Answer: 78.3 torr
Explanation:
According to Raoult's law, the vapor pressure of a component at a given temperature is equal to the mole fraction of that component multiplied by the vapor pressure of that component in the pure state.
and
where, x = mole fraction
in solution
= pressure in the pure state
According to Dalton's law, the total pressure is the sum of individual pressures.
moles of ethanol=
moles of methanol=
Total moles = moles of ethanol + moles of methanol = 1.7 +3.0 = 4.7
,
,
Thus the vapor pressure of a mixture of 80 g of ethanol and 97 g of methanol at 293 K is 78.3 torr.

Answer: The bubbles produced are most likely due to oxygen.
Explanation:
Photosynthesis is a phenomenon in which green plants containing chlorophyll use sunlight as a source of energy to convert carbon dioxide and water to form glucose and oxygen.
The balanced chemical reaction for photosynthesis is:
