There are 2 Na and 2 NO3 on the left side so there must be 2 NaNO3 on the right side. !st Law of thermodynamics: Mass cannot be created nor destroyed .
I believe you can simply add more cells in series to get a higher voltage. Not 100% sure on that.
A) it keeps the the top layer of the geosphere cool
Answer:
The rate of reaction of a zero-order reaction is 0.0020 mol/L.
Explanation:
The rate expression of the zero order kinetic are :
[A]= initial concentration of reactant
k = rate constant
R = rate of reaction
We have :
Rate constant of the reaction , k = 0.0020 mol/L s
R = 0.0020 mol/L s
The rate of reaction of a zero-order reaction is 0.0020 mol/L.
