The dipole measured for HI is 0.380 D. The bond distance is 161 pm. What is the percent ionic character of the HI bond?
Feliz [49]

Answer:

Percent ionic character of HI bond is 4.91%.

Explanation:

<h3>Given Data:</h3>

Measured Dipole = 0.380D

bond distance = d = 161pm = 1.61*10^-8 cm

<h3>Calculation:</h3>

% ionic character is determined by following equation:

% ionic= (dipole measured/dipole calculated)*100

Now,

Dipole(calc)=qd

Dipole(calc)= (1.6*10^{-19}*3*10^{9})esu  *1.61*10^{-8}cm

(In above step 3*10^8 is multiplied to convert coulomb into esu)

Dipole(calc)=7.728*10^{-18} esu*cm

As,

10^{-18}esu*cm= 1D

So,

Dipole(calc)=7.728D

Now we can % ionic character using above equation:

%ionic=(0.380D/7.728D)*100

% ionic character=4.91%

Leucippus and Democritus proposed the "first" atomic view of matter. They arrived at this view based on
erik [133]

Answer:

C) philosophical and intuitive speculation

Explanation:

Hi

Leucippus and Democritus proposed the concept of an atom based on philosophical speculation as a way of explaining reality with the scarcity of data available at that time.

The ideas of  Leucippus and Democritus were rejected at that time but later retaken by Dalton when proposing his atomic model.

Success with your homework.
