Lab 5: Nomenclature Puzzle Lab



Nomenclature Puzzle Lab

Introduction:

The overall purpose of this lab was to attempt to put a nomenclature puzzle together by matching chemical formulas to their corresponding names. This could most easily be done by singling out elements commonly found in many of the pieces like potassium, iron, calcium, etc. Each piece is a triangle which means that they should have three other adjacent pieces (unless on the outside) and the end result should be a large square shown below. This was also to help practice naming and identifying different compounds/polyatomic ions.



Conclusion/Reflection:

When completing this lab, the group I was in had a little bit of trouble. Our biggest challenge was that we all didn't understand the class material 100 percent, so after working on the puzzle for quite a bit of time, we found that we had made a mistake and nothing was fitting together. This unfortunately made us go back and retrace our steps to find the error and correct it. After finding and fixing the error with some help, we were able to put the rest of the puzzle together with no challenge. My biggest contribution to the puzzle was finding key elements in the formulas like potassium and iron on the pieces and making larger  which eventually fit together to form the puzzle. In the end, however, we were able to complete the puzzle so it was a success.

Lab 18: Alka Seltzer and the Ideal Gas Law Lab

Alka Seltzer and the Ideal Gas Law Lab Introduction: The purpose of this lab was to determine the mass of carbon dioxide released when a sample of alka seltzer is placed in water. This was done by collecting the gas in a balloon and measuring its dimensions after the reaction. This would allow us to get an estimate of about how much volume of gas was in the balloon and determine the amount of CO2 given off. We could determine the volume not only by measuring the size of the balloon but also filling the balloon to the same size with water and measuring the amount of water in a graduated cylinder.            (Balloon before alka seltzer put in water )          (Balloon after alka seltzer put in water) Data: Calculations: Analysis Questions: 1.    Discuss an area in this lab where expe r imental error may have occurred. One of the main spots we could have had an experiment al error was whe...

Lab 4: Atomic Mass of Candium Lab

Atomic Mass of Candium Lab Introduction: The purpose of this lab was to use a new element called Candium and calculate its average atomic mass. We were given several different quantities "Candium" atoms which represented different isotopes, and a scale. The important terms for this lab was isotope, percent abundance, and average atomic mass. An isotope is the different variations of the same atom just with different number of neutrons or different atomic masses. Percent abundance is the amount of an isotope that is present in the world in comparison to other isotopes, so basically how common the isotope is found. Average atomic mass is the sum of each type of isotope multiplied by its decimal abundance all divided by 100. Data: Our average atomic mass of Candium was 0.955 grams (0.71842)x(0.8376g) + (0.22407)x(0.985g) + (0.05809)x(2.29g) = 0.995g        ↑                     ...

Lab 11: Flame Test Lab

Flame Test Lab Introduction/Pre-Lab: The purpose of this lab was to observe the effect of certain compounds and more specifically elements in the compounds being burned. Basically, this means trying to find patterns of the flame color when different elements are burned. This was done by putting several known solutions on different wooden splints and putting them over a fire to see the change in color. Then, to test our ability of identifying the compound, we were given two unknown solutions and by observing the flame color when burned, we attempted to predict what compound it really was. 1.    What is the difference between ground state and an excited state? The difference between ground state and excited state is the energy levels. When an element's electrons are at their lowest energy levels available, it is known as the ground state. When an element's electrons absorb some form of energy, their energy levels raise causing the element to be at its excited state ...
