Answer:
Ba: 1s² 2s²2p⁶ 3s²3p⁶ 4s²3d¹⁰4p⁶ 5s²4d¹⁰5p⁶ 6s²
Step-by-step explanation:
Step 1. Locate barium in the Periodic Table.
It's in Period 6, Group 2: Element 56 (highlighted blue in the Periodic Table below).
Step 2. Add 54 electrons to the energy levels
You add then in the order shown in the diagram below.
The complete electron configuration is:
Ba: 1s² 2s²2p⁶ 3s²3p⁶ 4s²3d¹⁰4p⁶ 5s²4d¹⁰5p⁶ 6s²
n = 2 + 8 + 8 + 18 + 18 + 2 = 56

Answer:
Interphase: the resting phase between successive mitotic divisions of a cell, or between the first and second divisions of meiosis.
Mitosis: Mitosis is a process where a single cell divides into two identical daughter cells (cell division). The major purpose of mitosis is for growth and to replace worn out cells.
Cytokinesis: Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells. ... Mitosis and each of the two meiotic divisions result in two separate nuclei contained within a single cell.

I learned about this and it was pretty confusing. But once you start learning this more, you'll definitely get it! :D
Answer: Alcohol and water in the solution have different boiling points.
Explanation: The substance that has a lower boiling point evaporates faster. For this case alcohol has a lower boiling point than water so it evaporates in a faster rate. This process of distillation separates alcohol and water in a solution.
