Hi Brilliant! I recently wrote my National Science Olympiad and I really want to compare my answers with your answers.
Please look at my comments below and try solve the problems with clear explanations.
Update: Keep this note on reach, because there will be more questions tomorrow!
Update (2014/03/09): Another 5 Questions are added. Look for the questions that say "UPDATE 3". Chemistry forms an inextricable part of Science. Wait for the Chemistry problems from my Science Olympiad tomorrow!
Don't forget to like or re-share this note to keep getting more problems.
Thanks again to all the people that are contributing to this note. I'm learning so much!
