That is an abbreviation for a kilojoules, a metric measure of energy.
kJ (kilo Joule) is a derived unit of energy; 1 kJ = 1 000 J = 0,238 845 9 kcal.
Joule (J) is the official unit for energy in SI.
KJ is the symbol of kilojoule.
According to the old Nuffield Chemistry Teachers' Guide based on class results the value is about +70 kJ mol-1.
14 KJ stamped on a necklace means it is 14 karat gold. This number signifies purity of gold, a top standard in jewelry.
The "I" in chemistry probably refers to the element iodine.
Do you mean chemistry
-18 kj/mol
My Chemistry textbook has it listed as -81 kJ/mol and chemicool.com has it as -78 kJ/mol.
This is my QustionListed below are ionization energies for removing successive electrons from various atoms of the third period. Which of the following lists corresponds to the ionization energies for phosphorus?a. 496 kJ, 4,560 kJ (I.E. for the first two electrons)b. 738 kJ, 1,450 kJ, 7,730 kJ (I.E. for the first three electrons)c. 578 kJ, 1,820 kJ, 2,750 kJ, 11,600 kJ (I.E. for the first four electrons)d. 786 kJ, 1,580 kJ, 3,230 kJ, 4,360 kJ, 16,100 kJ (I.E. for the first five electrons)e. 1,012 kJ, 1,900 kJ, 2,910 kJ, 4,960 kJ, 6,270 kJ (I.E. for the first five electrons)

From an experiment I did in my chemistry lab, I got a value of 52.0 kJ. But I have no idea what the "true" Ea is.
945.33 kJ/mol
