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

This document is a lab report for Week 1 of CHEM120: Introduction to General, Organic & Biological Chemistry. It includes experimental data, observations, calculations, and conclusions based on the initial lab exercises. The report is well-organized, clearly written, and received an A+ grade, making it a valuable reference for students preparing for lab sessions or writing their own reports. CHEM120 Introduction to General, Organic & Biological Chemistry | University Lab Report Week 1 A+ OL Lab 1: Chemistry Safety and Atomic Structure: Assess the possibility of life on other planets Learning Objectives • Identify the hazards posed by chemicals and how to handle them • React quickly and save lives in case of a fire emergency • Use the CAS numbers to plan your experiment • Understand how to dispose of halogenated and non-halogenated waste • Lookup H and P phrases in the safety data sheet • Safely use a chemical fume hood • Explain the concept of an atom • Explain the properties of the basic subatomic particles: protons, neutrons, and electrons • Define the atomic number and atomic mass • Define isotopes • Identify the basics of the quantum atomic model and describe the significance of the four quantum numbers Dangers in the lab In the Chemistry Safety lab, you’ll learn to identify the hazards posed by the different chemicals that you are using, which is a very important step in the planning of every experiment. Atoms and the subatomic particles Everything you see around you is made up of atoms, and all atoms consist of subatomic particles. In the Atomic Structure simulation, you will learn the names and properties of the basic subatomic particles and understand how changing the number of electrons may charge an atom either positively or negatively. Identify different elements from the periodic table As a part of your mission, you will be teleported to an exoplanet to explore on your own, collect samples and come up with observations regarding the presence of life on the planet. Back in the laboratory, you will investigate the properties of the elements you brought back from the exoplanet. The periodic table will be close by to advise and guide you. What is an isotope? In order to understand the main properties of an isotope in the Atomic Structure simulation, you will use the holo-table. The quantum model and quantum numbers At the end of the simulation, you will be introduced to the quantum mechanical model of an atom and the four quantum numbers that provide all the necessary information to describe the orbits of the electrons around the nucleus. Part 1: Complete Labster Lab Chemistry Safety Complete all activities and answer all questions within the lab and then complete the questions below: 1. Look up an MSDS of the chemical HCl. What are the major hazards and what precautions would you take when handling this chemical? Causes the eyes and skin burns. It causes the digestive and respiratory tract burns. May be fatal if inhaled or swallowed. Repeated or prolonged exposure may cause erosion of exposed teeth. Corrosive to metal. According to MSDS 2. Why is proper waste disposal important in a lab setting? Proper waste disposal ensures chemical safety. This makes sure everyone in the lab is safe when and if chemicals are disposed of and makes sure their methods of disposal do not create any hazardous environment. 3. Why is the proper usage of personal protective equipment (PPE) key to a safe lab experience? PPE that is properly used accurately protects you from dangerous chemicals/environment. Properly using the PPE equipment ensures that you and others are kept protected safe and minimizes accidents in the lab.
