valentinak56 [21]3 years ago
4 0

Answer:

Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties. Dalton based his theory on the law of conservation of mass and the law of constant composition. ... Parts of the theory had to be modified based on the existence of subatomic particles and isotopes.

The electron in a hydrogen atom can undergo a transition from n = 4 to n = 3, emitting a photon with energy 1.06 × 10 –19J. Use
konstantin123 [22]

Answer:

Wavelength (λ) = 1.875 × 10⁻⁶ m

Explanation:

Given:

Energy (e) =  1.06 × 10⁻¹⁹ J

Find:

Wavelength (λ) = ?

Computation:

e = hc / λ

λ = hc / e

where c = 3 × 10⁸

Planck's constant (h) = 6.625 × 10⁻³⁴

So,

Wavelength (λ) = (6.625 × 10⁻³⁴)(3 × 10⁸) / (1.06 × 10⁻¹⁹)

1. Wavelength (λ) = 1.875 × 10⁻⁶ m

2. Given n = 4 to n = 3 both are integer not fraction so, electron is quantize

why is it necessary to adjust the height of the graduated cylinder when measuring the volume of co2 (g) produced? group of answe
Elanso [62]

3. The height of the graduated cylinder when measuring the volume of co2 (g) produced is adjusted to equalize the pressure in the graduated cylinder with the atmospheric pressure.

We discovered that when the water level within the graduated cylinder is higher than the water level outside, the gases inside the graduated cylinder have a lower pressure than the atmospheric pressure. It would then be possible to equalize pressure by changing the graduated cylinder's water level to match the water level outside.

Therefore last option or 3rd option is the correct choice.
