Combustion is the term used when something ignites
Neutralization is the term used when opposite pH acids and alkalis mix
Polymerization is the term used when monomers are chemically reacted to make polymers
Transmutation is the term used when an atom changes from one element to another
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.
