An excited electron jumps back to its ground state in two steps. What will its emission spectrum look like?

A) one long line

B) one thick line

C) two distinct lines

D) a continuous patch

C. two distinct lines.

Explanation:

Emission spectral is the characteristics of energies involved. When an electron absorbs energy, it gets excited and jumps to a higher energy level that has a quantified energy value equal to that absorbed. On de-excitation, it drops back to a lower energy level or the ground state and emmit energy(ies) in the process in form of spectrum.

In the question given, the electron jumps back to its ground state in two steps. It initially drops from the excited state to a lower energy level and latter drops to its ground state. Thus, two distinct lines would be emitted.

c)red bank

explanation:

red bank is a borough in monmouth county, new jersey, incorporated in 1908 and located on the navesink river, the area's original transportation route to the ocean and other ports.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
