Introduction: In this lab we took Nickel Chloride and water, known as the hydrate reactant, and precipitated it with ethylenediamine. This allowed us to find out which chemical was the limiting reactant in the equation NiCl 2 x 6H 2 0 + 3C 2 H 8 N 2 Ni(C 2 H 8 N 2 ) 3 Cl 2 + 6H 2 O If there are more than 3 mol’s of C 2 H 8 N 2 per 1 mole of NiCl 2 x 6H 2 0 then the C 2 H 8 N 2 is present in excess and therefore, NiCl 2 x 6H 2 0 is the limiting reactant. If we need more than the available moles of C 2 H 8 N 2 than Nickel Chloride is the limiting reactant. Questions: 1) The observations that took place that led us to believe a chemical reaction took

Unformatted text preview: place were as follows: when we mixed the green granulated NiCl 2 with the C 2 H 8 N 2 the mixture turned dark blue than purple. When the acetone was added it became slushy, and turned light purple. The beaker with the mixture became warm. These observations are key factors in a chemical reaction. 2) Our % yield was 77% which is 23% off, this was probably so far off due to incorrect measuring, and we had a small spill during the exchange of chemicals. Specifically, when we added acetone in 5 mL increments, some product was lost....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
