Sticky question: how do you separate molecules that are attracted to one another?.
lions [1.4K]

Answer:

Chromatography uses chromatography paper which is filter paper that is made of cellulose, a polymer. Cellulose is polar, therefore it attracts water molecules, as well as other polar substances. As the solvent reacts with the paper, it competes for the attraction of the molecules being separated.

A 6.175 gram sample of an organic compound containing only C, H, and O is analyzed by combustion analysis and 13.30 g CO2 and 5.
Bingel [31]

Answer:

Empirical and molecular formulas are the same, C₅H₁₀O₂.

Explanation:

Hello!

In this case, when determining the empirical and molecular formulas of organic compounds via combustion analysis, we first need to compute the moles of carbon and hydrogen via the yielded mass of carbon dioxide and water:

n_C=13.30gCO_2*\frac{1molCO_2}{44.01gCO_2}*\frac{1molC}{1molCO_2}=0.30molC\\\\n_H=5.447gH_2O*\frac{1molH_2O}{18.02gH_2O}*\frac{2molH}{1molH_2O}=0.60molH

Next, we need to compute the mass of oxygen by subtracting the mass of carbon and hydrogen to the mass of the sample of the compound:

m_O =6.175g-0.3molC*12.01gC/molC-0.6molH*1.01gH/molH =1.966gO

And consequently the moles:

n_O=0.12molO

Now, we need to divide the moles of each atom by the fewest moles, it in this case, those of oxygen to obtain the subscripts in the empirical formula:

C=\frac{0.30}{0.12} =2.5\\\\H=\frac{0.60}{0.12} =5\\\\O=\frac{0.12}{0.12} =1

Thus, the empirical formula, taken the nearest whole number is:

C_5H_{10}O_2

Now, if we divide the molar mass of the molecular formula (102.1 g/mol) by that of the empirical formula (102.1 g/mol) we infer they are both the same.

Best regards!

Igneous intrusion D is younger than layers B, C, and E according to
Maurinko [17]

Answer:

Law of cross-cutting relationships

Explanation:

This interpretation is based on the law of cross - cutting relationships.

This law states that "faults and fractures that cuts through a rock are younger than the rocks they cut through".

  • In a sequence of strata, the strata that are not cut through by these features are younger than the cross -cutting features.
  • The igneous intrusion is younger since it cuts through the rock layers.
