Mole-Mass Relationships Lab

Purpose of Lab

The purpose of this lab was to educate students on mass-mass relationships. Students can learn more on how these relationships occur in chemical reactions and in balanced chemical equations. 


Lab Manual Questions 




Our Product After Evaporation



Possible Error

Sources of possible error in our percent yield include how our substance had too much acid evaporation, which may have caused changes to our actual yield. Also, when we were adding the acid to the NaHCO3 with a dropper, we dropped the acid a little quicker than we should have, contrary to how the instructions tell us to gradually drop the acid in.

The purpose of this lab was to investigate chemical reactions that cause solids to form. Our wellplate of the reactions  Net Ionic Equations What surprised me the most was how quickly the precipitate formed, especially in reaction 6 with NaOH and Cu(NO_3)_2.

Flame Test Lab

Image
Summary In this lab, students were given many different substances to hold over a flame and were asked to observe the colors of the flame produced. This helped demonstrate the relationships of the flame colors and the certain atoms contained in compounds. Pre-lab Questions 1) What is the difference between ground state and an excited state?  Ground state is the most stable state where all the electrons are in the lowest energy levels. On the other hand, an excited state is where the electrons are in an unstable arrangement, and will go back to their normal positions of lower energy. 2) What does the word "emit" mean? The word "emit" means to "produce and discharge", especially in gas or radiation. 3) In this experiment, where are the atoms getting their excess energy from? In this experiment, the atoms are getting their excess energy from the heat of the bunson burner's flame, where the electrons can reach an excited state. 4) Why do ...

Atomic Mass of Candium

Image
Purpose of the Lab The purpose of this lab was to practice our abilities of finding the total and average mass of isotopes, determining percent and decimal abundance, and finding the average atomic mass. We did this with a given random combination of skittles, m&m's, and pretzel m&m's.  Average Atomic Mass (0.603x0.864)+(0.30x1.02)+(0.10x2.09) = 1.036 = 1.0.  Conclusions 1. Ask a group nearby what their average atomic mass was. Why would your average atomic mass be different than theirs? The other group's average is 1.23. Our average atomic mass might be different because each isotope--skittles, m&m's, and pretzel m&m's--had a different total number, and thus a different total and average mass. This affected the average mass because the formula for it, average atomic mass = (decimal abundance of isotope 1 x mass of isotope 1) + (decimal abundance of isotope 2 x mass of isotope 2) + (decimal abundance of isotope 3 x mass of is...
