Question: does anyone remember this movie?

I can’t remember the movie title, but it was about an over weight kid that was working on some big science experiment for college. He also asked the pretty girl at school to the prom, but his nerdy friend leaked an embarrassing video of him. He wore a plum suit to the dance, and got the girl in the end.
that is it! thanks! BA to you.

Junior Cert – Science Experiments – Chemistry 1 of 4

Question: lightbulb experiment?

i’m studying for a chemistry quiz in lab.
i’m a little confused about the lightbulb experiment results bc i wasn’t there for the experiment.

when using these solutions below, does the lightbulb burn bright, dim, or not at all?

non-electrolyte= doesn’t burn at all (correct?)
electrolyte= ? (burns yes, but bright or dim?)
weak acids and bases= burns dim? or does it depend on if it’s an acid or base?
strong acids and bases= burns bright? or again, does it depend on if it’s an acid or base?

neutral pH= ?

thankyou so much for any help.

Answer: I have not done your lightbulb experiment, either! But it is straight-forward.

non-electrolyte= doesn’t burn at all (correct)
electrolyte= burns (bright)
weak acids or weak bases= burns dim. It does NOT depend on if it’s an acid or base.
strong acids or strong bases= burns bright. It does NOT depend on if it’s an acid or base.

neutral pH= Depends on if the liquid is pure water or an electrolyte solution
