shes your teacher duh, they have magic spells that give em the answer
According to
Graham's Law of Diffusion,"the rates of diffusion of two gases are inversely proportional to the square root of their Molar masses or Densities at the same pressure and temperature".
r₁ / r₂ =
Where,
r₁ = Rate of Helium
r₂ = Rate of Oxygen
M₂ = Molar mass of Oxygen = 32 g/mol
M₁ = Molar mass of Fluorine = 4 g/mol
Putting values,
r₁ / r₂ =
r₁ / r₂ =
r₁ / r₂ =
2.82
Result:
Helium gas effuses
2.82 times faster than Oxygen gas.
Answer:
The magnets will push away from each other.
Answer : The volume of water produced by this reaction would be, 4.75 liters.
Explanation : Given,
Volume of HCl gas = 9.5 L
The balanced chemical reaction will be:
As we know that at STP, 1 mole of gas occupy 22.4 L volume of gas.
By the stoichiometry we can say that:
As, 4 liter volume of HCl gas react to give 2 liter volume of water
So, 9.5 liter volume of HCl gas react to give volume of water
Therefore, the volume of water produced by this reaction would be, 4.75 liters.
