<h3>Monoatomic vs Polyatomic Ions</h3>
In chemistry, monoatomic ions are ions that consist of only a single type of atom. They are usually positive or negatively charged and are otherwise known as simple ions. Examples include , , and
Polyatomic ions, on the other hand, are ions that consist of more than one atom, unlike monoatomic ions. The two or more atoms are covalently bonded and the entire structure behaves like a single chemical entity in reactions. Polyatomic ions are otherwise known as molecular ions.
Examples of polyatomic ions are , , , , , and
Thus, from the diagram:

The list of 4 things can increase the rate of a reaction is:
surface area of a solid reactant.
concentration or pressure of a reactant.
temperature.
nature of the reactants.
presence/absence of a catalyst.
Hope this helped :)

Answer:
4.68x10⁻⁵N
Explanation:
The pH is defined as -log [H⁺]. If an acid has a pH of 4.33, [H⁺] is:
pH = -log [H⁺]
4.33 = -log [H⁺]
10^(-4.33) = [H⁺]
4.68x10⁻⁵M = [H⁺]
The [H⁺] is in molarity units, that is mole / L. Normality has as units equivalent / L. As the equivalent in an acid-base reaction is defined as the number of moles of H⁺, in this case:
4.68x10⁻⁵M = <em>4.68x10⁻⁵N</em>
