Answer:
The speed of an electron is 0.01908 m/s.
Explanation:
De-Broglie wavelength is given by:
where, = wavelength of a particle
h = Planck's constant =
m = mass of particle
v = velocity of the particle
Velocity of an electron = v
Mass of an electron =
Wavelength of electron is twice the displacement in seconds which is velocity of an electron.
Then.wavelength of an electron =
v = 0.01908 m/s
The speed of an electron is 0.01908 m/s.

Answer:
option D is correct
Explanation:
no of moles in 3 grams of HCL=3/36=0.08
if 1 mole of HCL require 1 mole of NaOH then 0.08 moles required 0.08 moles of NaOH
mass of 0.08 moles of NaOH=moles*molar mass=0.08*40=3.2 grams
so 3 grams are required in the reaction
