Ryan Taber Lab Addendum

Ryan Taber Mrs. Sager March, 6, 2012 Chem. Honors Adendum #1 miscellany coat/nonmetal, penny in HCL, identity operator of gas, Identify un bopn beads, fix. * Prior Knowledge to performing this research laboratoryoratory: In order to perform this lab our group requisite to kip down a few basic damage forward we could start. The some important part of all these labs which I hire separate into one addendum is electrons. Electrons (e-) are sub tingeic particles; electrons halt a neglible mass and are negatively illd. Electrons are find immaterial of the nucleus and fly around the nucleus at high-velocity following no path or pattern. new(prenominal) important terms that were necessary to know before completing this lab were the oxidization state, number and what an oxidation agent was. The oxidation state of an hint in a chemical tangled shows how intensely an tinge is oxidized a free segment always has an oxidation state of one. An oxidation number is the charge of an ion or the homely charge of a nonmetal atom in a covalent bond. We also needed to know different types of reactions much(prenominal) as a Redox reaction. * Materials: Classification metal/nonmetal, penny in HCL, identify of gas, identify mystical beads, 1. HCL 2. centime 3. oxford grey 4. Metal balls 5. Conductivity mental visitationinger 6. 1 beaker 7. 2 test resistances * Materials: pickle lab 1. Pickle 2. Negative and positive ends of a electrical outlet cord 3. roll of tobacco tough 4. Electricity * Procedure: Classification metal / nonmetal lab 1. Touch two the negative and positive sides of the conductivity inspector to the object. 2. Look at led, if the led blinks rapidly this way the object is conductive. 3. visitation each object at to the lowest degree twice to match there are no human errors. * Procedure: Penny in HCl 1. Add 25 drops of HCL i nto test tube exploitation a dropper. ! 2. Add four balls of metal into the test tube and record results. 3.
