It can be controlled, and also contained, the statement is false
Answer:
Longitudinal wave
Explanation:
This is a longitudinal wave. Air is known to travel through a longitudinal wave. A wave is a disturbance that goes through a medium. As this musician blows into his trumpet, a vibration is formed, which moves in the direction as where the wave is coming from. Air moves in parallel direction as the wave
3H₂ + N₂ = 2NH₃
V(H₂)/3 = V(NH₃)/2
V(NH₃)=2V(H₂)/3
V(NH₃)=2*4.50/3=3.00 L
3.00 L
Answer:
Option C. 88 KJ
Explanation:
The activation energy (Ea) is the minimum energy that reactant must overcome in order for them to proceed to product.
In an energy profile diagram, the activation energy (Ea) is obtained by calculating the difference between the energy of the activation complex (i.e peak) and the energy of the reactant.
With the above information, we shall determine the activation energy (Ea) of the reaction above as follow:
Activation complex = 268.74 KJ
Energy of reactant = 180.74 KJ
Activation energy (Ea) =?
Activation energy = Activation complex – Energy of reactant
Activation energy = 268.74 – 180.74
Activation energy = 88 KJ
Therefore, the activation energy (Ea) of the reaction is 88 KJ
The answer is A because it cant pollute the atmosphere because its vapor from water that is being thrown out and it is reusable / the chemical reaction last longer
