A student is given five samples and told they are lysine (an amino acid), lactose (a disaccharide), insulin (a protein hormone),

RNA and fat. The samples are in test tubes marked 1-5, but the student doesn’t know which compound is in which tube. The student is instructed to identify the contents of each tube. In her first test, she tries to hydrolyze a portion of the contents of each tube. Hydrolysis occurs in all tubes except tube 5. In the next test, she finds that tubes 3, 4, and 5 are positive for nitrogen but only tube 3 gives a positive result for the presence of sulfur. In the next test the student shows that the compound in tube 4 contains a high percentage of phosphate. In the final test the student shows that compound 1 is hydrophobic. Base on these data, identify what is in each tube.

Answer:

The Content in the tubes is:

tube 1:<em> Fat</em>

<em>tube 2: Lactose</em>

tube 3: Insulin

tube 4: RNA

tube 5: Lysine

Explanation:

tube 1: Fat is always not compatible with water it means hydrophobic

tube 2: For rejection of the other tubes the last molecule to assigned a tube is lactose due to we do not have a specific test information for tube 2

tube 3: The insulin has a two disulfide bonds and is the only molecule with sulphur atoms.

tube 4: The nitrogen based compounds that belongs to the RNA are binded with phosphate groups all around its chain, so the presence of phosphate indicates that is RNA.

tube 5: Because was the only one who does not hydrolyse it is an aminoacid.  

finally it says that in the tubes 3, 4 and 5 has nitrogen, the only 3 compound with nitrogen are Lysine, insulin and RNA.

A que temperatura se produce el punto de fusión
Sholpan [36]

Answer:

<h2>32°F /0°C </h2>

Explanation:

At what temperature does the melting point occur?

32°F /0°C

(32°F − 32) × 5/9 = 0°C

At temperatures above 32°F (0°C), pure water ice melts and changes state from a solid to a liquid (water); 32°F (0°C) is the melting point. For most substances, the melting and freezing points are about the same temperature.

Is Melting Point affected by temperature?

Melting point, the temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached. More heat then will convert the solid into a liquid with no temperature change.

Rank the given compounds based on their relative Bronsted acidities.
Law Incorporation [45]

Answer:

Explanation:

As the size of the halogen increases their acidity increases. Though HF being a weak acid is a stronger acid than water. H-NH2 is a base, while H-CH3 can be made to produce H+.
