Love this idea and kudos to miniturtle for making Chem so fun! I hope everyone gets on top of this 

[Bri MT]

Since there's equal votes for 2 options I'm going to go for the later one so there's more time for people to realise this is happening.

The kahoot will run at 4:30pm Tuesday the 12th of February

As a general request can you clarify the date as Tuesday and 10th are two different days 😂 hahaha but kudos to you, amazing work xxx

Haha yes definitely. I meant the 12th and have edited the above post now  - thanks for letting me know

Thank you!!

Loading up the kahoot now

You'll have until 4:40 to join


Edit: Make that 4:45 since I didn't actually share the code  ( 767774 ) originally

Join using the app or kahoot.it

What's the code?

Sorry! Somehow missed putting that in the previous post
It's 767774

Don't you need to be able to see the main screen to play kahoot O.o

I've posted all the questions now (left it til late to avoid research/cheating) and the options
top left is a, top right is b, bottom left is c and bottom right is d

Does that make sense now?





Alrighty everyone, the questions list is now in the opening post and here:

Best of luck and I'll explain answers as we go

Owl narrowly in the lead.

remember that n = cv


I'll ecplain the fuel question in more depth afterwards since that tricked almost everyone

RN in the lead now



Both exo- and endo- thermic reactions can be spontaneous


Oxygen in a carbon chain should be thought of as slightly negative


water is the most common greenhouse gas


RN still in the lead but Lear has maintained a solid 2nd the whole way through


For addition and subtraction use decimal places


this was a lot quicker than bio - in future I'll make more questions for the chem students


Congrats to all!

[PhoenixxFire]

Well, I definitely hadn't learnt enough chemistry for that

[hums_student]

That awkward moment when you thought the options were
a)     c)
b)     d)
for the first 4 questions 

Don't know who won but @Lear good job mate, I was only like two thousand points behind you

EDIT - 4 thousand points. Ooops.
Congrats to RN

[Lear]

Well that was fun. I always forget about the decimals rule when adding and subtracting hah!
Thanks for doing this for us, Miniturtle.

Just for future Kahoots, it would be great if you could number the questions you post on forums. I almost lost track mid way through that one!

Oh and well done RN

Thanks for the feedback - will do in future
