Describe why shielding is more effective by electrons in a shell of lower principle quantum number than by electrons having the similar principle quantum number.
If change in energy (ΔE) = 3x 10 -8 j, h= 6.64x 10 -34 j-s and c= 3x 10 8 m/s then wavelength of the light is: (1) 6.36x 10 3 Å (2) 6.36x 10 5 Å
Overall reaction is H+ + I- +H2O2 -> H2O +HIO. If you wanted to increase the rate of the overall reaction, would it be better to increase the concentration of H+ or I-. Why?
