A reaction is first order. If the initial reactant concentration is 0.0200 M, and 25.0 days later the concentration is 6.25 x 10-4 M, then its half-life is:
it has less tightly bound electrons, is able to lose electron easily as compare to metal B at it has 4 unpaired electron in 3d sub-shell.
Answer:
The electric force is conservative.
Since
ΔK = −ΔU,
Kf − Ki =Ui −Uf.
We have,
Kf = 0
Ui = 0.
Thus Ki =Uf.
<u>so ,at 10 fm Uf = (2×10)−12 J.</u>
