Explanation:
Xylene exists as 3 isomers like Ortho ,para and meta xylenes
The wavelength of a photon that has an energy of E = 3.69×10−19 J is 5.42 x 10⁻⁷ m.
<h3>What do you mean by wavelength?</h3>
The space between corresponding points (adjacent crests) in adjacent cycles is known as the wavelength () of a waveform signal that is sent in space or down a wire.
The wavelength can be calculated by the given formula
E = hc/λ
Where, E is energy = 3.65 x 10⁻¹⁹ J
h is plank's constant = 6.626 x 10⁻³⁴ J.sec
c is speed of light = 2.9 × 10⁸ m/s
Putting the values in the formula
λ = (6.626 x 10⁻³⁴)(2.9 × 10⁸) / (3.65 x 10⁻¹⁹) = 5.42 x 10⁻⁷ m.
Thus, the wavelength, λ is 5.42 x 10⁻⁷ m.

<span>Answer is: atomic number
of resulting atom is 88.
Alpha particle is nucleus of a helium-4 atom, which is made of
two protons and two neutrons.
Nuclear reaction: ²³</span>²Th → ²²⁸Ra + α (alpha
particle).
Alpha
decay is radioactive decay in which an atomic
nucleus emits an alpha particle (helium nucleus) and transforms
into an atom with an atomic number that is reduced by
two and mass number that is reduced by four.
