We will see that the volume of the unit cell is 144,070,699.06 pm^3

<h3>How to get the volume of a body-centered cubic unit cell?</h3>

In a body-centered cubic unit cell, the side length of the cube is given as:

S = \frac{4}{\sqrt{3} } *R

Where R is the radius of the atom.

And the volume of a cube is the side length cubed, then we can see that the volume of our cube will be:

V = S^3 = (\frac{4}{\sqrt{3} }*227pm)^3

Solving that we get:

V  = (\frac{4}{\sqrt{3} }*227pm)^3 = 144,070,699.06pm^3

This is the approximated volume of the unit cell.

Alpha helices are a type of secondary structure in proteins. What is the length of a 69.0 69.0 kDa single‑stranded α‑helical pro
Veronika [31]

Answer : The  length of protein will be, 94.1 A⁰

Explanation :

First we have to calculate the amino acid residue.

\text{Amino acid residue}=\frac{\text{Length of single strand of protein}}{\text{Mean residue mass}}

Given:

Length of single strand of protein = 69.0 kDa

Mean residue mass = 110 Da

\text{Amino acid residue}=\frac{69.0kDa}{110Da}=\frac{69000Da}{110Da}=627.3

Now we have to calculate the number of turns in protein.

\text{Number of turns in protein}=\frac{\text{Amino acid residue}}{3.6\text{amino acid per turn of the alpha-helix}}

As there are 3.6 amino acid per turn of the alpha-helix.

\text{Number of turns in protein}=\frac{627.3}{3.6}=174.25

Now we have to calculate the length of the protein.

\text{Length of protein}=\text{Number of turns in protein}\times \text{Length of each turn}

As, we know that the length of each turn = 0.54 A⁰

\text{Length of protein}=174.25turns\times \0.54\AA=94.1\AA

Thus, the length of protein will be, 94.1 A⁰

Does the reaction of a main-group metal oxide in water produce an acidic solution or a basic solution? Write a balanced equation
Fynjy0 [20]

<u>Answer:</u> The main group metal produce a basic solution in water and the reaction is MO+H_2O\rightarrow M(OH)_2

<u>Explanation:</u>

Main group elements are the elements that are present in s-block and p-block.

The metals that are the main group elements are located in Group IA, Group II A and Group III A.

Oxides are formed when a metal or a non-metal reacts with oxygen molecule. There are two types of oxides which are formed: Acidic oxides and basic oxides.

  • Acidic oxides are formed by the non-metals.
  • Basic oxides are formed by the metals.

When a metal oxide is reacted with water, it leads to the formation of a base.

The general formula of the oxide formed by Group II-A metals is 'MO'

The chemical equation for the reaction of metal oxide of Group II-A and water follows:

MO+H_2O\rightarrow M(OH)_2

Hence, the main group metal produce a basic solution in water and the reaction is MO+H_2O\rightarrow M(OH)_2
