CHEM120 Introduction to General, Organic & Biological Chemistry | University Lab Report Week 1 (A+ Graded)

This lab report covers the Week 1 practical session for CHEM120: Introduction to General, Organic & Biological Chemistry. It includes detailed experimental procedures, accurate results, and clearly explained conclusions that align with the course objectives. The report is formatted professionally and received an A+ grade, serving as a strong example for students completing similar coursework. Part 2: Complete Laster Lab Atomic Structure: Assess the possibility of life on other planets Complete all activities and answer all questions within the lab and then complete the activities below 1. Purpose: Describe in complete sentences and in your own words, the purpose of this experiment. 2. Observations: Record three observations from the simulation. I. The rocks collected were from different areas of the planet and contained 3 different colors/chemical make-ups. II. When tested using the chemical make-up, the gray/white rock created a chemical reaction, indicating that carbon was present on the planet. III. The differences between types of ions in, relies on the number of electrons gained or lost. Anions are negative and are ions in the presence of more electrons than protons. These gain electrons. Cation is the opposite. Losing electrons leaves cations with a positive charge notes by more protons. 3. In your own words, explain the terms below: a. Ion: When the atoms have different numbers of protons and electrons it is called ion. b. Isotope: atoms with the same number of protons but have different numbers of neutrons are isotopes. 4. Describe the three subatomic particles that make up atoms. Be sure that you include their locations within the atoms. Neutron, protons, and electrons. Neutrons are always in the center of the atom. Protons are heavy as neutrons; they are both in the center of the nucleus of atom and this is what makes the atoms. Electrons orbit the nucleus they are not part of it. 5. You have an atom of carbon with a mass number of 14. Determine the number of protons, neutrons, and electrons you would expect this atom to possess. - Normal carbon mass = 12, therefore mass of 14 indicates an isotope of carbon. - Protons are 6, indicative of carbon element. - Neutrons are 8, because of the mass being 14 the neutrons make the mass grater, but do not impact the charge. - Electrons are 6, because of no electrical charge the P and E are equal. 6. Reflection: Consider what you learned from this simulation. Reflect on three to four key concepts that you learned in this lab exercise. How could the lessons learned in this virtual lab relate to a real-world situation in the community/world or your future career? Be specific in your answer (this should require 5-10 sentences). In this simulation we have learned that the parts that make up the atoms on our periodic table, and the role all of those parts play in the make-up of the atoms individually. We also learned that charged atoms are called ions, these ions can be charged positively or negatively (cations or anions). These activities then helped us to create a chemical reaction to test for life on another planet. The planet was able to support life, and we found this information by knowing that the chemical make-up of the rock would react with the liquid solution releasing carbon. Carbon is an element made by the presence of carbon dioxide and liquid water, with we were able to conclude that the planet does have water, and carbon dioxide. Theoretically speaking this means the planet can support life. In my future work dealing with radioactive equipment and even some medications, these learnings will come in handy. Understanding isotopes, ions, and chemical reactions are imperative to understanding the chemical make-up of some medications and using forms of radiation such as chemotherapy treatments and radiation for cancer.
