Answer is: <span> two samples have in common same amount of substance and same number of particles.
1) There are same amount of substance in both beakers:
n(Zn) = 1 mol.
n(ZnCl</span>₂) = 1 mol.
2) There are same number of particles (atoms, molecules, ions) in both beakers:
N(Zn) = n(Zn) · Na.
N(Zn) = 1 mol · 6.023·10²³ 1/mol = 6.023·10²³ atoms of zinc.
N(ZnCl₂) = n(ZnCl₂) · Na.
N(ZnCl₂) = 1 mol · 6.023·10²³ 1/mol = 6.023·10²³ molecules of zinc(II) chloride.
Na - Avogadro number.
It is non-polar molecule.
CF₄ - dipole moment = 0D
A wavelength's frequency and energy (E) drop as it becomes longer. You may conclude from these equations that the wavelength grows shorter as the frequency rises. The wavelength lengthens as the frequency drops.
Since frequency and wavelength are inversely related to one another, the wavelength of the wave falls as frequency increases.
