A photon has an energy of 1.10 x 10 -13 j. What is the photon's wavelength? What type of electromagnetic radiation is it?

lawyer [7]

Answer:

λ = 0.002 nm

The given photon is either x-ray or gamma ray because the range of x-ray and gamma ray is 1 nm-0.1 pm.

Explanation:

Given data:

Energy of photon = 1.10 × 10⁻¹³ J.

Wavelength of photon = ?

Solution:

Formula:

E = h.c / λ

λ = h. c / E

λ = 6.626 × 10⁻³⁴ j. s × 3×10⁸ m/s / 1.10 × 10⁻¹³ J.

λ = 19.878 × 10⁻²⁶m / 1.10 × 10⁻¹³ J

λ = 18.071 × 10⁻¹³ m

λ = 18.071 × 10⁻¹³ × 10⁹

λ = 18.071 × 10⁻⁴ nm

λ = 0.002 nm

The given photon is either x-ray or gamma ray because the range of x-ray and gamma ray is 1 nm-0.1 pm.

Which term describes this reaction? upper c upper h subscript 3 upper b r (a q) plus upper o upper h superscript minus (a q) rig

Veronika [31]

The reaction is a substitution reaction since bromide ion was replaced by hydroxide ion.

<h3>What is a chemical reaction?</h3>

A chemical reaction is a change which results in a the permanent rearrangements of the atoms and constituents of a substance such that new substances are formed.

The given reaction is a as follows:

$CH_3Br (aq) + OH^{-} (aq) \rightarrow CH_3OH (aq) + Br^{-} (aq) \\$

Bromide ion was replaced by hydroxide ion.

Therefore, the reaction is a substitution reaction.
