Answer:
The mass is
Explanation:
From the question we are told that
The current supplied is
The time taken is t = 37.0 sec
Generally the charge been deposited on the cathode is mathematically represented as
Substituting values
Generally 1 mole of the lead deposited contains
Then would contain how many moles
Not let say x is the number of moles deposited then
Using this mathematical relation
From the the question we are told that lead is been oxidized to lead 2 oxide which implies that the two electron would be accepted by the lead cation
Hence the number of moles that would be deposited at the cathode is
Now the molar mass of lead is constant with a value
Generally mass is mathematically represented as
For lead
Substituting values
The forward and reverse reactions proceed at the same rate once at equilibrium.
Answer:
answer is A. Alkaline metal lose two electrons not gain
The answer is d
the image shows the moles of gas increasing as well as volume increasing
Air is a mixture and table salt is a compound. Air is composed of different types of elements that can be separated whereas table salt is more uniform and consists of Na (sodium) and Cl (chloride) to form the compound sodium chloride.
