online simulation was used to determine which substances were endothermic or exothermic when dissolved in water. According to the simulation‚ sodium chloride and ammonium chloride was observed to be endothermic. Calcium chloride‚ sodium acetate‚ sodium carbonate‚ and lithium chloride was observed to be exothermic. As sodium chloride and ammonium chloride was observed to be endothermic‚ those two salt substrates was not used in the experiment as the goal of the experiment was to increase temperature

Lab #18 Stoichiometry In this lab‚ we reacted aluminum foil with a copper chloride solution‚ and determined the amount of metal that should be produced‚ given the amount of aluminum used. First‚ we obtained a piece of aluminum with a mass of 0.809 g‚ and reacted it with 100 mL of Copper II Chloride‚ after heating the solution. Then‚ we filtered out the copper separated in the reaction using filter paper‚ massing 0.751 g. Once all the solution was filtered‚ we massed the new filter paper filled with
