16 is d for sure ,because during explosions very strong heat is released immediately and not gradually . so it increase and after explosions it decreases again

Wahab09:
guys.. how the hell is 39 B..
its C for sure..

how the hell can u even get an empirical formula without knowing the % and stuff..

molecular formula is the same..
c 12 and c 12 make 24
h-h-h-h= 4

24+4 = 28..

the same with polyethene!
