changing the told would mess up the amount a daylight/nighttime because they’d be at a different angle from the sun
volume of H₂O = 7.2 L
Explanation:
The combustion reaction of methane (CH₄):
CH₄ + 2 O₂ → CO₂ + 2 H₂O
Now we calculate the number of moles of methane using the following formula:
number of moles = volume / 22.4 (L/mole)
number of moles of CH₄ = 3.6 / 22.4
number of moles of CH₄ = 0.16 moles
Taking in account the chemical reaction, we devise the following reasoning:
if 1 mole of CH₄ produce 2 moles of H₂O
then 0.16 moles of CH₄ produce X moles of H₂O
X = (0.16 × 2) / 1 = 0.32 moles of H₂O
And now we can calculate the volume of water (H₂O) produced by the reaction:
number of moles = volume / 22.4 (L/mole)
volume = number of moles × 22.4 (L/mole)
volume of H₂O = 0.32 × 22.4
volume of H₂O = 7.2 L

In an atom, electrons travel outside the nucleus.
c. travel outside the nucleus.
Answer:
16.84 g
Explanation:
Assuming that the ethanol is free of water
the number of moles of ethanol to generate 500 KJ = 500 / 1368 = 0.3655 mol
molar mass of ethanol = 46.07 g/mol
mass of ethanol needed = 46.07 × 0.3655 = 16.84 g
Alkalines form this. (If that is what your ? is asking )
