Answer:
The answer is 434nm
Explanation:
The Rydberg equation is an empirical relationship expressed by Balmer and Rydberg which is stated as:
1/λ = 
.............................. (1)
where λ is the wavelength, 
is the Rydberg constant equal to 
, n is the transition level number, the subscript f and i are the final and initial levels respectively. Therefore for final transition n = 2 and for initial transition n = 5.
Making substitutions into equation (1), gives
1/λ = 
= 
= 
= 
= 2303700
∴ λ = 
Converting to nm, we have
λ = 
Therefore, the wavelength of the emitted photon is 434nm
Answer:
Ideal gas explains the property of gas that has no inter-molecular attractions irrespective of temperature and pressure.
<u>Explanation:</u>
- Ideal gases assumes that the gases would experience no inter-molecular attraction and collision with other gases.
- These gases are perfectly exhibiting elastic collision in nature.
- The particle of gases moves slowly at lower temperature and the gases would become close when they exhibit high pressure.
- The "closeness of the gas-particle" and "low-speed characteristics" are the important observations noted.
- The inter-molecular forces deviate the property of gases from ideal gas behavior.
For average speed, we divide the total distance covered by the total time taken.
After doing that, you will see that Jane has the lowest average speed.
Answer:
<h2>
2Al +
3CuO ==>
3Cu + Al2O3</h2>
Explanation:
So let's break this chemical equation down into 2 parts - Reactants and Products
Reactants = Al + CuO
Products = Cu + Al2O3
So the Chemical Reaction will be
Al + CuO ==> Cu + Al2O3
So the balanced equation will be,
2Al + 3CuO ==> 3Cu + Al2O3
