Answer:
152 pm
Explanation:
According to the question, we can estimate the bond length from the given values of the atomic radii. This now is the upper limit of the bond length for the molecule.
Since we have that;
Atomic radius of H= 37.0 pm
Atomic radius of Br = 115.0 pm
Bond length = Atomic radius of H + Atomic radius of Br
Bond length = 37.0 pm + 115.0 pm
Bond length = 152 pm

Answer: 0.123 M
Explanation:
According to the neutralization law:

where,
= molarity of
solution = ?
= volume of
solution = 15.00 ml
= molarity of
solution = 0.100 M
= volume of
solution = 18.44 ml
= valency of
= 1
= valency of
= 1


Therefore, the concentration of the unknown HBr solution is 0.123 M
