Answer:

Explanation:

The periodic table is a table that classifies elements based on their chemical properties and physical properties into groups (columns) and periods (rows). Elements in the same group have similar chemical properties, for example group I elements (alkali earth metals) have the same valency (electrons in the outermost energy level). The table also shows the physical properties of an element, for example whether it is a metal or a non metal; e.g group 1, 2 and 3 elements are all metals while group 4 are metaloids, group 5,6 and 7 are non metals and group 8 elements are noble gases with an octet configuration. Additionally, the table also reveals the order reactivity depending on the eas of gaining electrons (for non metals) and loosing electrons (for metals).

When explaining about structural classifications to a group of students, the instructor discusses the peptides and proteins. The

stepladder [879]

Answer:

There are approximately 200 amino acids.

Explanation:

Proteins are usually larger than peptides. In addition, proteins contains amino acids which are about 50 and more than while the amino acids in peptides are just between 2 and 50. On the other hand, growth hormone which is also known as somatotropin is a type of peptide cell regeneration, growth, and reproduction. The number of amino acids in the growth hormones are approximately 200.

Draw structures from the following names, and determine which compounds are optically active:(c) 1,2-dibromo-2-methylbutane

dolphi86 [110]

The given compound 1,2-dibromo-2-methylbutane is an optically active compound .

Because this compound does not have plane of symmetry (POS) and center of symmetry (COS) i.e. does not have di-symmetry . And also forms non superimposable mirror image . the compound is optically active .

It has chiral center.

Here , the chiral carbon is attached to the 4 distinct groups such as : methyl , ethyl , bromine , bromomethane .

<h3>What is di-symmetry?</h3>

Di-symmetry is that which have no center of symmetry and plane of symmetry and alternate axis of symmetry .

<h3>Chiral center :</h3>

Have Sp3 hybridized center (4sigma bond ) .

4 distinct group is attached to the chiral atom. form non -superimposable mirror image .

<h3>What is optical isomerism ?</h3>

Same molecular formula and same structural formula . also have same physical and chemical properties .

They differ in their behavior towards plane polarized light (ppl) .

Which type of substance can conduct electricity in the liquid phase but not in the solid phase?

VikaD [51]

Ionic compound, this is because the ions in a compound consist of a metal and a nonmetal... Or cation and anion. This means that they have opposite charges, so when they are in liquid form they allow for movement of electrify because they are free flowing. In contrast, as a solid they are tightly attracted and compacted so a charge cannot be carried through. Hope that helps!
