Answer : Normally in any chemical reaction, if the enthalpy change i.e. ΔH is positive which means it is greater than zero then it can be called as an Endothermic Reaction.
Whereas, the system under study is absorbing heat that is produced during the reaction. So if ΔH is found to be positive then it can be called as endothermic reaction.
Density= mass/volume
volume=mass/density
volume= 40.0g/1.114g per mL
volume= 35.90664273 mL
volume = 35.9 mL

They don't share and both deal with only 1 electron.
Lithium gives away 1 electron.
F will receive that electron.
The chemical formula is LiF
Atomic mass / mass number / atomic weight
(all of which mean the same thing)
