Answer:
The frequency of the photon that can dissociate dichlorine is 6.02×10¹⁴ Hz
Explanation:
The energy of a photon is given by the equation:
E=h·f
E=3.99×10⁻¹⁹ J/molecule
h (Planck's constant)=6.626×10⁻³⁴ m²·kg/s
∴ f=E/h
=6.02×10¹⁴ s⁻¹= 6.02×10¹⁴ Hz
Answer:
Charge
Explanation:
A surplus (having "extra") or deficit (having "fewer") of electrons possessed by an object. A charge can cause attractive or repulsive forces which can be observed in some cases (e.g. pith balls, bits of plastic).
