Answer 1

Top box :-

• Denoted to one Cl

Hence it should be atom

#Top right box

• Denoted to KCl and CH_4 molecules

Hence answer should be molecules

#Bottom left:-

Denoted to Whole branching of KCl h.ce it's repeating atom group

#Last

CH_4 's extended structure is shown hence it's extended structure
