Answer:
4 atmospheric pressure is needed to get a volume of 25 litres
Answer:
Dehydration Reaction
Explanation:
Alcohols can be converted into Alkenes using catalytic amounts of acids as a catalysts.
The water molecule is removed hence, it is called as dehydration reaction.
The reaction is attached.
Answer:
86.3 g of N₂ are in the room
Explanation:
First of all we need the pressure from the N₂ in order to apply the Ideal Gases Law and determine, the moles of gas that are contained in the room.
We apply the mole fraction:
Mole fraction N₂ = N₂ pressure / Total pressure
0.78 . 1 atm = 0.78 atm → N₂ pressure
Room temperature → 20°C → 20°C + 273 = 293K
Let's replace data: 0.78 atm . 95L = n . 0.082 . 293K
(0.78 atm . 95L) /0.082 . 293K = n
3.08 moles = n
Let's convert the moles to mass → 3.08 mol . 28g /1mol = 86.3 g
