Background Chemistry is an experiential science and involves "doing something. Unfortunately, as we continue to be online you are still only able to watch a video of what is happening, and with this experiment you would not be able to do the experimentat home. We will, however, continue to be interested in examining what is happening on the molecular level In 1947, the reaction of sodium and water was responsible for the death of America's Lake Lenore (even to this day) In Experiment you will examine this reaction as well as how the reaction differs as you consider other Alkali metals (Li and K) When you watch the video related to this process two chemical reactions will be of interest (equations 1) and 2 2M + 2H0+ H+ 2M 2011 OH + HHO 121 (opratanana lea) You will examine how to describe to someone not only what is happening on the molecular level but also out to them why it is happening When attempting to visualize what is happening on the molecular level a chemist considers that it is a single atom of the metal that will be reacting when this is the case, as chemical processes involve changes in Valence electrons, it is important to know the electron configuration of the atom. Once you know what to look for in an electron configuration to understand the reactivity of the atom, you also have to know what to look for when you compare the reactivity of several metallic atoms Electron Configurations which are com con conductor mportant to know the hould be you morant Periodic Properties When comparing to hermoreskamatwa The concorrente your CHEM 201 - Water 2002 When you observe something in the lab, although many reactions may be taking place, not all reactions are relevant to the chemical process taking place. Some reactions ? might he occurring because a chemist is trying to obtain supporting evidence for the products fomed by the primary reaction of interest ? Chemical Equations What is the importance of you change Man ution2 change Why For any reaction, Lewis diagrams can be used to represent the bonding in a chemical species, and curved arrows can be used to show the electron movement related to the hond breaking and bond-making that occurs when products are formed. The chemical reaction of interest in this experiment (cquation (1) is an idio-eduction reaction It involves the transfer of single electrons and such mechanisms are very complicated and beyond the scope of Chemistry 201. You should, however, be able to propone a mechanism for the secondary acid huse reaction in this experiment equation (2), which involves pairs of electrons and bond-making and becaking Curved Arrows Can you the he law diagram The Goal of this Experiment: You will observe the reaction between cach of three Alkali Metals with water. You will qualitatively examine how macroscopic observations correlate to molecular ones. You will use what you loom to make a Claim-Evidence Reasoning Argument (CER) that answers a given research question (remember further details regarding CER are posted in DL, Content > Lab Activities > Structure of Laboratory Activities) YOU SHOULD FIND THIS EXPERIMENT AND WRITEUP MUCH EASIER THAN THE LAST AS IT IS VISITING LEARNING OUTCOMES THAT YOU HAVE DEALT WITH QUITE EXTENSIVELY. If you do not find this experiment ensier, you need to seek the help of your instructor
