Why does the sky change colors at sunset?

1 because the sun changes colors

2 because the atmosphere reflects colors

3 because long wavelengths are scattered the least

4 because short wavelengths are scattered the least

answer : 2.13 ×10^24 atoms

explanation :

- one mole of (s) contains avogadro’s number of atoms (6.02×10^23 molecules),

- using cross multiplication,

                      1 mol of (s)             →       6.02 ×10^23 atoms

                      3.54 mol of (s)         →                   ?

hence, the number of atoms in 3.54 mol s = 3.54 × 6.02 ×10^23 / 1 = 21.31 ×10^23 = 2.13 ×10^24 atoms ..

it is the 2nd law of universal gravitation.

it does have to do with bonds hope that
