Answer 1

Answer:

A. Empirical formula => C₂H₄O

B. Molecular formula => C₄H₈O₂

Explanation:

From the question given above, the following data were obtained:

Mass of C = 0.273 g

Mass of H = 0.046 g

Mass of O = 0.182 g

Molar mass of compound = 88 g/mol

A. Determination of the empirical formula of the compound.

C = 0.273 g

H = 0.046 g

O = 0.182 g

Divide by their molar mass

C = 0.273 /12 = 0.023

H = 0.046 /1 = 0.046

O = 0.182 /16 = 0.011

Divide by the smallest

C = 0.023 / 0.011 = 2

H = 0.046 / 0.011 = 4

O = 0.011 / 0.011 = 1

Thus, the empirical formula of the compound is C₂H₄O

B. Determination of the molecular formula of the compound.

Empirical formula = C₂H₄O

Molar mass of compound = 88 g/mol

Molecular formula =?

Molecular formula = [C₂H₄O]ₙ

[C₂H₄O]ₙ = 88

[(12×2) + (4×1) + 16]n = 88

[24 + 4 + 16]n = 88

44n = 88

Divide both side by 44

n = 88 / 44

n = 2

Molecular formula = [C₂H₄O]ₙ

Molecular formula = [C₂H₄O]₂

Molecular formula = C₄H₈O₂

Why can't krypton and xenon separate during the separation of gases in the air?

Answers

Answer:

The remaining gas is a mixture of argon, neon, krypton, and xenon. Because these elements are chemically very unreactive, chemical means cannot be used to separate them.

Explanation:

Answer:

They're in Group 0 as they have full outer shells meaning they are chemically unreactive as they already have full outer shells meaning they don't want to lose or gain any electrons. Thus, they can't separate during the separation of gases in the air.
