Answer:
b) the gases will mix closer to the end that holds the heavier gas.
Explanation:
The question is based on the Graham's law of diffusion.
- According to Graham's law of effusion, the rate of effusion of gases is dependent on the density of the gases. Such that the rate of effusion a gas is inversely proportional to the square root of its density.
- Therefore, a lighter gas effuses faster compared to a heavier gas.
- In this case, the gases will mix closer to the end that holds the heavier gas, because the lighter gas will effuse faster and cover a longer distance compared to the heavier gas.
- For instance , if we take two gases ammonia (NH4) and Chlorine (Cl2), if they were allowed to effuse from opposite ends of a long tube, then NH4 would effuse faster since it is lighter than chlorine. Consequently, the two would mix near the end that holds chlorine gas.
The correct answer Thomson's
2,16·10²⁴ = 21,6·10²³
---------------------------
6,02·10²³ atoms ------ 1 mole of Ag
21,6·10²³ atoms ------ X
X = 21,6·10²³/<span>6,02·10²³
<u>X = 3,588</u> moles of silver
