States of Matter Lab
In this lab, we explored the different states of matter and how substance change from one state to the other to help us understand the different states of matter. Using several different short experiments, we observed the different qualities and characteristics of gases, liquids, and solids. We also learned the differences between the three states, the difference between the states of different compounds and elements, and different characteristics such as surface tension, volume, shape, compressability, and density.
Iron-Copper Molar Tango
The iron-copper molar tango lab demonstrated a single-replacement reaction using iron and copper (II) sulfate pentahydrate to create copper and iron sulfate. This lab was also an example in which we used stoichiometry in a real situation, not just in random equations done in class and for homework. Using stoichiometry, we had to determine the molar relationship between iron and copper, which we had determined should be 1:1 using a balanced equation of the chemical reaction. When we completed the chemical reaction and the proper stoichiometry, we revealed that the actual ratio was around 1:1.34, and we had a 25.42% error. Even though our experiment had some error, we still managed to improve our stoichiometry skills.
