2Li(s) + 2HCL(aq) 2LiCl(aq) + H2(g) (HCl is Hydrochloric Acid)
Write in word equation please

2Li(s) + 2HCL(aq) —> 2LiCl(aq) + H2(g)

The word equation for the reaction is given below:

Metallic lithium reacts with aqueous hydrochloric acid to produce aqueous lithium chloride and liberate hydrogen gas

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
