Answers to day 12 of the quiz

Posted on by

And here we are at the end. The answers to yesterday’s quiz are as follows:

275 molecules of water is the minimum number needed to form an ice crystal or the world’s smallest snowflake. You can read our story here.

Eating a big turkey Christmas lunch is reputed to make you feel sleepy, but this is a myth. The levels of tryptophan in turkey are comparable to other meats.

We hope you’ve enjoyed the quiz. Thanks to all for your answers.

Chemistry World tablet editions

Posted on by

We told you about this last Christmas but a year is a long time so let me remind you again: if you get a tablet device for Christmas, one of the first apps you need to install is the Chemistry World app.

The digital edition of Chemistry World is available from Google Play and iTunes and is free to download for all RSC members and e-members. You can log in, choose the latest issue or a back issue or and swipe through it just like the printed publication. And don’t forget you can download the issue for offline reading at a time that is convenient for you. So get downloading!

Also please do let us know what you think. Any feedback to chemistryworld@rsc.org would be most welcome.

And if you are not yet an RSC member or e-member you can now join via the Chemistry World website at http://www.chemistryworld.org or on the RSC website at http://www.rsc.org/membership.

Chemistry World Christmas quiz, day 11

Posted on by

On the eleventh day of Christmas, Chemistry World brought to you, the penultimate day of the quiz. And straight in with the first question.

In January, we found out that the caffeine levels in espresso coffees purchased from many coffee shops are well above the recommended daily allowance for pregnant women set by the Food Standards Agency in the UK. What’s is this recommended daily allowance for pregnant women?

Which explosive compound would you find in small amounts in your Christmas cracker? 

And now on to the answers from yesterday’s quiz.

It was Lee Cronin‘s group at Glasgow that printed their own labware.

John Millington gave the first ever Royal Institution Christmas lecture in 1825.

See you all tomorrow for the final round!

Chemistry World Christmas quiz, day 12

Posted on by

Drum roll please! It’s the twelfth (and final) day of our topical Christmas quiz. On with the show!

In September, we learnt what the minimum number of water molecules needed to form an ice crystal was… How many was it?

Which amino acid reputedly found in high concentrations in turkey is supposedly what makes you feel like having a nap after your Christmas dinner?

Now the answers to yesterday’s quiz.

Pregnant women shouldn’t consume more than 200mg of caffeine per day. Researchers discovered that a single cup of some takeaway espressos contained more than 300mg of caffeine! You can read more here.

The explosive that you’ll find in your Christmas cracker is silver fulminate.

We’ll be back one more time tomorrow with the answers to the last questions. Thanks for following.
