Given Data:
P₁ = 122 atm
P₂ = 112 atm
V₁ = 113 L
V₂ = ?
Solution:
Let suppose the gas is acting ideally. According to Ideal gas equation, keeping the temperature constant,
P₁ V₁ = P₂ V₂
Solving for V₂,
V₂ = P₁ V₁ / P₂
Putting Values,
V₂ = (122 atm × 113 L) ÷ 112 atm
V₂ = 113 L
Converting Volume to Moles,
As,
22.4 L is occupied by = 1 mole of He gas
So,
113 L will occupy = X moles of He gas
Solving for X,
X = (113 L × 1 mole) ÷ 22.4 L
X = 5.04 Moles of He
Answer:
A star is made up of burning gases, while a comet is made up of ice, gases, rocks, and dust.
Explanation:
Answer:
2, 8, 8
Explanation:
The first electron shell always has 2 electrons when it is complete. The second electron shell and 3rd shell can hold 8 when completed.
Answer:
(C) Only particular quantized energies are given off by excited electrons in the form of light.
Explanation:
Atomic emission spectra often have gaps that help to create the color lines.
These gaps occur as a result of heat energy absorbed by electrons in the atoms, making them to be excited and allow them to jump into higher energy levels by emitting only particular quantized energies in the form of light.
Therefore, the correct option is "C"
(C) Only particular quantized energies are given off by excited electrons in the form of light.
