Answer:
The 2 beakers of water will have different boiling points because the boiling point of water is a physical property and the property is independent of the amount of water.
Explanation:
Got 100 on my test
N₂ + 3H₂ → 2NH₃
Based on the reaction, Mole ratio of H₂ to N₂ is 3 : 1 [ 1N₂ + 3H₂ → 2NH₃]
∴ if moles of Hydrogen = 6.34 mol
then moles of nitogen = 6.34 mol ÷ 3
= 2.11 moles
∴ 2.11 moles (OPTION 2) of Nitrogen is needed to convert 6.34 moles of Hydrogen into ammonia.

Answer:
uhhh i do not know this but we are learning at my school i could give you the answer soon i you want
Explanation:
<span>10 g of hexane has a greater volume than 10 g of toluene.
volume of hexane = 15.27 mL
volume of toluene = 11.53 mL
First, look up the density of hexane and toluene.
hexane = 0.6548 g/mL
toluene = 0.867 g/mL
Since hexane has the lower density, the same mass of hexane will have a higher volume than the same mass of toluene. No need for you to actually calculate the volume for the first part of the question.
However, the 2nd part of the question does require you to calculate the volume. That is a simple matter of division.
volume of hexane = 10 g / 0.6548 g/mL = 15.27 mL
volume of toluene = 10 g / 0.867 g/mL = 11.53 mL</span>
