The scientist that developed the equation of wave mechanics is <span>Erwin Schrodinger that combined the works of Bohr and de Broglie. The electron
was a three dimensional wave circling the nucleus in a whole number of wavelengths
allowing the waveform to repeat itself as a stable standing wave (it can absorb
energy form a nearby source which is oscillating at a proper frequency)
representing the energy levels of Bohr model. He also said that Broglie’s model
was correct about the matter waves and the electrons are located in the atomic
space according to standing wave frequencies.</span>
Answer:
P(total) = 978 mmHg
Explanation:
Given data:
Total pressure of gas = ?
Partial pressure of O₂ gas = 200 mmHg
Partial pressure of N₂ gas = 350 mmHg
Partial pressure of He gas = 428 mmHg
Solution:
According to Dalton law of partial pressure,
The total pressure inside container is equal to the sum of partial pressures of individual gases present in container.
Mathematical expression:
P(total) = P₁ + P₂ + P₃+ ............+Pₙ
P(total) = P(O₂) + P(N₂) + P(He)
P(total) = 200 mmHg + 350 mmHg + 428 mmHg
P(total) = 978 mmHg
Friction occurs when two surfaces come into contact. Excess friction hinders movement, and it wastes energy. Friction refers to a force that opposes motion. It is important because it is applied in almost all life processes.
