Story

A game by Mr. Riendl (and this presentation site:'Genially')

I found this website that makes learning better? I thought I'd spend a couple of hours and make chem questions. Oh, your goal? Make a sword powerful enough to kill a dragon by collecting CHEMISTRY GEMS!!

Thank goodness you’ve come! Mr. Riendl doesn't want to teach you today and instead he spent hours making a this 'lesson'. Also: I have lost my eye balls.

Shortcut

Will you play this game?

^(@# off

Of course!

Woah! That's not AGS appropriate language. I thought you were cool ...!

Good bye.

Great news! Now you can review acid and bases. Here's a sword, but it is weak; it needs CHEMISTRY GEMS!

LEVEL 1 - pH

PH GEM

This is something important. You'll want to earn it. The sword is like a gauntlet that hold stones. You need to earn them all to save the universe...er...kill the dragon. There's a skeleton on the next page. Don't be afraid. His bones are made of carbonate and there's surely a fact about acids and carbonates you have been asked to memorize.

Start level

I don't think you have done enough chem studying. To earn the pH game you must attack me. (or throw acid on me, because acid + carbonate makes salt, water, and carbon dioxide gas)

Which has the higher [H+]?

[H+] = 103

pH = 3

What the conjugate acid of HCO3-?

H2CO3

HCO3- is its own conjugate

10-2

12

If the pOH of a solution is 12, then the [H+] = ?

10-12

...is exactly a Bronsted-Lowry base.

...donates protons.

An Arrehnius base...

...create hydroxide.

...accepts protons.

2, 4

In the picture, which pair are acting as acids?

1,3

1,2

Wow, you sure can answer those questions right. Here's the pH gem. Which is green. It's actually called the 'earth gem', but Mr. Riendl changed the text. So if it's called the 'earth gem' elsewhere...someone was being lazy.

DMAN ITITLKAL! Why have you not been listening in class?

Okay, I will turn off my Blackberry and learn good.

LEVEL 2 - pKA GEM

pKa GEM

Choose the correct image to get out of the room alive (and to get the next gem)

Start level

Which model best shows a strong acid?

A weak acid solution and a lightbulb might look like this.

The equilibrium constant expression for the conjugate base of CH3COOH

The equilibrium expression for the conjugate acid of A-.

Shows water acting as a base...

Hooray. You got the glass gem...no wait...er...the 'pKa gem'. Yeah! Your chem sword is almost strong enough for some dragon slaying!

LEVEL 3 - WATER GEM

WATER GEM

Drag the light to find the correct answer

wade into the chest high water

Did you read the instructions? What is the H+ concentration if the OH- concentration is 10-12?

10-2

10-12

102

When equal moles of a strong acid and a weak base are added, the solution will be...

neutral

acidic

basic

If water is neutral, how does the [H+] and [OH-] compare?

both must be 10-7

they are equal

both must be 10-14

Calculate the pH of 0.020 mol dm-3 HCl.

0.02

9.1

7.6

3.2

1.7

And now look for the gem!

You got the Water gem!

Dragging light spheres is hard

I want to try again

I really want to try again

LEVEL 4 - Indicator GEM

Indicator GEM

Search among the tiles to find the question.

I must search the room...

I sense a question about an indicator's colour...

red

orane

yellow

1 mole HCl

0.5 L of 0.1 M NaOH

phenolphthalein?

I feel a certain colour will guide me...

pink

bromylthymol blue

colourless

The species will the highest concentration will lead me to the gem...

A final colour selection will get me out of this dungeon...

INDICATOR GEM!

You did it! You found the blood, no, fire, no health, no no..what was it? (hover above your head)

RUN AWAy

I will learn again.

FINAL LEVEL - DRAGON

YOU HAVE ALL THE GEMS. Now you can fight the dragon. Because the dragon will only fight you once you are strong. He wouldn't want to win the battle by fighting you before the pH gem.

Defeat the dragon!

You have done some chem studying....now: can you use the trackpad?

A 0.50 mol dm-3 solution of weak acid HX is found to have a pH = 4.3. Determine pKa

HEAD SHOT

after an epic battle, you stab yourself with your sword

awp bat

these gems send you back in the story

THE END

You used the track pad well.

you could go to a problem set now. :)

But, the game?

SURE YOU WANT TO GO OUT?
