Answer:
5.34 moles of are required to produce 3.56 mol of
.
0.83 moles of water react with 2.5 moles of .
Explanation:
i)
Moles of we want to produce = 3.56 moles
According to reaction, 2 moles of are obtained from 3 moles of
Then 3.56 moles of will be obtained from :
of
5.34 moles of are required to produce 3.56 mol of
.
ii)
Moles of = 2.5 moles
According to reaction,3 moles of reacts with 1 mole of
,then 2.5 moles of
will react with :
of
0.83 moles of water react with 2.5 moles of .
Answer:
D) Boyle's Law
Explanation:
Boyle's law states that:
"For a fixed mass of an ideal gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume".
Mathematically, it can be written as
where
p is the pressure of the gas
V is its volume
This can also be written as
In this problem, we have a bag of potato chip which is placed on an airplane. When the plane reaches its cruising altitude, the pressure in the cabin is much lower than the pressure at sea level. As a result, also the pressure of the air inside the bag will also be lower (because the internal pressure tries to balance the external pressure).
According to Boyle's law, however, this means that the volume of the bag will increase: and at some point, the volume of the air inside the bag will be too big for the bag to "resist", and the bag will eventually explode.
