Interpretation: Purpose of additional orbitals in hydrogen even if it has 1 electron is to be explained.
Concept introduction: 3-D space around nucleus in which probability of finding an electron of particular energy is maximum, is called orbital. Quantum numbers are group of 4 numbers which tell everything about electron present in an atom. Principal quantum numbers indicates principal energy level in which electron in present. It is denoted by

Answer to Problem 29A
Additional orbital are excited states of hydrogen atom which are occupied only when some discrete energy is given to it.
Explanation of Solution
Orbital is maximum probability space for electrons where it can be found. When hydrogen in ground state its electron is present in the lowest energy shell that is
So on excitation of hydrogen atom electron can occupy
Additional orbital are excited states of hydrogen atom which are occupied only when some discrete energy is given to it.

- 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 ["", "", "", "", ""] . When you really weren't paying attention and reached the second equivalence point of Na2CO3, the color isarrow_forwardThe following reaction is run in which the initial conditions include only methane (CH4) at a concentration of0.115 M.
