Ten name if this compound is Potassium Oxide
Adding a catalyst as this would speed up the reaction and the rest would slow it down
Anything less that 7, would be a base.
So for D you have to find energy right
from c you get wavelength Lambda
so on D use this
E = Hc / lambda
c is given 1.5 x 10 ^20
h = 6.624 x 10^-34
and then you get answer for energy
What do you mean by this?
