How much energy is released per Kg of Dilithium formed? Mass of one atom of 6 Li is 6.015121 amu. Do not know where to start.
When ethane (C2H6) reacts with chlorine (Cl2) the main product is C2H5Cl; but other products containing Cl (chlorine), such as C2H4Cl2, are also obtained in small quantities. The formation of these other products reduces the yield of C2H5Cl. In a ..
