Explanation:
probably because, X rays are used to ionise the gas molecules, which is loss of electrons, these electrons are absorbed by oil drops
Answer is: 12 <span>moles of water will be produced.
</span>Balanced chemical reaction: N₂H₄ + O₂ → N₂ + 2H₂O.
n(N₂H₄) = 6 mol.
From balanced chemical reaction: n(N₂H₄) : n(H₂O) = 1 : 2.
n(H₂O) = 2 · n(N₂H₄).
n(H₂O) = 2 · 6 mol.
n(H₂O) = 12 mol.
n - amount of substance.
Density = mass / volume
1.5 = m / 50.0
m = 1.5 x 50.0
m = 75 g
hope this helps!
