Answer:
wwe are asked to prive the atomic pavking factor APF for BCC is 0.68
solution
APF is given by equation (3.3) in the form
APF =nVs/Vc
whenn is the number of atoms per unit cell and for BCC n=2.0, Vs is the volume of the atom and it is given by 43π3³ and Vc is the volume of the unit cell and for BCC Vc=a³ where a is the side of the cube. From equation 3.4
we could get a by
a=4R/√3
where R is the radius of the atom. Now let us olug the expression inyo equation (1) to get APF
APF = nVs/Vc
=2.0(4/3πR³) / (4R/√3)³
=2.0(4/3πR³) / (4/√3)³ R³
=0.68
Answer:
Explanation: The main difference between Genetic and Hereditary Diseases is that genetic disease is a condition which occurs due to an abnormality in the individual’s genome while a hereditary disease is a condition caused by a mutation of a gene which can be characteristically transmitted from one generation to another, also The main difference between these two terms lies in the fact that hereditary diseases have the potential of being carried from one generation to another whereas a genetic disease can either be hereditary or not, but there will always be a mutational change in the genome.
Answer:
Oxidizing agent: ZnO
Reducing agent: C
Substance Oxidizes: CO
Substance Reduced: Zn
Explanation:
<em>Oxidation</em> means the gain of oxygen atom but the lose of hydrogen atom.
<em>Reduction</em> means the lose of oxygen atom but the gain of hydrogen atom.
This is a <em>redox</em> reaction since both reactions are taking place.
...acid rain can eat away metals, it’ll corrode them, but to affect the rate?? I’m pretty sure some elements can neutralize acid, perhaps slow down its reaction, like limestone for example. A lake lined with limestone will neutralize any acid fallen into the water. But as for a statue, I’m not sure but it must be something similar... sorry I can’t be more of a help :\
