The dipole moment (μ) of HBr (a polar covalent molecule) is 0.838D (debye), and its percent ionic character is 12.4 % . Estimate

the bond length of the H−Br bond in picometers.
Note that
1 D=3.34×10−30 C⋅m and
in a bond with 100% ionic character, Q=1.6×10−19 C.

Note: q = 1.6 × 10−19 C

       1D = 3.34 × 10−30Cm3.34 × 10−30 Cm

         μ = 0.838D

Asked: r?

Answer: 1. Using comparison 1.11.1 in the formula:

         μ = qr

          r = r = μ / q

          r = [0.838D (3.34 × 10−30 C⋅m / 1D)] / (1.6 × 10−19 C) * 0.124

          r = 1.41 x10 ^ -10 m.

Thus, the estimated bond length of the H bond BR bond in a picometer is 1.41 x10 ^ -10 m.

<h2>Further Explanation </h2>

Molecular geometry is the arrangement of atoms that make up molecules in three dimensions. Molecular geometry determines several properties of substances including reactivity, polarity, substance appearance, color, magnetism, and biological activity. The angle between the bonds that make up the atom depends only weakly on the molecule, that is, they can be understood as local and therefore transferable.

In molecular geometry, bond length or bond distance is the average distance between the nuclei of two atoms bound in a molecule. This is one of the properties that can be removed from bonds between atoms of a fixed type, which are relatively independent of the molecule. Bond length is related to bond order: when more electrons participate in bond formation, the bond becomes shorter. Bond length is also inversely proportional to bond strength and bond dissociation energy: all other factors being equal, stronger bonds will be shorter. In a bond between two identical atoms, half the bond distance is equal to the covalent radius.

Factors that affect the bond length

The factors that determine bond length are:

  1. Covalent radius
  2. Electronegativity
  3. Order of ties

<span>When two electrical charges, of opposite sign and equal magnitude, are separated by a distance, a dipole is established. The size of a dipole is measured by its dipole moment (</span>μμ). Dipole moment is measured in Debye units, which is equal to the distance between the charges multiplied by the charge (1 Debye equals 3.34×10−30Cm3.34×10−30Cm). The dipole moment of a molecule can be calculated by Equation 1.11.1:

μ = qr

where

<span> <span>μ⃗ μ→ is the dipole moment vector</span> <span>qiqi is the magnitude of the ithith charge, and</span> <span>r⃗ ir→i is the vector representing the position of ithith charge.</span> </span>

 

r = μ/q

<span>r = [0.838D(3.34×10−30 C⋅m/ 1D)]/ (1.6×10−19 C) *0.124
</span> r = 1.41 x10^-10 m

True or false if an object displaces 50 ml of water the object's volume is 50mL
andrew11 [14]

Answer:

True

Explanation:

The volume of water displaced by an object completely submerged is its actual volume. It implies that in the container the object create a space of size for itself which is the volume of the object. This approach is used in calculating the density of many irregular solids from their measured masses.

Pls helpits rlly hard
victus00 [196]

Answer:

5: 0.16

6: 50

Explanation:

Question 5:

We can use the equation density = mass/ volume.

We already have the mass (12g), but now we need to find the volume of the cylinder.

The equation for this is πr²h

So we know the radius is 2 and the height is 6.

π x (2)² x 6 = 24π = 75.398cm³

Now we can use the density equation above:

12/75.398 = 0.1592g/cm³ = 0.16g/cm³.

Question 6:

This time, we have to rearrange the equation density = mass/ volume to find the mass.

We know mass = density x volume.

From the question, the density is 2.5g/mL and the volume is 20mL.

Following the equation above, we do 2.5 x 20 to get 50g.
