What orbital does the quantum numbers n=4 l=2 ml=2 describe

Chemistry
1 answer:
Natasha2012 [34]2 years ago
6 0

Answer:

Orbital designation

for Principle Quantum number n=4, this is the shell number & corresponds to N shell, (shells are designated K,L,M,N)

for Angular Momentum number l=2, this is the orbital level corresponding to d, given that l can be any integer 0-(n-1), for( 0,1,2,3 )corresponds to (s, p, d, f)

The orbital designation is 4d

for Magnetic Quantum number ml, the suborbitals correspond to -l through l, (-2,-1,0, 1,2)

for ml=-1 the suborbital -1 in the 4d sub shell with electron spin state ms=-1/2

Explain whether nuclear or mitochondrial DNA is better for identifying a specific person
hodyreva [135]

Answer:-

Nuclear DNA is inherited from all ancestors. But mitochondrial DNA is inherited from a single lineage. The DNA inside of mitochondria (called mtDNA) unlike DNA inside the nucleus, comes from only mothers.

It is not a mixture of our parent’s DNA, and each person’s mtDNA is nearly identical to his or her mother’s mtDNA.

Thus only nDNA being more unique is more useful for identifying in forensics. In cases where nDNA is not sufficient, mtDNA is used.

423.3 mL of gas is at 49.2 C. It is compressed to a volume of 79 mL. What is the new temperture. Express your answer in Kelvin.
zzz [600]

Answer: 60.1K

Explanation:

Initial volume of gas V1 = 423.3mL

Initial temperature T1 = 49.2°C

Convert temperature in Celsius to Kelvin

( 49.2°C + 273 = 322.2K)

Final temperature T2 = ?

Final volume V2 = 79mL

According to Charle's law, the volume of a fixed mass of a gas is directly proportional to the temperature.

Mathematically, Charles' Law is expressed as: V1/T1 = V2/T2

423.3mL/322.2 = 79mL/T2

To get the value of T2, cross multiply

423.3mL x T2 = 322.2K x 79mL

423.3mL x T2 = 25453.8

T2 = (25453.8/423.3mL)

T2 = 60.1K

Thus, the new temperature of the gas is 60.1K

Which of the following will increase entropy in a reaction?
Lapatulllka [165]

B. Heating up the reaction will increase the entropy of a reaction.

<h3>What is entropy?</h3>

Entropy is the measure of the degree of disorderliness of a system.

Entropy is also the measure of a system's thermal energy per unit temperature that is unavailable for doing useful work.

S = ΔH/T

where;

  • S is entropy
  • ΔH is energy input
  • T is  temperature

Entropy increases in reactions in which the total number of product molecules is greater than the total number of reactant molecules.

However, entropy increases as temperature increases. Thus, heating up the reaction will increase the entropy of a reaction.
