Views on Stoichiometry

Since our Stoichiometry unit exam was today, I thought I'd just share some thoughts. First, overall this is not a very hard unit, if you study. However. what I seemed to have the most trouble on was finding the theoretical yield. It seemed like no matter what I did, I could not get my answer to match up with any of the selected answers. But that will not happen on the final, hopefully. However, as the last blog post for the semester, I have found some relatively enjoyable videos for everyone. Enjoy!!!

Remembering the Driving Forces

Remember, driving forces are different in each type of chemical reaction. In single replacement reactions, the driving force is a precipitate. In an acid-base reaction, it is the formation of water. In a double replacement reaction, the driving force can be either a precipitate, the formation of water, or even a gas. If you are still having trouble, these links can help.

Atomic Refresher Part 2

This post is another refresher of atomic structure and radioactivity in preparation for the final. I hope this one, as I do the others, will be most helpful for those studying for the final.

Awesome Reactions Part 2

In Day 2 of our Stoichiometry Lab, we removed both the nail and the water from our baby food jar. We then added HCl to the jar to clean off the copper(II) chloride, and then proceeded to dump out the acid. We then added water again to clean out the rest of the acid and dumped it. Then we took the nail's balance.

Awesome reaction Part 1

In Day 1 of our Stoichiometry lab, we added copper(II) chloride to water in a baby food jar. We then added an iron nail. The resulting reaction caused the copper(II) chloride to dissolve and turn the water blue. Exciting!

Troublesome Test

Today was our Stochiometry weekly quiz #1. I have the formulas down, but for some reason my answers didn't turn out right all the time. Did anyone else have that problem or is it just me? Just in case, if anyone might need these, here are some helpful websites regarding Stoichiometry.

Volatile Reactions

Today we had our Reactive Metals Lab. It was neat seeing the reactions that took place. I noticed that Calcium is highly active whereas copper tends to be inactive when combined with different chemicals.

Help with RedOx

For those of us who still need help with grasping RedOx reaction, I have found a website that I fell will be most helpful, especially with the upcoming test.

Remembering RedOx

Today we learned about RedOx chemical reactions. While this may be easier than double replacement recations, these are still hard to get. As long as I pay attention to what metals/nonmetals react with, I should be fine.

Awesome Reactions!

Today we had our Solubility Lab. It was really neat seeing how the chemicals react with one another and how quickly they react. I was able to get some pictures of some of the chemicals mixed together and I put them below.

Chemistry Nightmare!!!

I think I am speaking for the majority of the class when I say that the Chemical Composition exam was one of the hardest we have taken this year. It was stressful and not very many people finished before the bell rang. Some of us still may have trouble, so I have found a video and a website that can help people if they so wish.

Tasty Treat Troubles!!!

I had some trouble locating some of the ingredients for my Last Meal Recipe as some of the ingredients were somewhat unique. One such example is the vanilla bean. we had to go to several stores before we found it. Fortunately, every other ingredient was simple to find.

Tuesday, October 27, 2015

Mmmm... Tasty

I was searching for some desserts for the Last Meal Project and found a pretty useful site with all kinds of tasty treats WITH RECIPES and I hope people will find this to be helpful.

States of Matter

Today we were refreshed on states of matter and how they apply to Chemistry. I am very comfortable with this particular topic within any field of science. I also feel that I will learn some new facts about matter and how they can be applied to our work.

Holy Moley!!!

      Today I turned in my Mole Project A.K.A. When Moles Fly and I found out that this project was not due until Friday. I was not told this and thought it was due today. I checked to see if this new due date was on schoology, but it was not. So does anyone know where this new due date was found and if so, please let me know so this can be prevented in the future.

Measurement Week 1 Post 1

Unfortunately, I will be unable to participate in the Aspirin Lab as I have failed the Pre-Lab test. However, I can still work this to my advantage. I can study this packet and be prepared for the types of Pre-Lab questions that I will be challenged with.

Atomic Structure And Radioactivity Week 1 Post 2

Today was our weekly quiz. Surprisingly, I felt that I did pretty good, despite getting stuck on a few questions here and there. As I stated in a previous post, I feel that this unit is easier than Nomenclature was and I feel I can use this unit to get my grade back up to a decent level.

Atomic Structure and Radioactivity Week 1 Post 1

Though we were only introduced to it today, I can feel that I will understand finding the amount of protons, electrons, neutrons, etc. much easier than the previous unit.

Post 2 Nomenclature

Whenever we move on, I feel I will need to remember these rules for naming chemical compounds, especially for labs. I will have these memorized by the end of the year, I hope. I will make that a goal for this class, aside from getting a decent grade.

Post 1 Nomenclature

I feel that I struggled getting the hang of naming Type 1 and Type 2 binary compounds. There were so many different rules. However, I felt I did exceptionally well on Type 3 naming as well as naming acids. I also struggled with polyatomic ion naming.

 Conclusion Questions
1.  It is important to correctly identify a plant/root because if you are wrong when using it and if its poisonous, chances are you won’t survive.
2.   It would be helpful to know plants from other regions because the preparation of a specimen may require another type of plant in order for the medicine to be effective.
3.  There is a significant difference if you were traveling in a different season because every plant has its own blooming season, which may not go along with yours.
4.  It would be important to bond with the local people about their plants simply because they know them better than you do.
5.  I would not because there is a chance my source of information may be outdated, be it in text, or my mind.
