Answer:
4.99 x 10⁻⁷ meters or 499 nanometers
Explanation:
Use the formula:
λ = c/ν, where λ = wavelength, c = the speed of light (it's constant, 2.998 x 10⁸ m/s), and ν = frequency
λ = (2.998 x 10⁸ m/s)/(6.01 x 10¹⁴ 1/s)
λ = 4.98835 x 10⁻⁷
Round to nearest hundreth and you get 4.99 x 10⁻⁷ meters, or 499 nanometers.
the resulting compound is Li+ -------- Cl- in a crystalline lattice structure.
so first choice is wrong as its not a double bond
third choice is wrong as its not a ball-and-stick
fourth choick is also wrong as its not a triple bond
correct ans is The chemical compound will have a network structure.
I don’t quite understand this one sorry
Answer:
its all of them ✨
Explanation:
i idk why there its all of them tho i promise you
I think the correct answer from the choices listed above would be the first option. The angle between the hydrogen atoms in water (H2O) is slightly less than expected for a tetrahedral shape. This is because of the extra electron repulsion from the lone pairs. Hope this helps.
