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.
Explanation:
Mole ratio of NaOH to H2O = 2 : 1
Moles of H2O = 1.85mol * (1/2) = 0.925mol.
Mass of H2O = 0.925mol * (18g/mol) = 16.65g.
F. None of the above [Cl^(-) is oxidized]
<em>No Cl atoms are available</em> to be oxidized, only Cl^(-)ions
2Cl^(-) → Cl_2 + 2e^(-)
The substance that <em>loses electrons</em> is oxidized.
Remember <em>OIL</em> RIG (<em>O</em>xidation<em> I</em>s <em>L</em>oss of electrons) and
<em>LEO</em> the lion says GER (<em>L</em>oss of Electrons is <em>O</em>xidation).
Butane undergoes combustion to produce carbon dioxide and water, expressed in the following reaction <span> C4H10 (g) + O2 (g) → 4CO2 (g) + 5H2O (g) . 1 mole of butane is to 4 moles of CO2. In this case, when 22.8 grams of butane or 0.393 moles of it, 69.18 grams of carbon dioxide is produced</span>
