Why can you see a corona during a total solar eclipse?

Chemistry
1 answer:
Mumz [18]2 years ago
7 0

Answer:

The corona shines only about half as brightly as the Moon and is normally not visible to the unaided eye, because its light is overwhelmed by the brilliance of the solar surface. During a total solar eclipse, however, the Moon blocks out the light from the photosphere, permitting eye observations of the corona.

The dipole moment of hcl is 1.03d. what is the dipole moment of hcl in c⋅m?
Margaret [11]

Answer: Dipole moment  =3.43\times 10^{-30} Cm

Explanation: Dipole moment is defined as product of magnitude of the charge and the distance between the charges of equal magnitude and opposite sign is called as dipole moment.

\mu= e\times d

\mu=\text{dipole moment}

e=\text{magnitude of charge}

d=\text{distance between the charges}

S.I unit of dipole moment is Debye (D).

Debye was defined as the dipole moment resulting from two charges of opposite sign but an equal magnitude of 10^{-10} stat coulomb (generally called e.s.u. (electrostatic unit) which were separated by 1 angstrom.(1 angstrom =10^{-8}cm)

1 Debye=10^{-18}\text{esu cm}

1 esu=3.35\times 10^{-10}C

1cm=10^{-2} m

1Debye=10^{-18}\times3.35\times 10^{-10}C\times 10^{-2}m

1Debye=3.35\times 10^{-30}Cm

1.03Debye=1.03\times 3.35\times 10^{-30}Cm

                       =3.43\times 10^{-30} Cm
