Answer:
The magnitude of the partial charges in HBr is approximately 1.95 × 10^-19 C.
Step-by-step explanation:
The magnitude of the partial charges in a polar covalent bond can be determined using the formula:
μ = q × d
where μ is the dipole moment, q is the magnitude of the partial charges, and d is the bond length.
In this case, the dipole moment of HBr is given as 0.82 debye, which is equivalent to 0.82 × 3.336 × 10^-30 Cm (since 1 debye = 3.336 × 10^-30 Cm). The bond length is given as 1.41 angstroms, which is equivalent to 1.41 × 10^-10 meters.
Plugging these values into the formula, we get:
0.82 × 3.336 × 10^-30 Cm = q × 1.41 × 10^-10 meters
Solving for q, we get:
q = (0.82 × 3.336 × 10^-30 Cm) / (1.41 × 10^-10 meters) ≈ 1.95 × 10^-19 C
Therefore, the magnitude of the partial charges in HBr is approximately 1.95 × 10^-19 C.
