Explain the optical activity of malic acid? Draw a pair of stereoisomers of malic acid.​

Chemistry
1 answer:
mr_godi [17]2 years ago
6 0

Under standard temperature and pressure, the optical activity of malic acid changes in the following ways:

  1. Wavelength of light
  2. Magnitude
  3. Temperature
  4. Concentration of solvent.

<h3>What is an optical activity?</h3>

An optical activity is also referred to as optical rotation and it can be defined as the ability of a substance or chemical compound to rotate the plane of polarization of a beam of plane-polarized light that passes through it.

<h3>What is malic acid?</h3>

Malic acid refers to an organic compound (dicarboxylic acid) that is typically made by all living organisms and its molecular formula is C_4H_6O_5. Malic acid is considered to be one of the most satisfactory substances to be used when studying optical activity because of its chemical properties such as having single asymmetric carbon atoms.

Under standard temperature and pressure, the optical activity of malic acid changes in the following ways:

  1. Wavelength of light
  2. Magnitude
  3. Temperature
  4. Concentration of solvent.

<h3>The stereoisomeric forms of malic acid.​</h3>

In Science, there are two (2) stereoisomeric forms of malic acid and these include:

  • L-enantiomers
  • D-enantiomers

Which of the following is true about matter
SashulF [63]

Answer: b- it is always a substance

Explanation: matter can be any liquid, gas, or solid that takes up space so the answer cannot be C or D. For answer number A to be true, you would have to remove the word more, because matter just has mass and takes up space it does not have "more mass"

Radioactive cobalt-60 is frequently used in treating cancer. It took 24 years for a 10 gram sample to decay to 0.625 grams. What
-BARSIC- [3]

Answer:

Half life is 6 years.

Explanation:

T½ = In2 / λ

Where λ = decay constant.

But N = No * e^-λt

Where N = final mass after a certain period of time

No = initial mass

T = time

N = 0.625g

No = 10g

t = 24 years

N = No* e^-λt

N / No = e^-λt

λ = -( 1 / t) In N / No (inverse of e is In. Check logarithmic rules)

λ = -(1 / 24) * In (0.625/10)

λ = -0.04167 * In(0.0625)

λ = -0.04167 * (-2.77)

λ = 0.1154

T½ = In2 / λ

T½ = 0.693 / 0.1154

T½ = 6.00 years.

The half life of radioactive cobalt-60 is 6 years

Write the advantages of modern periodic table write as more as you can and don't copy the same thing​
Tema [17]

Answer:

the advantages of modern periodic tables are given below and explained.

  1. position of hydrogen:since hydrogen has the least atomic number i.e 1 ,it is kept in group 1 of modern periodic table, but still controversial due to its. dual characteristics since it shows the characteristics of borh group 1 and group 17.
  2. position of isotopes :isotopes are element having the same atomic number but different atomic weight . Without any doubt all isotopes of one element and kept in one place.
  3. position of lanthanide and acnitinides: element of Lanthanides series and element of Actinides series are kept below the main block of the periodic table as they have different properties from other elements.
  4. correction of periodic law: some elements do not obey mendeleev periodic law , but when they are arranged according to atomic number they obey the modern periodic law.
  5. position of alkali metals and coinage metals : in modern periodic table , alkali metal are kept in group IA and coinage metals are in group.

hope this helped you☺️

any confusion then comment it and let me know.

actually as I say these points say that the modern periodic table is better than mendeleev periodic table so, don't get confused.
