Because the size of atoms increase as you move down the periodic table.
Radio waves.
From lowest to highest it is radio wave, microwave, infrared, visible light, ultraviolet, x ray, and then gamma.
The equilibrium constant, Kc, can be determined knowing that the balanced chemical reaction is N2 + 3H2 = 2 NH3. At equilibrium, Kc is equal to (concentration of NH3)^2 / [(concentration of N2) x (concentration of H2)^3]. Using the given values, Kc is computed to be equal to 1.9977 x 10^-4.
We can use the following equation to calculate the concentration of diluted solution.
c1v1 = c2v2
where c1 is concentration and v1 is volume of stock solution, which is the more concentrated solution.
c2 is concentration and v2 is the volume of diluted solution.
substituting the values in the equation,
0.188 M x 25.0 mL = c2 x 150.0 mL
c2 = 0.0313 M
concentration of diluted solution is 0.0313 M
