The energy required to split apart dichlorine according to the equation is 3.99 × 10-19 j/molecule. cl2(g) → 2cl(g) calculate the frequency (hz) of the photon that can dissociate dichlorine. express answer in scientific notation.

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

hi,

the answer is d, it has indefinite shape but definite volume.

hope this !

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
