Answer:
One electron per single hydrogen atom.
Explanation:
Hello!
In this case, given the reaction:
![H_2+O_2\rightarrow H_2O](https://tex.z-dn.net/?f=H_2%2BO_2%5Crightarrow%20H_2O)
Whereas we can identify the following half-reaction for hydrogen:
![H_2^0\rightarrow H_2^+](https://tex.z-dn.net/?f=H_2%5E0%5Crightarrow%20H_2%5E%2B)
Whereas we see that each single hydrogen atom gains one electron in order to go from 0 to +1, which is also related to an oxidation half-reaction.
Best regards!
Answer:
1 oxygen
Explanation:
cause H2O= two hydrogen + one oxyge
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 =
![\sqrt{M2 / M1}](https://tex.z-dn.net/?f=%20%5Csqrt%7BM2%20%2F%20M1%7D%20)
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 =
![\sqrt{32 / 4}](https://tex.z-dn.net/?f=%20%5Csqrt%7B32%20%2F%204%7D%20)
r₁ / r₂ =
![\sqrt{8}](https://tex.z-dn.net/?f=%20%5Csqrt%7B8%7D%20)
r₁ / r₂ =
2.82
Result:
Helium gas effuses
2.82 times faster than Oxygen gas.
