Answer: -
H₂ will diffuse the fastest.
Explanation: -
According to Graham's Law of Diffusion
The rate of diffusion is inversely proportional to the square root of it's density or molar mass. So the lower the molar mass faster the rate of diffusion.
Molar mass of Ne = 20 g / mol
Molar mass of CH₄ = 12 x 1 + 1 x 4 = 16 g /mol
Molar mass of Ar = 40g / mol
Molar mass of H₂ = 1 x 2 = 2 g / mol
Thus H₂ will diffuse the fastest.
Answer:
Lead I think is one I'm not completely sure but I know they're similar in some ways
Answer:
22.29%
Explanation:
Percent yield = experimental yield / theoretical yield * 100
= 12.89 / 57.82 * 100 = 22.29%
A. The kinetic energy of gas particles is higher in hot food than in cold food.
Explanation:
The smell of a hot food moves faster than the smell of a cold food because the kinetic energy of gas particles is higher in hot food than in cold food.
Let us establish that the smell of the food perceived are gases from the food.
- Both hot food and cold food emits these gases that tinkers our olfactory nerves.
- Hot food produces a hot gas.
- The higher the temperature the more kinetic energy it possess.
- This makes the gases more dispersed and it spreads faster.
- The cold food produces gas at a lower kinetic energy.

The reaction between C2H6 and
Cl2 by addition is C2H4Cl2 or dichloroethane. It must be under the presence of
sunlight because halogen such as chlorine cannot easily react with the sigma
bond of alkane such as ethane.
