Answer:
D
Explanation:
the H2O2 under go reduction to remove O2 and then forms water
Answer:
Partial pressure of Ne is 0.61 atm.
Explanation:
Mole fraction of a gas
in mixture = (no. of moles of the gas in mixture)/(total no. of moles of gases in mixture)
Here, total no. of moles of gases = (0.32 + 0.56) moles = 0.88 moles
So, mole fraction of Ne in mixture, 
Let's assume both He and Ne along with their mixture behaves ideally,
Hence, in accordance with Dalton's law of partial pressure-

Where,
and
are partial pressure of Ne and total pressure respectively.
So, 
So, partial pressure of Ne is 0.61 atm.
Heat is being applied to the liquid. The right amount of heat causes the liquid to evaporate and become water vapor or steam-gas.
