Suppose you have a 1:1:1 by weight mixture of three solid compounds, salicylic acid 4-nitroaniline naphthalene. You dissolve 1 g

ram of this mixture in diethyl ether, and place a tiny drop of the ether solution on a TLC plate. After developing the TLC plate, you see three spots. Which compound would would you expect to have the largest Rf value

Answer:

The correct answer is - 4-nitroaniline.

Explanation:

It is given that all three solid compounds salicylic acid + 4-nitroaniline + naphthalene are equal in the ratio in the mixture and then 1 gram of this mixture is dissolved in the diethyl ether and run a drop of the solution on TLC plate. This plate shows three spots.

The salicylic acid and naphthalene would stay dissolved in the diethyl ether solution due to the 4-nitroaniline could be extracted by adding aqueous acid and involve in the aqueous layer and thus spot of 4-nitroaniline would be with largest Rf value.

Amiraneli [1.4K]

Answer:

Covalent network solids are formed by networks or chains of atoms or molecules held together by covalent bonds. Consists of sp3 hybridized carbon atoms, each bonded to four other carbon atoms in a tetrahedral array to create a giant network. Examples of network covalent solids include diamond and graphite (both allotropes of carbon), and the chemical compounds silicon carbide and boron-carbide.

What are the values for % Cl and % F, respectively, for Sample II?
horsena [70]

Answer:

Explanation:

The mass percentages of chlorine and fluorine:

  Given:

Mass of chlorine = 5.753g

 Mass of fluorine = 9.248g

Find the total of the masses given:

   Total mass = mass of chlorine + mass of fluorine = 5.753 + 9.248 = 15.001g

% of Cl = \frac{mass of chlorine}{total mass} x 100

% of Cl = \frac{5.753}{15.001} x 100 = 38.35%

% of F =  \frac{mass of fluorine}{total mass} x 100

% of F =  \frac{9.248}{15.001} x 100 = 61.65%
