A sample of hydrogen gas has a pressure of 1.50 atm with a volume of 5.00 L, what is the pressure if the volume is expanded to 7
miss Akunina [59]

Answer:

The pressure is 0,97 atm

Explanation:

We apply Boyle Mariotte's Law, where for a certain mass of gas, at constant temperature, the pressure and volume vary inversely proportionally:            P1x V1 = P2 x V2 P2= (P1 x V1)/V2

P2 = 1, 50 atm x 5, 00 L /7,74 L

P2= 0, 97 atm

Suppose you have a 1:1:1 by weight mixture of three solid compounds, salicylic acid 4-nitroaniline naphthalene. You dissolve 1 g
choli [55]

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.

Select the fastest way to differentiate between the organic and aqueous layers of an extraction.a. Hold a white piece of paper b
valentinak56 [21]

Answer:

b. Add a few drops of one of the layers to a test tube containing 1 mL of water. Shake the test tube to determine the solubility of the layer in water

Explanation:

Option a is not true, it depends on the compound being extracted.

Option c is not true, although most of the solvents used in extractions have lower boiling point than water there are exceptions, for example toluene.

Option  d is not true. Again most of the solvents used in extractions are less dense than water, there are many exceptions, for example chloroform, so for equal volumes the chloroform layer will weigh more.

Option b. is the correct one.

One will test the  miscibility of the layer in water. If it inmiscible then one would know is the organic layer. If it is the aqueous layer then it will completely be miscible.
