Answer:
9.133×10^-6 m
Explanation:
A photon is the smallest discrete amount or quantum of electromagnetic radiation. It is the basic unit of all light. Photons are always in motion and, in a vacuum, travel at a constant speed to all observers of 3 x 10^8 m/s.
From the question, the following details were supplied;
Energy of the photon (E) = 4.61×10^−19 J
Speed of light (c) = 2.99×10^8 m/s
Plank's constant (h) = 6.626×10^−34 J⋅s
Wavelength of the photon (λ)= ??? The unknown
From
E=hc/λ
λ= hc/E
Substituting values
λ= 6.626×10^−34 × 2.99×10^8/ 4.61×10^−19
λ= 91.33×10^-7 m
λ= 9.133×10^-6 m

thanks again I appreciate you I'm sorry but you ok if I invite to you in my prayers for you and Mani
Answer:
Br₂ + 2NaI → 2NaBr + I₂
Explanation:
This is the reaction:
Br₂ + 2NaI → 2NaBr + I₂
It's a sort of redox, where the bromime is reducted to bromide and iodide is oxidated to iodine.
Br₂ + 2e⁻ → 2Br⁻
2I⁻ → I₂ + 2e⁻
