodium hydroxide.

The chemical formula C\(_2\)H\(_4\) represents ethene (also known as ethylene), which is the simplest alkene containing a double covalent bond between two carbon atoms.During addition polymerization, the double bond between the carbon atoms in the ethene monomers breaks under high pressure and temperature. These monomers link together in a long chain of repeating units to form polyethene (or polyethylene), a widely used plastic.

In the scientific method, a hypothesis is a tentative explanation or an educated guess that can be tested through experimentation. When a hypothesis is rigorously tested and supported by a significant amount of evidence within the limits of what is currently known, it is elevated to the status of a theory.

The empirical formula is defined as the chemical formula that represents the simplest whole-number ratio of the atoms of each element present in a compound. For this reason, it is also frequently referred to as the simplest formula.

The general formula for the alkyne homologous series is C\(_n\)H\(_{2n−2}\), where n is the number of carbon atoms. The first member of the series has n=2 (ethyne), as a minimum of two carbon atoms is required for a triple bond. The 5th member of the alkyne series is hexyne (C\(_6\)H\(_{10}\)).

The empirical formula is defined as the chemical formula that represents the simplest whole-number ratio of the atoms of each element present in a compound. For this reason, it is also frequently referred to as the simplest formula.

The boarding fee per session was N250,000 before it was reduced to N165,000. This information can be found on page 6 of the novel.

The VP, Mrs Apeh, instructed the Chemistry teacher, Mr Justus Anabel, to conclude the national assembly. This can be found on page 5 of the novel.

The VP's phone rang incessantly as she tried to console Mr Bepo. THe calls were from worried parents who had heard different rumours about the incident. Mrs Apeh, at that point, realised the best she could do was to call the MD. This can be found on page 6 of the novel.
