WebThe effects of water vapor ionization on the nonlinear propagation of femtosecond laser pulses with a 248 nm wavelength are numerically investigated in this paper. It is found that ionization of H2O molecules plays a significant role in air ionization, which seriously affects the dynamic and energy deposition of filamentation. The propagation of femtosecond … WebJan 1, 2010 · Ionisation Energies. The Ionisation Energy ( IE) of an element is the amount of energy required to remove one mole of electrons from one mole of gaseous atoms of an element to form one mole of gaseous ions. Ionisation energies are measured under standard conditions which are 298 K and 101 kPa. The units of IE are kilojoules per mole …
WebAnswer 1- The total energy to bring about the change. = IE1 + IE2 +IE3. = 578 + 1817 + 2745. = 5140. Now, number of mole present in 0.720 gm of Al=. 0.720/27 = 0.03mole. = 3 × mole. Hence, 3 × mole of Al will require 5140 × = 51.40 kJ. Question 2- In both potassium and copper, the removal of an outer electron has to take place from the 4s ...
