Answer: XF8

Explanation:

Empirical Formular shows the simplest ratio of elements in a compound.

 Xe = 46.3%             F  = 53.7%

Divide the percentage composition of each element by the atomic  mass.

Xe = 46.3/ 131.3                      F= 53.7/ 19

      = 0.353( approx)               =  2.826 (approx)

Divide through with the smallest of the answers gotten in previous step.

 Xe = 0.353 / 0.353                F = 2.826/ 0.353

       =  1                                       = 8.0

Empirical formular = XF8

An inventor claims to have developed a new perfume that lasts a long time because it doesn't evaporate. Comment on this claim.
zaharov [31]

Answer:

C

Explanation:

Perfume needs to evaporate in order to smell.  If this perfume didn't evaporate, it would stay as a liquid and never smell.  

It wouldn't be D, as no toxic perfumes is sold.

It's not A because perfume doesn't have to be pressurized in order to not evaporate.

It's not B, as it is a hasty conclusion to the claim.  Plus, if the perfume did have an odor, even while not evaporating, the sales would be low as the product is that good.

What is the difference/similarities between the periodic table developed by Mendeleev versus the one developed by Moseley?
kotegsom [21]

Both designed a periodic table of elements- Mendeleev designed the first one in order of atomic mass and Moseley designed the modern one in order of atomic number. ... Isotope- Because of the notation and the 13 is not the atomic mass on the periodic table so it is the same element just a different form.
