Legend says that a faraway kingdom forged a sword that together with the power of the Elemental Gems (fire, water, air, and earth) could defeat any evil. Gather the gems to assemble the ultimate weapon and defeat the dragon hiding in the dungeon.

Start game

Thank goodness you’ve come! We need your help! You need to find the 4 Elemental Gems so that the sword has enough power and then defeat the fearsome dragon that is terrorizing our people…

Help us, only a person like you can do it!

No thank you, I’ll pass

Of course!

Ouch! I thought you were cool ... What will become of us!

Hehehe, I was kidding. Ahem, of course I’ll help you

I knew you would not fail me! Thanks a lot! Here is the holy sword. Now gather the Elemental Gems to complete it and defeat the dragon.

LEVEL 1 - EARTH GEM

EARTH GEM

Watch out, a wandering skeleton is in your way! Get the earth gem by passing a quiz about lorem ipsum…

Start level

Where do you think you’re going, mortal?! You won’t be worthy of the Earth Gem until you get all my questions correct. Do you dare to try?

Which of the following is the molecular ion peak in a mass spectrum?

The peak with the highest intensity

The peak with the highest m/z value

In mass spectrometry, neutral radicals that form as a result of the fragmentation do not reach the detector.

False

True

If you remove one electron from methane, what will be generated?

CH3+

CH4+

Which one of the following statements about the mass spectrum of CH3Br is correct?

there is just one peak for the molecular ion with an m/z value of 95

The last two peaks exhibit equal intensity and are observed at m/z values of 94 and 96.

Which fragment ion would correspond to a peak with an m/z value of 29

C-OH+

CH3CH2+

Congratulations!! Here is your reward, you have earned it

Hahahaha, what do you say? ...

Oh, I've lost my mind, give me another chance!
