Many repeating, simple subunits are joined together. What is the most likely

Chemistry
1 answer:
Hatshy [7]3 years ago
6 0

Answer:

O a polymer

Explanation:

When many repeating simple subunits are joined together, this results into a polymer.

The simplest unit or smallest unit of any substance is called a monomer. When many units of a monomer joins together, a polymer results.

  • For proteins, the monomeric unit is amino-acid.
  • When they combine they form longer chain molecules called proteins.
  • For carbohydrates, the monomeric unit is called glucose.
  • When they are combined they give us a wide range of carbohydrate molecules.

gulaghasi [49]

Answer:

a. 3.79e5 J

b. Decrease.

Explanation:

Hello!

a. In this case, since the heat involved during a compression-expansion isothermal process is computed via:

Q=nRTln(\frac{V_2}{V_1} )

Now, since the final volume is one third of the initial one:

V_2=\frac{V_1}{3}

So we can plug in now:

Q=139mol*8.3145\frac{J}{mol*K}*298.15K*ln(\frac{\frac{V_1}{3} }{V_1} )\\\\Q=-3.79x10^5J

b. In this case, the relationship between initial and final volume is:

V_2=2.2V_1

So the heat interaction is now:

Q=139mol*8.3145\frac{J}{mol*K}*298.15K*ln(\frac{2.2V_1 }{V_1} )\\\\Q=2.72x10^5J

It means that the heat interaction decrease on the contrary process, it means that in a. heat was released by 3.79e5 J and in b heat is absorbed by 2.72e5 J.

Best regards!

Select the following statements that are true. Select all that apply.
geniusboy [140]

Answer:

The statements which are true among these are: (a),(b) and (c) because,

(a) The simplest organic compounds which contains only carbon and hydrogen atoms are called hydrocarbons.

(b) The IUPAC naming of organic compounds have some rules for the naming of compounds, which consists of

  • Finding the longest chain present in the compound called parent chain.
  • A prefix for any substituent attach to the parent chain.

And lastly a suffix for the type of bond that molecule have.

(c) Isomers are the compound which same same molecular formula but different arrangement of molecules, due to this different arrangement they have different physical and chemical properties.
