okay...heres the answer BBDABDACCCB *

HAha big bro some of your answers are
WRONG.

1you mean oxygen is passive to Nitrogen I oxide.??
2you mean alkanes (paraffin eg METHANE ) no longer cause explosion??
3so the variation of gravity is no longer caused by the uneven shape of the earth
6.so yellow spot is no longer the most sensitive part of the eyes
7. so Brewster law n= tan tita now obey inverse square law.??
8 BaCL nko? no longer used??
10, helium has a duplet structure na
11. caesium is more positive than potassium joor.
