It has a fixed mass
it does not change with the shape of the container
it cannot be compressed
it has fixed atom and molecules and limited to very small displacement
only vibrational motion occur in the molecules of solid .

Which of the following aqueous solutions has the highest boiling point?A. 1.25 M Ca(NO3)2B. 1.25 M KNO3C. 1.25 M CH3OHD. 2.50 M
Drupady [299]

Answer:

Ca(NO3)2 has the highest boiling point ( option A)

Explanation:

Step 1: Data given

A. 1.25 M Ca(NO3)2

B. 1.25 M KNO3

C. 1.25 M CH3OH

D. 2.50 M C6H12O6

Step 2: Calculate highest boiling point

The boiling point depends on the van't Hoff factor

This shows the particles produced when the substance is dissolved. For non-electrolytes dissolved in water, the van' t Hoff factor is 1.

Ca(NO3)2 → Ca^2+ + 2NO3- → Van't Hoff factor = 3

KNO3 → K+ + NO3- → Van't Hoff factor = 2

CH3OH is a non-elektrolyte → Van't Hoff factor = 1

C6H12O6 is a non-elektrolyte → Van't Hoff factor = 1

Ca(NO3)2 has the highest boiling point

Which is the best definition of nonpolar covalent bond?​
kondor19780726 [428]

Answer:

It is one of the covalent bonds in which the electrons are shared equally; therefore, dipole moment exists between the atoms in a molecule and there is no charge separation between the atoms in a molecule.

Which of the following would you except to see in the death of a star that is less than 0.5 solar mass
Ket [755]

B. White Dwarf.

<h3>Explanation</h3>

The star would eventually run out of hydrogen fuel in the core. The core would shrink and heats up. As the temperature in the core increases, some of the helium in the core will undergo the triple-alpha process to produce elements such as Be, C, and O. The triple-alpha process will heat the outer layers of the star and blow them away from the core. This process will take a long time. Meanwhile, a planetary nebula will form.

As the outer layers of gas leave the core and cool down, they become no longer visible. The only thing left is the core of the star. Consider the Chandrasekhar Limit:

Chandrasekhar Limit: 1.4 \;M_\odot.

A star with core mass smaller than the Chandrasekhar Limit will not overcome electron degeneracy and end up as a white dwarf. Most of the outer layer of the star in question here will be blown away already. The core mass of this star will be only a fraction of its 0.5 \;M_\odot, which is much smaller than the Chandrasekhar Limit.

As the star completes the triple alpha process, its core continues to get smaller. Eventually, atoms will get so close that electrons from two nearby atoms will almost run into each other. By Pauli Exclusion Principle, that's not going to happen. Electron degeneracy will exert a strong outward force on the core. It would balance the inward gravitational pull and prevent the star from collapsing any further. The star will not go any smaller. Still, it will gain in temperature and glow on the blue end of the spectrum. It will end up as a white dwarf.

What is the correct 1 letter code for the amino acid sequence Glutamic Acid-Histadine-Tyrosine Select one: a. E-H-Y b. G-H-T c.
EastWind [94]

Answer:

a. E-H-Y

Explanation:

A group of three nucleotides is called a codon that codes for a specific amino acid in the protein. There are 20 essential amino acids present in human body and are required in the diet.

Each amino acid is given a one-letter code that makes the study of amino acid sequences easy. One letter code for the given amino acid sequence Glutamic Acid-Histidine-Tyrosine is E-H-Y in which E is code for Glutamic Acid, H is a code for Histidine, and Y is a code for Tyrosine.

Hence, the correct answer is "a. E-H-Y".
