<u>Answer:</u> The speed of the electron is
<u>Explanation:</u>
To calculate the speed of electron for given wavelength, we use the equation given by De-Broglie's, which is:
where,
= De-Broglie's wavelength =
h = Planck's constant =
m = mass of the electron =
v = speed of the electron = ?
Putting values in above equation, we get:
Hence, the speed of the electron is
Hey there!
The answer is D, Salinity.
Salinity is the concentration of salt in water. Ocean water often has high salinity and this can contribute to things like upwelling and water density- but these all start from salinity.
Hope this helps!
MgCl2 because it is the only option in which a metal appears with a nonmetal. In this case, the metal transfers electrons to the nonmental because the metal has a lower ionization energy.
