When we think of chemicals, we tend to think of liquids, but in fact chemistry is a huge subject which covers far more than that. It is the science of what makes up the physical world, i.e. all physical matter,, comprising gases, liquids and solids. These can be either organic or inorganic. How much do you know about this fascinating and often difficult subject? Do this fun quiz to find out!

Question of
Thinking caps on for this one! What is the correct form of this equation?
-
HCl (aq) + NaOH (aq) → NaOH (aq) + Cl (g)

Good score!! Thanks for taking part.
Chemistry isn’t my thing. Not going to say how many I got right.
Haha! It doesn’t matter TheOfficialAndrew, it’s only a fun quiz! I studied chemistry but I have forgotten most of what I learned now.
I asked quizzes seriously.
I only got 3/9! I need to brush up on my science.
I think it was quite a tough quiz anyway Waleed
lol only 2 correct but i know some answers while child but not now..
I know birju danak. All the stuff we learned at school, eh?
5/9! Good quiz! I liked the “alkali” question – one of the suggested answers: “Person with a drinking problem.” LOL
Thanks Marita! Yes, I was trying to make it amusing and fun.
8/9
Excellent Gary! You clearly know a lot about chemistry, since it was quite a hard quiz.
Yikes only got 5!
I think it was quite a hard quiz wasn’t it Carol?
7/9 Very nice quiz!
TY Gina!
Nice quiz, Maggie! 6/9
TY Nornan!
