90% of energy is lost. only 10% is left.
therefore the answer is B. 90%
Answer:
the pressure (torr) of theH₂ gas is 736.2 torr
Explanation:
Given that
The H₂ gas produced in a chemical reaction is collected through water in a eudiometer; during this process, the gas collected contains some droplets of water vapor along with these gas.
So; the total pressure in the eudiometer = Pressure in the H₂ gas - Pressure of the water vapor
Where;
= total pressure in the eudiometer = 760.0 torr
= Pressure in the H₂ gas = ???
= Pressure in the water vapor = 23.8 torr
Now:

= (- 23.8 + 760) torr
= 736.2 torr
Thus; the pressure (torr) of theH₂ gas is 736.2 torr
