The intermediate energy level that the electron reached from the ground state is; n= 3.
<h3>What are energy levels in an atom?</h3>
The fixed distances from an atom's nucleus where electrons may be found are referred to as energy levels (also known as electron shells). Higher energy electrons have greater energy as you move out from the nucleus.
A region of space within an energy level known as an orbital is where an electron is most likely to be found.
The formula to get the higher level is Rydberg's formula;
1/λ = R(1/n₁² - 1/n₂²)
where;
R is rydberg constant = 1.097 × 10⁷ m⁻¹
We want to find the intermediate level where wavelength = 1281 nm = 1281 × 10⁻⁹ m
Thus;
n₂ = √(1/0.1112)
n₂ ≈ 3

Answer:
The carbon footprint of one plastic bottle of mass 23.5 g is 34.390 g.
Explanation:
The carbon footprint of one plastic bottle can be estimated by simple rule of three. That is:
The carbon footprint of one plastic bottle of mass 23.5 g is 34.390 g.
Answer:
The new pressure is 1,135.67 torr
Explanation:
Boyle's law establishes the relationship between pressure and volume of a gas when the temperature is constant, establishing that the pressure of a gas in a closed container is inversely proportional to the volume of the container. Mathematically, this law says that the product of pressure and volume is constant:
P*V=k
Charles's law establishes the relationship between the temperature and the volume of a gas when the pressure is constant. This law states that the volume is directly proportional to the temperature of the gas. So, Charles's law says that the quotient that exists between the volume and the temperature will always have the same value:
Finally, Gay-Lussac's Law is a gas law that relates pressure and temperature at constant volume. This law says that the pressure of the gas is directly proportional to its temperature:
Combined law equation is the combination of three gas laws called Boyle's, Charlie's and Gay-Lusac's law:
Analyzing an initial state 1 and a final state 2, it is satisfied:
In this case:
- P1= 662 torr
- V1= 46.7 L
- T1= 266 K
- P2= ?
- V2= 35 L
- T2= 342 K
Replacing:
Solving:
P2= 1,135.67 torr
<u><em>The new pressure is 1,135.67 torr</em></u>
