Hurry please quick summary

I think that work is being done on the books because they are being moved to their proper location and they will be sorted properly rather than lying on a table. Without lifting or carrying, you could sort the books by their genre or title name on the bookshelf so it will be sorted much more efficiently.

I’m not sure if this is the answer you are looking for but I hope it helps :)

Lorelai discovers a compound that is 64.8 g C, 13.62 g H, and 21.58 g O. What is the empirical formula of Lorelai's compound
jenyasd209 [6]

The empirical formula of Lorelai's compound is C₄H₁₀O

<h3>Data obtained from the question</h3>
  • C = 64.8 g
  • H = 13.62 g
  • O = 21.58 g
  • Empirical formula =?

<h3>How to determine the empirical formula</h3>

Divide by their molar mass

C = 64.8 / 12 = 5.4

H = 13.62 / 1 = 13.62

O = 21.58 / 16 = 1.35

Divide by the smallest

C = 5.4 / 1.35 = 4

H = 13.62 / 1.35 = 10

O = 1.35 / 1.35 = 1

Thus, the empirical formula of the compound is C₄H₁₀O

A scientist discovers a new type of polymer. What must be true about this polymer?
DochEvi [55]

The correct answer is D

a polymer is a substance made up of large molecules with repeating sub units called monomers.

A is incorrect because its a ring structure which means it cannot form the long chain that is exhibited by polymers.

B is incorrect because the double bonds will cause saturation, hence no monomer can bond to another monomer to form the large molecule.

C is incorrect because the large molecule  has repeating sub-units hence only specific types of molecules can be present, and it is usually carbon and hydrogen.
