Answer:
0, 1, 2, 3
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
- Principal Energy Level <em>n</em> (1 to ∞)
- Angular Momentum ℓ (n - 1)
- Magnetic mℓ
- Electron Spin ms
Explanation:
<u>Step 1: Define quantum number</u>
Principal Energy Level <em>n</em> = 4
<u>Step 2: Define ℓ</u>
ℓ is the Angular Momentum. Its values start at 0, 1, 2, 3...
It is the Principal Energy Level <em>n</em> minus 1 (n - 1).
<u>Step 3: Find</u>
n = 4
ℓ = 4 - 1 = 3
Therefore, out angular momentum values can be 0, 1, 2, 3. These correlate to s, p, d, f sublevels.
Answer:
The correct answer is b. 2Mg(s) + O2(g) + 2H2O(l) → 2Mg2+(aq) + 4OH-(aq)
Explanation:
The Mg is oxidized to Mg 2+, and the oxygen (02) is reduced.
Based on my experience in working in the laboratory, the best answer is a buret. It is the standard tool used in a titration method. Also, it is the best glassware because you can read directly the amount of volume added to a solution. Hope this helps.
It is called a proton I hope this helps
The answer is A sorry if I didn’t explain but it’s A
