For this project, we were asked to create some sort of themed board game, and incorporate the following reactions: Single Replacement, Double Replacement, Production of a Gas, Lighting of an LED, and chemical and physical changes of energy. We were also required to include blueprints of the game, playing instructions and set- up, safety precautions, an explanation of each reaction, and of course, a sturdy game board and playing pieces. We created a slideshow presentation to present all of this information, which can be found below.
Break of inner glass tube releases hydrogen peroxide which releases a great amount of energy cyclin peroxide, allowing the interaction with fluorescent dye molecules.
Reaction#2: Single Replacement/ Light an LED by destroying a metal
An element replace its like element in an ionic compound or acid
AB (aq) + C -> CB (aq) + A
Cation anion + metal ->cation + metal
Must use activity series (don’t react if violate activity series)
the aluminum replaced the less active metal copper in the aqueous solution
The aluminum connects a resistor to the circuit with an led. The resistor has too much resistance to allow the LED to light. When the metal is dissolved, the resistor is disconnected, allowing the LED to light
This is a double displacement reaction meaning that: the cations and ions switch between the reactants to form a new product.
Since Carbonic Acid is unstable, it undergoes an individual decomposition reaction hence producing CO2 (the gas)
We will use the gas to fill a balloon, which will push a lever. The lever will pour a cup of Manganese Dioxide into a beaker, which will start reaction #5.
Reaction #5: Decomposition
2H2O2 + MnO2 → MnO2 + O2 + 2H2O
hydrogen peroxide + manganese dioxide -> oxygen + water
When H2O2 is added to MnO2, the rate of the reaction increases significantly.
Manganese Dioxide catalyzes the decomposition of hydrogen peroxide into Oxygen and water, and is not consumed in the reaction.
One complex molecule decomposes into two or more separate elements
The Game Board
We decided to make our game alchemy/ wizardry themed, hence the name "Alchemania".
Reflection
Overall, this project was successful for our group. It required us to dig deeper into the workings of reactions, and I feel that I gained a significantly better understanding of the different types of reactions. It also required us to use creativity in fitting our theme, and making it appealing for players of all ages. Our biggest struggle in the process was lighting an LED by destroying a metal. I had difficulties setting up the breadboard in the perfect way, and had to spend lots of extra time outside of class in order to find away. Thankfully, I managed to light the LED by destroying a metal, just in time for presentation night. At game night, the judges seemed to like our game. Even children liked our game; they started crying when their parents said they had to stop playing and had to leave, because it was past their bedtime!
