Calculate the energy of a photon of 765 nm wavelength light in J. a. 1.99 x 10⁻²⁵
b. 2.60 x 10⁻¹⁹
c. 2.60 x 10⁻²⁸
d. 1.52 x 10⁻³¹
e. 2.59 x 10⁻³⁷

2.6×10^-19 J/photon

Explanation:

E  of photon  =  h  ×  ν

where h= 6.63 × 10^-34 j.s

v= C ÷ λ

E = ( h × c) ÷ λ

E = (6.63 × 10^-34 × 3.00 ×10^8 )  ÷ ( 765 × 10^-9)

E = 2.6×10^-19 J/photon

yes they ca   is ur ansswerrr

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
