Answer: The partial pressure of the hydrogen gas is 93.9 kiloPascals.
Explanation:
The partial pressure of the water vapors =
The partial pressure of the hydrogen gas =
The pressure measured in the collecting bottle =
While collecting the hydrogen gas in a collecting bottle with amount of water vapors also get introduced. The total pressure in the collecting bottle will be due to partial pressures of the water vapors and hydrogen.
The partial pressure of the hydrogen gas is 93.9 kiloPascals.
The properties like shape, structure, etc. that define the appearance of matter is said to be its physical properties whereas the properties like oxidation, toxicity, etc. that defines how a new product is formed from the other substances is said to be its chemical properties.
It is given that a 2.0 L volume of hydrogen gas is combined with 1.0 L of oxygen gas to produce 2.0 L of water vapor. The chemical reaction is as:
Since, the reaction between hydrogen and oxygen results in the formation of complete new product, water. So, oxygen will undergo a chemical change.
