Copper(II) Chloride and Iron lab

This lab was quite interesting even though I was absent for the second day of it. It was a little frustrating to try to catch up, and understand the measurements that my group members took. All in all it wasn't too hard to understand what we needed to find or calculate before the end of class. It was a little bothering tho that my group didn't tell me half the measurements.

Understanding Why Theoretical and Actual Yields Are Important

The difference between Theoretical and Actual yields are important because if you get them mixed up, or accidentally mistake one for the other your answer will be completely off. To simply put it the Theoretical yield is any amount that you use stoichiometry to solve or find the mass. An actual mass is something that you find from measurements, and does not have a chance of error.

Percent Yield

When we learned about percent yield it really wasn't a complex matter. The only park I didn't like was the x100 part. I thought it was implied if it was a percent then the decimal would move 2 places. Besides this it only got complicated when you had to make sure if you were using the correct element and if it was this element as a theoretical or actual value.

Stoichiometry

When it comes down to it Stoichiometry really isn't that complicated. There is 3 simple steps to getting the right answer and the only way to get it wrong is if you don't know how to do these three steps. You saw it in class too, the 3 simple steps can be seen here by using PT (Periodic Table) > BCE (Balanced Chemical Equation) > PT. Using these steps has never failed me.

Oxidation Reactions

In this reaction there are 2 agents. One agent is called the reducing agent, and ironically this agent is the element that is being oxidized. This element is donating an electron that actually makes the charge of this element have a charge that is not negative. Likewise, the other agent known as the oxidizing agent is the element that is being reduced, but it is actually gaining an electron. This donated electron changes the charge of the element to be negative.

Complete Ionic Equations

Ionic Equations the way I see them is for us to better see and understand how chemicals react and interact in a reaction. We see this from things like aqueous chemicals breaking into their two separate parts, and when solids and liquids are not separated or canceled out in the Ionic Equation. Overall I actually like them but I could really use to understand them better.
