Answer 2

frankly speaking I hate Chemistry

I don't know anything about chemistry i wasted my 2 years of high school

in chemistry subjects

it annoys me

i hate this subject

i got 4 out of 70 in exams of chemistry many times

12 out of 100 in chemistry in 12 grade

Answer 3

if it all was wrong, how could one develop certain complicated substances ? how could you create a substance that has all the qualities you want it to have ? this would be impossible if all the assumptions were wrong.

good scientists can PREDICT which qualities a new substance could have if they created it.

you can't predict anything without having any right ideas about how it works in general.

Answer 4

probably heaps of testing

Answer 5

If your speaking about atoms, i believe that the specific weights have been confirmed with the use of electron microscopes.  As for before these microscopes were developed, I'm not sure.
