No because ethanol is nonelectrolyte
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.
It looks like a bunch of squares. Lolb
Answer:
72g of H2O.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
2H2 + O2 —>2H2O
Next, we'll determine the mass of O2 that reacted and the mass of H2O produced from the balanced equation.
This is illustrated below:
Molar Mass of O2 = 16x2 = 32g/mol
Molar Mass of H2O = (2x1) + 16 = 18g/mol
Mass of H2O from the balanced equation = 2 x 18 = 36g
Summary:
From the balanced equation above,
32g of O2 reacted to produce 36g of H2O.
Now, we can obtain the mass of H2O produced when 64g of O2 react as follow:
From the balanced equation above,
32g of O2 reacted to produce 36g of H2O.
Therefore, 64g of O2 will react to produce = (64 x 36)/32 = 72g of H2O.
From the calculations made above, 72g of H2O is produced from the reaction.
