The hcl(g) molecule has a bond length of 127 pm and a dipole moment of 1.08
Roman55 [17]

Let us assume that this molecule is 100 percent ionic. In that case, the charges are distinguished by a bond length.

h = Q × r

= (160 × 10⁻¹⁹ c) (127 × 10⁻¹² m) (10 / 3.336 × 10⁻³⁰ cm)

= 6.09 D.

The actual dipole moment is = 1.08 D

Therefore, the percent ionic character is,

= 1.08 D / 6.09 D × 100

= 17.7 %.

You are using a standardized 0.1250 M solution of sodium hydroxide to determine the concentration of sulfuric acid. After pipett
Sergeu [11.5K]

Answer: Thus the concentration of the sulfuric acid is 0.1201 M

Explanation:

H_2SO_4+2NaOH\rightarrow Na_2SO_4+2H_2O

To calculate the concentration of acid, we use the equation given by neutralization reaction:

n_1M_1V_1=n_2M_2V_2

where,

n_1,M_1\text{ and }V_1 are the n-factor, molarity and volume of acid which is H_2SO_4

n_2,M_2\text{ and }V_2 are the n-factor, molarity and volume of base which is NaOH.

We are given:

n_1=2\\M_1=?\\V_1=10.00mL\\n_2=1\\M_2=0.1250M\\V_2=19.22mL

Putting values in above equation, we get:

2\times M_1\times 10.00=1\times 0.1250\times 19.22\\\\M_1=0.1201M

Thus the concentration of the sulfuric acid is 0.1201

in the modern wave-mechanical model of the atom, the orbitals are regions of the most probable location of
irina [24]

The orbital is the probable location of the electron of an atom.


Always remember the difference between Bohr and wave-mechanical model in terms of electrons!  

Your questions answer is Electron!  

But you should also know Bohr said electrons are in orbitals in a fixed proportion, but modern wave mechanical disagrees with this and said electrons are arranged in a very complex random proportion in a region called orbital!  

Hope this helped


have a smiley day (:
