Chem. Honors
Adendum #1 miscellany metal/nonmetal, penny in HCL, indistinguishability of gas, Identify un bopn beads, fix.
* Prior Knowledge to performing this laboratory: In order to perform this lab our group requisite to know a few basic terms forward we could start. The most important part of all these labs which I hire grouped into one addendum is electrons. Electrons (e-) are sub tingeic particles; electrons halt a neglible mass and are negatively illd. Electrons are find outside of the nucleus and fly around the nucleus at high-speed following no path or pattern. new(prenominal) important terms that were necessary to know before completing this lab were the oxidation state, number and what an oxidation agent was. The oxidation state of an atom in a chemical tangled shows how intensely an atom is oxidized a free segment always has an oxidation state of one. An oxidation number is the charge of an ion or the apparent charge of a nonmetal atom in a covalent bond. We also needed to know different types of reactions such as a Redox reaction.
* Materials: Classification metal/nonmetal, penny in HCL, identify of gas, identify mystical beads,
1. HCL
2. centime
3. Charcoal
4. Metal balls
5. Conductivity tester
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 hood
4. Electricity
* Procedure: Classification metal / nonmetal lab
1. Touch two the negative and positive sides of the conductivity tester to the object.
2. Look at led, if the led blinks rapidly this means the object is conductive.
3. visitation each object at least twice to match there are no human errors.
* Procedure: Penny in HCl
1. Add 25 drops of HCL into test tube exploitation a dropper.
2. Add four balls of metal into the test tube and record results.
3. Collect the gasses that come off the mixture with a slightly bigger test...If you want to get a wide essay, order it on our website: Ordercustompaper.com
