    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

    something + 2Fe+2 Equation 2: 8H+ + 5Fe+2 + MnO4- --> 5Fe+3 + Mn+2 + 4H2O Equation 3: 6H+ + 2MnO4- + 5H2C2O4 --> 2Mn+2 + 10CO2 + 8H2O Conclusion: Therefore the concluded reaction would be: NH3OH+ + 2Fe+3 --> N2O + 2Fe+2 This was obtained by using stoichiometry half reactions the product of that reaction was determined to be N2O. Some systematic errors could be if the wrong molarity was determined for the permanganate because then that would though off the calculations for the Fe+2 and the rest of the

    One density dependent limiting factor is parasitism. This describes organisms that live off a host that can easily pass from one organism to another because they are close together. Parasites are more likely to spread through a population if the population density is high. 1. One density independent limiting factor is natural disasters‚ such as fires‚ floods‚ and tornadoes‚ each of which can wipe out a significant number of a population. 2. Another density dependent limiting factor is competition
