When a chemist collects hydrogen gas over water, she ends up with a mixture of hydrogen and water vapor in her collecting bottle
1 answer:
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.

Answer: 0.055 moles of are produced by the reaction of 0.055 mol of ammonium perchlorate.
Explanation:
The balanced chemical reaction for decomposition of ammonium perchlorate is:
According to stoichiometry :
2 moles of produce = 2 moles of
Thus 0.055 moles of will produce =
of
Thus 0.055 moles of are produced by the reaction of 0.055mol of ammonium perchlorate.
