Answer:
C. Energy can change one form to another
Explanation:
There are many different types (forms) of energy
Answer:
34 g
Explanation:
Let's consider the following balanced equation.
N₂ + 3 H₂ → 2 NH₃
The theoretical mass ratio of N₂ to H₂ is 28g N₂ : 6g H₂ = 4.6g N₂ : 1g H₂.
The experimental mass ratio of N₂ to H₂ is 100g N₂ : 6g H₂ = 16.6g N₂ : 1g H₂.
As we can see, hydrogen is the limiting reactant.
According to the task, we 6 g of H₂ react completely, 34 g of ammonia are produced.
Hey There!
ideal gas law :
PV = nRT
P = nRT/V
P = (1*0.082)(18+273)/(0.5) = 47.724 atm
For VDW :
(P + a(n/V)²)(V - nB) = nRT
P = nRT/(V - nB) - a(n/V)²
P = 1*0.082*(18+273) / (0.5-1*0.03219) - 1.345*( 1/0.5 )² = 45.62
P = 45.62 atm
Pdif = P2-P1 = 47.724 - 45.62 = 2.104 atm
