Vinegar: First of all, the kind of vinegar you get at the grocery store is about 95% water, but the vinegary part is acetic acid (also called ethanoic acid or methane carboxylic acid). The formula is written: CH3COOH.\n\ncoke: do u mean cocaine its C17H21NO4\n\nand i forgor about the nail polish remover its like this:\n\n"In chemistry, acetone (also known as propanone, dimethyl ketone, 2-propanone, propan-2-one and β-ketopropane) is the simplest representative of the ketones.\n\nAcetone is a colorless mobile flammable liquid with melting point at -95.4 °C and boiling point at 56.53 °C. It has a relative density of 0.819 (at 0 °C). It is readily soluble in water, ethanol, ether, etc., and itself serves as an important solvent. The most familiar household use of acetone is as the active ingredient in nail polish remover. Acetone is also used to make plastic, fibers, drugs, and other chemicals."\n\n\n\nis it good?!

This seems more like a physics question than a chemistry question.  I would try posting this in the physics section- someone will be able to help you there!

Science - I had fun with the experiments especially in year 9 where we get to test the chemicals using flame colours.  It was really cool :)

Interesting question for the science section

Great idea.  What is your hypothesis?  What experiment will you do?  What data will you collect?  How will you interpret it?

i'M IN SIXTH GRADE, AND A GOOD SCIENCE FAIR TOPIC WOULD BE "WHICH SUBSTANCE CONDUCTS ELECTRICITY BEST". iT IS REALLY EASY TO DO AND YOU CAN HAVE LOTS OF GRAPHS. FOR EXAMPLE I HAVE 21 GRAPHS. AND MY WHOLE ENTIRE BOOK IS 93 PAGES LONG. \n\nHOPE i HELP YA!!
