Pretty sure A is the correct answer
Answer:
The pH of the lye in soap is 13.
Explanation:
Why can't elements be separated into smaller parts using chemical means? Too much energy is required, since you'd have to break them down into protons, neutrons, and electrons. You can get this much energy together with nuclear reactions, but not by chemical means.
Answer: B
Your answer would be ecosystem because ecosystem is all the living things in an area interacting with all of the abiotic parts of the environment.
You are given both the energy level, n = 4, and the subshell, l = 3 on which the electrons reside.
The subshell is given to you by the angular momentum quantum number, l which can take value that ranges from 0 to n − 1
l = 0 → the s-subshell
l = 1 → the p-subshell
l = 2 → the d-subshell
l = 3 → the f-subshell
<u>For n = 4 and l = 3, ml can be -3, -2, -1, 0, +2, +2, and +3. </u>
<u>Each of these can have 2 electrons (+1/2 and -1/2 spin) for a total of 14 electrons.</u>
