1. You could drain off the oil as a supernatant, since oil is less dense than water.
2. You could attempt to evaporate the water since they have different boiling points (212 vs 572 F), and then condense it in a separate container using a distillation unit.
Answer:
8 gram
Explanation:
in case of NaOH, normality=molarity
so normality=molarity×acidity or basicity(in case of NaOH it's 1)
then
weight of NaOH required = volume in ml × equivalent weight × normality / 1000
so
1000× 40× 0.2/1000
=8 gram
The answer is B ,synthesis :)
Answer:
27 moles of H₂
Explanation:
Equation of reaction:
N₂ + 3H₂ → 2NH₃
From the equation of reaction,
3 moles of H₂ is required to produce 2 moles of NH₃
3 moles H₂ = 2 moles of NH₃
X moles of H₂ = 18 moles of NH₃
X = (3 * 18) / 2
X = 27 moles of H₂
27 moles of H₂ is required to produce 18 moles of NH₃
