Vanadium crystallizes in a body-centered cubic lattice, and the length of the edge of a unit cell is 305 pm. What is the density

of V
Chemistry
1 answer:
Anestetic [448]2 years ago
5 0

Answer:

5.96 g/cm^3

Explanation:

Corner atom = 1/8

Atoms in center = 1

Atoms in face of the cube= 1/2  

Molar mass of V = 50.94 g/mol <em>(from period table)</em>

1 mole = 6.02x10^23

<em>In BCC unit cell:</em>

(8 x 1/8)+ 1=2 per 1 unit cell

<em>Mass: </em>2(50.94g)/6.02x10^23 = 1.69x10^-22 g/unit cell

305pm=(305x10^-12m÷10^-2m) x (1mL÷1cm^3)

           = 2.837 x 10^-23 mL

<em>1pm=10^-12m</em>

<em>1cm=10^-2m</em>

<em>1mL=1cm^3</em>

<em></em>

density=mass/volume

density of V = 1.69x10^-22g÷2.837x10^-23mL

                    =5.957g/mL

                    =5.96g/cm^3

How do atoms and molecules of elements and compounds combine in chemical reactions?
solong [7]

Answer:

A compound is a unique substance that forms when two or more elements combine chemically. Compounds form as a result of chemical reactions. The elements in compounds are held together by chemical bonds. A chemical bond is a force of attraction between atoms or ions that share or transfer valence electrons

Genetic equilibrium is the state in which allele frequencies do<br> not change in a<br> Check it
Vikentia [17]

Answer:

Genetic equilibrium is the state in which allele frequencies do

not change in a generation over generation.

Explanation:

Genetic equilibrium can be described as a situation which arises when a certain allele or genotype remains constant for a species generation over generations. Genetic equilibrium can be maintained if no external factors like mutations affect the population of the species. The phenomenon of natural selection and evolution need to be stopped if a genetic equilibrium is to be maintained. Hardy-Weinberg theorem is the mathematical depiction of genetic equilibrium.
