Interpretation: The given concept of an orbital shown is to be determined.
Concept introduction:
Orbital is the three-dimensional region in an atom where the electron finding probability is maximum.

Answer to Problem 23A
The orbitals are that space in an atom where the electron finding probability is highest.
Explanation of Solution
Orbital is described as the hydrogen electron probability map. As going away from the nucleus, the electron finding probability is decreased but never becomes exactly zero. As an orbital does not have a defined size, arbitrarily its size is defined as a sphere that contains 90% of the total electron probability.
The first Principal energy level of the hydrogen atom consisting of only one sub-level, which contains the 1s orbital, and the second principal energy level contain two sub-levels, one of which contains the 2s orbital and another one contains the 2p orbitals.

- For each scenario below, select the color of the solution using the indicator thymol blue during the titration. When you first add indicator to your Na2CO3solution, the solution is basic (pH ~10), and the color is ["", "", "", "", ""] . At the equivalence point for the titration, the moles of added HCl are equal to the moles of Na2CO3. One drop (or less!) past this is called the endpoint. The added HCl begins to titrate the thymol blue indicator itself. At the endpoint, the indicator color is ["", "", "", "", ""] . When you weren't paying attention and added too much HCl (~12 mL extra), the color is ["", "", "", "", ""] .
