Explanation:
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
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 (from period table)
1 mole = 6.02x10^23
In BCC unit cell:
(8 x 1/8)+ 1=2 per 1 unit cell
Mass: 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
1pm=10^-12m
1cm=10^-2m
1mL=1cm^3
density=mass/volume
density of V = 1.69x10^-22g÷2.837x10^-23mL
=5.957g/mL
=5.96g/cm^3

why are water-soluble vitamins less likely to be toxic compared to fat-soluble vitamins?
Answer:
Water-soluble vitamins are not stored in the body and are excreted in the urine quickly. Unlike water-soluble vitamins, fat-soluble vitamins are dissolved in fat and an excess of them would lead to toxicity if consumed in large amounts because it would lead to rancidity, and they are not easily excreted by urine like water-soluble vitamins.
Even when consumed in high doses, water-soluble vitamins are less likely to create problems since they are eliminated through urine rather than stored.
What are vitamins?Vitamins are defined as a collection of molecules required for healthy cell growth, development, and function. While some vitamins support healthy neurons and infection resistance, others may aid in correct blood clotting or food energy absorption.
Water-soluble vitamins are promptly eliminated in the urine and are not retained by the body. In contrast to water-soluble vitamins, which are easily eliminated by urine, fat-soluble vitamins are dissolved in fat. If ingested in excess, they can be harmful due to rancidity and cannot be easily expelled through urine.
Thus, even when consumed in high doses, water-soluble vitamins are less likely to create problems since they are eliminated through urine rather than stored.

Which of the following is NOT a conductor of heat?
A. a plastic pot handle
B. a copper pan
C. a metal spoon
A) A plastic pot handle.
Explanation:Metals are very good conductors of heat because they contain delocalised electrons that can flow through the metal, transferring heat.
Both a copper pan and a metal spoon are made of metals, so are very good conductors of heat.
Plastic is an insulator, the opposite of a conductor. This makes it very bad at conducting heat, which is why it is used as the handle (it stops you burning yourself when you hold the pot). The answer is therefore A.
Soil forms layers when mixed with water. sand is found above what ?
Answer:
Explanation:
Clay:)Se dispone de un recipiente de 60 litros que contiene un gas de 1,64 atm y a una temperatura de 100K ¿Cuántos moles de gas hay? *
En este caso, dado que se describe un gas del que se conoce el volumen (60L), la presión (1.64 atm) y la temperatura (100K), es posible usar la ecuación del gas ideal para calcular los moles que hay presentes a estas condiciones:
[tex]PV=nRT[/tex]
Ahora, despejamos las moles del gas como sigue:
[tex]n=\frac{PV}{RT}[/tex]
Finalmente, reemplazamos los valores dados, teniendo en cuenta que R es 0.08206 en atmosferas, litros y Kelvin:

a 750 sample of technetium-99 decays in 4 half lifes, how much of the sample will remain?
Answer:
93.75
Explanation:
In first half life 750×1/2 will remain
In second one half from that remained at the end of first half life will remain
That is 1/2 × 750×1/2
likewise at the end of 3rd half life 1/2 × 1/2 ×750×1/2 remains
at the end of 4th half life 1/2 × 1/2 × 1/2 ×750×1/2 remains
1/2 × 1/2 × 1/2 ×750×1/2 = 93.75 remains.
You can also use the equation
Remainder = X × 1/2^n .
This saves time
n= no. of half lives
X= initial amount
so in this case 1/2^4 × 750 = 93.75
If I am calculating the volume in pv=nrt
Then, how do I know what units it is in coz normally it would be m3 but how do I know that it's not dm3
Explanation:
If you use the SI units for P, n, R and T ( In Pa, mol, JK-1mol-1 and K respectively) you'll end up with a Volume with m3 units. So if you have others in different units first convert them into the units I mentioned above and you will definitely get the answer in m3.
discuss the solubility differences between the halogens and the halides in both hexane and water. be sure to define what a halogen and halide are to foundation your discussion.
Halides are ionic substances while halogens nonpolar substances. Hence, halides dissolves in water while halogens dissolve in hexane.
A halogen is an element in group seventeen. The name halogen means salt former. This name came about because many of the halogens form salts. Halides are salts formed by the halogens.
Halogens are diatomic covalent molecules. As such, they are nonpolar molecules and can only effectively interact with nonpolar solvents. Benzene is a nonpolar solvent hence it acts as an effective solvent for the halogens.
The halides are polar compounds hence they do not dissolve in nonpolar solvents such as hexane. Rather, halides dissolve in polar solvents such as water due to dipole - dipole interaction between the ions in the halide and the dipoles in water.

During secondary active transport, the movement of one substance down its electrochemical gradient provides the force to move another substance up its electrochemical gradient. When both substances move in the same direction the mechanism is referred to as a(n)
Given what we know about the mechanisms surrounding the biological movement of substances, we can confirm that when two substances in a secondary active transport move in the same direction, it is called a symport.
A secondary active transport harnesses the electrochemical energy generated by its movement of one substance, to aid the movement of the other. These movements can be of two types, depending on the directions:
AntiportSymportAn antiport transport will move both substances in opposite directions, meaning one out of the cell and one into the cell. The transport described in the question is that of a symport, given that it moves both substances in the same direction.

type the max number of electrons that can be present in each shell or sub below
n = 5 shell __
n = 2 shell __
n = 2 l = 0 sub: __
n = 2 / 1 sub: __
3d sub: __
2s sub: __
5f sub: __
Explanation:
The maximum no. of electrons in a shell is given by. 2n^2 .
So for
n= 5 , 2× 5× 5 = 50
n=2 , 2×2×2 = 8
For a sub shell the maximum no. of electrons possible is given by 2(2l + 1)
So for n= l= 0
2 [(2×0) +1] = 2
for n=2 l=1
2 [(2×1) + 1] = 6
3d
d sub shell has l= 2 quantum number
Therefore 2[ (2×2) + 1] = 10
2s
s sub shell has l=0 quantum number
2 [(2×0) +1] = 2
5f
f sub energy level has l=3 quantum number
So 2[ (2×3) +1 ] = 14
The azimuthal quantum numbers for the sub shells are as follows
( s ---> 0
p----> 1
d----> 2
f ----> 3 )
