Trivia Thursday – Chemistry

I’m branching out a little and refreshing my chem knowledge with textbooks I got from a used bookstore and my awesome biochem major cousin, so in the spirit of that, I’m hoping you all will branch out a little too and try some gen chem problems with me 🙂 (Since these are science and math, I’ll actually work the problems tomorrow instead of just posting the answer so you all know how to get there.)

1. What is the mass of a 15 cm cube of iron if the density of iron is 7.87 g/cm³?

2. 0.2 grams of water contains how many molecules?

3. Balance this equation:  __ KOH + __ H3PO4 → __ K3PO4 + __ H2O

On Thursdays I’ll give you 3 to 7 questions on the law, literature, writing and/or science.

I’m holding you to the honor’s system.  No cheating, yes, that includes Googling and reading prior comments before you answer yourself. 🙂 For every answer correct, you get me to answer something on your blog, like critiquing a piece, and anyone who gets all questions of the week correct gets me re-posting a recent post of theirs.

The point of this is to engage and have fun, and hopefully learn something.  I’ll post the answers on Fridays around noon.

Go to the link and answer the questions in the comments section.  Honors system so no Googling 🙂
