The hydrogen ion concentration [H3O+] in an egg white containing 6.3 × 10-⁷M of [OH-] is 1.5 × 10-⁸M.
<h3>How to calculate [H3O+]?</h3>
The hydrogen ion concentration of a solution can be calculated as follows:
pOH = - log [OH-]
pOH = - log [6.3 × 10-⁷M]
pOH = - [-6.2]
pOH = 6.2
Since pOH + pH = 14
pH = 14 - 6.2
pH = 7.8
pH = - log [H3O+]
7.8 = - log [H3O+]
[H3O+] = 10-⁷:⁸
[H3O+] = 1.5 × 10-⁸M
Therefore, the hydrogen ion concentration [H3O+] in an egg white containing 6.3 × 10-⁷M of [OH-] is 1.5 × 10-⁸M.

Answer:
Here are some disadvantages
Explanation:
Hard water does not pose a health threat.
Hard water can contribute to dry skin and hair.
Hard water is unfit for washing as it is difficult to form lather with soap.
Trimming of kettles will take place due to the formation of magnesium and carbonates of calcium.

Answer:
(A) melting point, freezing point.
Explanation:
For the same substance: when matter is transitioning from solid to liquid <em>(melting)</em> or liquid to solid <em>(freezing)</em>, <em><u>its temperature is fixed at the melting/freezing point, which is the same temperature.</u></em>
