The mass will stay the same because of the conservation of mass
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:
It retains the properties of the substances that make it up
Explanation:
Mixture show the properties of substances like a mixture of iron filling and sulphur show properties of both
Strong acids have a higher PH while weaker acids have a lower PH
I'm other words, acidic bases have a higher PH whilst less acidic bases have lower PH
Answer:
D) The water will freeze into cubes again.
Explanation:
When the ice cubes is left on a counter, it will melt as the forces that make its molecules stick together is broken.
If that tray is put back in the freezer again, the water will freeze into cubes again.
When water freezes, the molecules slow down and settle into its place, arranging in a regular shape that can be appeared as crystals (ice cubes).
