2 Fluorine atoms covalently bonded with each other, each sharing an equal number of a single, one valence electron to achieve a stable octet, would form a diatonic fluorine gas. It is a diatomic molecule, a molecule consisting of 2 atoms that are the same, in this case fluorine.
Both of them are a hope this helps
<span>1.) a. 20 ÷ 4 ? means ? × 4 = 20 </span>→ replace ? with 5.<span>
b. 2,725 ÷ 5 ? means ? × 5 = 2,725 </span>→ replace ? with 545<span>
c. ? ÷ 5 = 0 </span>→ replace ? with 0.
2) 1,475 / 25 = 59
They used 59 boxes for this year.
3) 18 per haircut ; 70 per perm
4,608 = 18h + 70(36)
4,608 - 2,520 = 18h
2,088 = 18h
2,088/18 = h
116 = h
Grace did 116 haircuts.
4) 575 + 13(118) = 575 + 1,534 = 2,109 total expense.
5) 2,240 miles / 320 miles = 7 tanks of gas used.
7 tanks * 39 = 273 cost of the gas used.
1 mole ------------ 6.02 x10²³ molecules
? mole ----------- 1.505 x10²³ molecules
1.505x10²³ / 6.02x10²³ => 0.25 moles
hope this helps!
I believe the correct answer from the choices listed above is option D. The modern atomic model is sometimes called the electron cloud or quantum mechanics model. It <span>uses complex shapes of orbitals (sometimes called electron clouds), volumes of space in which there is likely to be an electron. </span>
Hope this answers the question. Have a nice day.
