What is the second quantum number for one of the electrons in the 4p energy
sublevel of bromine?
O A. 1 = 1
B. /= 3
C. /= 2
D. /= 4
Answers
Answer:
D. l=1
Explanation:
The second quantum number for one of the electrons in the 4p energy
sublevel of bromine is 1=1. Therefore, the correct statement is option A.
What is the second quantum number?The second quantum number also called the azimuthal quantum number describes the shape of the orbital.
The possible values of l for a given value of the principal quantum number (n) range from 0 to (n-1) where n is a principal quantum number that describes the size of the orbital and the energy of the electron, where possible values of l determine the shape of the orbital.
In the 4p energy sublevel of bromine, n is equal to 4 because the energy sublevel and fourth principal energy level are associated. For p orbitals, the possible values of l are 1, which corresponds to a bell-shaped orbital.
Therefore, the second quantum number for one of the electrons in the 4p energy sublevel of bromine is 1.

Answers
Answer:
Hydrogen bromide, anhydrous appears as a colorless gas with a pungent irritating odor. Corrosive. Heavier than air. Prolonged exposure to fire or intense heat may result in the violent rupture and rocketing of the container. Long-term exposure to low concentrations or short-term exposure to high concentrations can result in adverse health effects from inhalation. Used to make other chemicals and as a catalyst in the manufacture of chemicals. Rate of onset: Immediate Persistence: Minutes to hours Odor threshold: 2 ppm Source/use/other hazard: Chemical manufacturing industry; very corrosive.

(NEED HELP IMMEDIATELY) In a gene, which base sequence codes for two amino acids?
1. CTAA
2. AG
3. GAGCTC
4. GAA
Answers
Answer:
[tex]\boxed {\boxed {\sf 3. \ GAGCTC}}[/tex]
Explanation:
Amino acids are the monomers or building blocks of protein. Proteins are created during protein synthesis according to the genetic information or DNA in an organism.
The DNA is translated to messenger RNA in the nucleus. It travels to the ribosome. There, the mRNA is "read off" in threes. Three nucleotides make up a codon. Transfer RNA with the corresponding anticodon and an amino acid attaches to the codon and a chain of amino acid forms.
If 3 nucleotides make 1 codon which makes 1 amino acid, then we need double that or 6 nucleotides to make 2 amino acids.
The only answer choice with 6 nucleotides is Choice 3: GAGCTC

I hope this answer helps you out. Brainliest would be appreciated. Have a good day/night :).Al wonders if adding salt to water will affect how long it takes the water to
freeze. Al thinks that salt water will freeze more quickly than fresh water.
He decides to check his hypothesis by conducting an experiment. Al takes
two ice trays and fills one with distilled water and the other with distilled
water that has two tablespoons of salt added. He makes sure he puts
exactly the same amount of water in each ice tray. Al takes the trays and
puts them side by side in the freezer. Al checks the ice trays every 10
minutes to see if the water in each tray has begun to freeze. Al finds that
after 20 minutes the water in the ice tray without the salt has started to
form ice, while the ice tray with the salt water is still completely liquid.

Answers
The hypothesis is that salt water freezes faster than fresh water.
The dependent variable is time taken for ice to appear.
The independent variable is presence or absence of salt
The constants are the amount of water in each tray, freezing conditions and length of time of exposure to freezing condition.
The control group is the tray to which salt was not added
The experimental group is the tray to which salt was added
The presence of solutes in a solution causes the freezing point depression.
A solution is made up of a solute and a solvent. In the presence of a solute, the freezing point of a pure solvent is decreased. This is because freezing point is a colligative property.
Colligative properties depend on the amount of solute present.
Hence, the pure water freezes faster (ice begin to appear earlier) than the salt water.
The hypothesis put forward in this experiment was found to be invalid by the experiment.
