The flames being emitted by the ions are as a result of ions 3. emitting energy as they return to lower energy levels.
When ions are heated:
As they move around, they expend some of that energy and lose it as a result thereby returning to lower energy levels. As that energy is lost, it comes across as light being emitted by the ions.
In conclusion, ions in the flame test emit light as they lose energy and return to a lower energy level.

Answer;
-Emit energy as they return to lower energy levels.
Explanation;
-A characteristic color of light is emitted by these ions in the flame when the electrons emit energy as they return to lower energy levels.
-The metal ions do absorb energy, and the electrons are boosted to higher energy levels, but they emit that energy as they fall to lower levels, and it is the photons of light they are emitting that can be seen.
Answer:
There are 1, 13 moles of chlorine gas.
Explanation:
We apply the formula of the ideal gases, we clear n (number of moles); we use the ideal gas constant R = 0.082 l atm / K mol:
PV= nRT ---> n= PV/RT
n= 0,98 atm x 35,5 L /0,082 l atm / K mol x 373 K
n= 1,137448506 mol
False
