Answer:
[H⁺] = 3.16 × 10⁻⁵ mol/L
Explanation:
Given data:
pH of solution = 4.5
Hydrogen ion concentration = ?
Solution;
pH = -log [H⁺]
we will rearrange this formula:
[H⁺] = 10∧-pH
[H⁺] = 10⁻⁴°⁵
[H⁺] = 3.16 × 10⁻⁵ mol/L
the temperature is decreased

Explanation:
potassium belongs to group IA of the periodic table.
Explanation:
A molecule with a triple bond will have a linear geometry as the angles between the bonds will be 180 degrees. Hence, it will be a linear geometry.
For example, a molecule of dinitrogen (
) has nitrogen atoms bonded through triple bond as follows.
:N ≡ N:
Since valency of nitrogen is 5 therefore, each nitrogen will have one lone pair of electrons.
