Chemical Dominoes
This project was our first one in Chemistry, and was meant to be more of a review project than a learning experience. It was meant to solidify what we had recently learned about types of reactions, and their effects.
What we actually did was make a board game that had to involve certain types of reactions while it was being played, and then we were set loose. My group ended up deciding to make a version of battleship, but we shifted some rules and added new components to the game wherever we felt the need, or if we had requirements that couldn't be comfortably fit into the basic rules.

Concepts
Reactants: The left side of a chemical reaction, before the reaction has occurred
Products: The right side of a chemical reaction, after the reaction has occurred
Synthesis RxN: A + B -> AB A=cation; B=anion
Decomposition RxN: AB -> A + B A=cation; B=anion
Single Replacement RxN: A + BC -> B + AC A mono-atomic cation/anion swaps with the cation/anion in a poly-atomic compound as long as the mono-atomic cation/anion is higher on the reactivity series than the one in the compound
Double Replacement RxN: AB + CD -> AD + CB two poly-atomic compounds swap cations and anions to form two new compounds

Cu(NO3)2 + Na2(CO3) -> Cu(CO3) + 2Na(NO3)
2FeCl3 + 3K2CrO4 -> Fe2(CrO4)3 + 2K3Cl2
2FeCl3 + 3Na2(CO3) -> Fe2(CO3)3 + 6NaCl
Cu(NO3)2 + K2(CrO4) -> Cu(CrO4) + 2K(NO3)
Cu(NO3)2 + Na2(CO3) -> Cu(CO3) + 2Na(NO3)
synthesis
Destroyer being hit: Magnesium Strip reacts with the Oxygen in the air through being heated
2Mg + O2 --heat--> 2MgO
2Mg + O2 --heat--> 2MgO
Reflection
In this project, my group did good work and if they weren't adding new ideas, they were always willing to execute others' ideas, which came in handy throughout the entire work process. However, this meant that for such an open-ended project, planning largely fell onto the heads of only half of our team, which was quite difficult to deal with. The second failing, which was on my personal part, was mostly due to my lack of action due to decision paralysis. Since there were so many things to be doing at every moment in the project, I found myself often taking significantly more time planning things than physically advancing our project. While this was a setback in terms of work time, it did make our final project vastly more cohesive than it would have been otherwise.
