List the following bonds in order of increasing polarity (ionic character). Give the electronegativity values for each atom to j
barxatty [35]

Answer:

A = B < D < C

C - S

Cl - Cl

F ← H

Si → O

Explanation:

The polarity of a bond increases with the increase in the difference in electronegativity. The dipole moment is represented with an arrow pointing the more electronegative atom.

A: carbon-sulfur

C - S

ΔEN = |EN(C) - EN(S)| = |2.5 - 2.5| = 0

B: chlorine - chlorine

Cl - Cl

ΔEN = |EN(Cl) - EN(Cl)| = |3.0 - 3.0| = 0

C: fluorine – hydrogen

F ← H

ΔEN = |EN(F) - EN(H)| = |4.0 - 2.1| = 1.9

D: silicon - oxygen

Si → O

ΔEN = |EN(Si) - EN(O)| = |1.8 - 3.5| = 1.7

The order of increasing polarity is A = B < D < C.

Conversion of minus 1 coulomb meter in debye
Viktor [21]

Answer:

-1 Coulomb meter = -2.997 × 10²⁹ Debye

Explanation:

Given:

Coulomb meter = -1 CM

Find:

In debye

Computation:

We know that,

1 Coulomb meter = 299,792,458,178,090,000,000,000,000,000 Debye

So,

-1 Coulomb meter = -299,792,458,178,090,000,000,000,000,000 Debye

-1 Coulomb meter = -2.997 × 10²⁹ Debye

3. If the percent by volume is 2.0% and the volume of solution is 250 mL, what is the volume of solute in solution? (1 point) 0.
igor_vitrenko [27]
Volume percent = Volume of solute
                              ----------------------------------
                                Volume of the solution
  
                  2                    Volume of the solute
               -------   =           ------------------------------
                100                               250
                     
         Volume of the solute = 2 x 250
                                                ------------
                                                  100         

                                             =   5 mL.

Hope this helps!
