This is the Base Model in Chemistry of Silver Nitrate and Copper.
2 AgNO3 (aq) + Cu (s) ---> Cu(NO3)2 (aq) + 2 Ag (s)
Assumptions in this model:
Each agent of Silver ion or Silver Atom represents 2 atoms as indicated by the size of agent.
Each agent of Copper represents 1 atom as indicated by the size of agent.
Each agent of water represents 1 mL of water.
Example of chemistry concepts covered here:
1- Conditions for a chemical reaction to occur
2- Evidence of a chemical reaction
3- Limiting agents versus agent in excess
4- Reaction stops when limiting agent is consumed
5- Balancing equations and Stoichiometry
6- Amount of Silver created is determined by the limiting agent
