Answer:
The presence of hydrogen ions
Explanation:
Nitric acid is formed when hydrogen ions combine with nitrogen oxide ions leading to formation of a strong acid. Wheareas for strong bases the hydroxyl iins must be present, for strong acid, the hydrogen ions contribute to the acidity. Therefore, from the formula of nitric acid, it has hydrogen ions, an indicator of a strong acid.

We can exemplify with H2O (water)
H= nonmetalic
O= Nonmetalic
A bond with nonmetalic and nonmetalic is covalent bond.
Hope it helps!!

Answer: 0.4M
Explanation:
This would be much easier if we first analized what was given from the question. This is illustrated below:
C1 = 2M
V1 = 25mL
C2 =?
V2 = 125mL
C1V1 = C2V2
2x25= C2 x 125
Divide both side by 125, we have:
C2 = (2x25) /125
C2 = 0.4M
Therefore, the molarity of potassium bromide formed will be 0.4M
