Answer:
0.89 atm is the pressure of the hydrogen gas
Explanation:
We can use the molar fractions to solve this
Sum of molar fractions (hydrogen + water vapor) = 1
Molar fraction = Pressure gas / Total pressure
Molar fraction water vapor = 0.13 atm/1.02 atm = 0.127
1 - 0.127 = 0.873 (Molar fraction H2)
0.873 = Pressure H2 / Total pressure
0.873 = Pressure H2 / 1.02 atm
0.873 . 1.02atm = 0.89 atm

Answer: 15.7 liters
Explanation: reaction is 2H2 + O2. -> 2H2O
Because all substance still are gases, volumes in
STP conditions are proportional to amount of moles.
Amount of water is same as Hydrogen. Also volume is same.
Zinc is oxidized because it starts as a metal with an oxidation state of zero and ends up as an atom bound to oxygen. Oxygen has two bonds, so the oxidation state of Zinc would be 2. The Mercury is therefore reduced because it undergoes the opposite process. This is a REDOX reaction, and the two half-reactions are:
Zn -> Zn(+2) + 2e(-)
Hg(+2) + 2e(-) -> Hg
The answer to your question is C. I hope that this is the answer that you were looking for and it has helped you.
