Answer:
Explanation:
From the question we are told that:
Frequency 
Generally the equation for Energy of an electromagnetic wave is mathematically given by
Where
h=Planck's constant
Therefore
Parents pass characteristics such as hair color, nose shape, and skin color to their offspring. Not all of the parents' characteristics will appear in the offspring, but the characteristics that are more likely to appear can be predicted.
A electrolytic* cell that electrolysis occurs
Ex. let say you wanted traces of graphene you would set up your usual electro-chemical exfoliation rig and the graphite you submerge would be your electrolytic cell.
Hopped this helped
The operating properly of a chemical plant would have to the same property of any chemicals but its in a plant form instead of test tubes it would have a stem and leaves and you could squeaz the plant and get it out of the plant
When dT = Kf * molality * i
= Kf*m*i
and when molality = (no of moles of solute) / Kg of solvent
= 2.5g /250g x 1 mol /85 g x1000g/kg
=0.1176 molal
and Kf for water = - 1.86 and dT = -0.255
by substitution
0.255 = 1.86* 0.1176 * i
∴ i = 1.166
when the degree of dissociation formula is: when n=2 and i = 1.166
a= i-1/n-1 = (1.166-1)/(2-1) = 0.359 by substitution by a and c(molality) in K formula
∴K = Ca^2/(1-a)
= (0.1176 * 0.359)^2 / (1-0.359)
= 2.8x10^-3
