The H2 produced in a chemical reaction is collected through water in a eudiometer. The pressure (kPa) of the H2 gas is 98.89 kPa
The total pressure in a chemical reaction is the total sum of the partial pressure and the vapor pressure of the chemical substances taking place in the chemical reaction.
- Total pressure = partial pressure of H₂ gas + vapor pressure of H₂O
∴
The vapor pressure of H₂ gas = Total pressure in the eudiometer - partial pressure of H₂O
Given that:
- The total pressure in the eudiometer = 101.3 kPa
- The partial pressure of H₂O = 2.41 kPa
The vapor pressure of H₂ gas = 101.3 kPa - 2.41 kPa
The vapor pressure of H₂ gas = (101.3 - 2.41) kPa
The vapor pressure of H₂ = 98.89 kPa
Therefore, we can conclude that the vapor pressure of H₂ is 98.89 kPa.

Answer:
I think this would be iron
Explanation:
The two substances have different densities. Density can be affected by the temperature of a substance. Since they have to same volume but weigh differently, they have different densities. Remember, density = mass/volume
