Explanation:
Geometric sequences are usually sequences that are found by multiplying a number by a fixed common ratio. This is different form an arithmetic sequence in which increment/decrements are achieved by addition or subtraction of a constant number.
To find the common ratio here 64, 16, - 4. 1. -1/4
Divide the second term by the first one:
common ratio =

B) ionic. Generally, metals and non-metals form ionic bonds that are stronger than covalent bonds due to the higher electronegativity difference.
Hey there!
The sample of NF₃ contains 8.02 moles fluorine atoms.
There are 3 fluorine atoms in each molecule, so there will be 1/3 of the moles of fluorine.
8.02 / 3 = 2.67
There are 2.67 moles of NF₃ in a sample that contains 8.02 moles fluorine atoms.
Hope this helps!
#1 is 95L balanced . #2 is 55^3G balanced.
