Answer:
30 moles
Explanation:
From the equation it is a one - to - one reaction
Answer:
The volume will be "2.95 L".
Explanation:
Given:
n = 0.104
p = 0.91 atm
T = 314 K
Now,
The Volume (V) will be:
= 
By putting the values, we get
= 
= 
= 
Answer : The limiting reagent is 
Solution : Given,
Moles of methane = 2.8 moles
Moles of
= 5 moles
Now we have to calculate the limiting and excess reagent.
The balanced chemical reaction is,

From the balanced reaction we conclude that
As, 2 mole of
react with 1 mole of 
So, 5 moles of
react with
moles of 
From this we conclude that,
is an excess reagent because the given moles are greater than the required moles and
is a limiting reagent and it limits the formation of product.
Hence, the limiting reagent is 
The crust of the Earth is thickest beneath the continents.
Ideal Gas Law
Given: P1= 1.25 atm P2= 95 atm
V1= 2.50 L
Unknown: V2=?
Formula: V=nRT/P; n = RT / PV
Solution: n = (0.0821 L x atm / K x mol) (285K) / (1.25 atm) ( 2.50L)
= 23.40 / 3.125
Answer: n = 7.49 moles of gas the balloon holds
