Learning Gas Formulas

The main formula for solving gas laws is nothing too complicated. I actually found it quite reasonable. You can easily see all the relation ships and the explanation is very simple. The next steps are understanding different forms of the equation.

Phase Changing Graphs

I would say the easiest thing in Energy and Phase Changes would be interpreting the graphs. I always enjoyed a visual to my problems and seeing the relations ships in different atmospheric pressures is really cool. I also find it interesting that at certain atmospheric pressures certain phases are not possible.

Phase Changes

This unit is extremely easy to deal with especially because of how much common sense it implies. Its pretty easy to understand how much energy it takes and why things don't change when they do because of phase changes.

Gas Test Review

To study for this upcoming test I studied a lot of the 3 gas laws. I have gotten to the point where I am easily able to recognize what I need to solve and understand what I am being told. This should help a lot with how long it takes to complete the test and me accuracy too.

Air Bag Lab

In this lab we had to calculate the amount of vinegar and baking soda needed to fill a plastic bag enough that you couldn't pinch the middle. The vinegar and baking soda reaction you can remember from grade school days. I ended up not betting to do it because I didn't have my procedure ready.

Winning the Boat Race!

I have always lagged behind in chemistry because I am not so good with things on paper, however, when I herd that we had to design a boat I was ecstatic. I immediately got into the project. I didn't make our boat before class so I had to work with what we had in class. I ended up using the tinfoil pan and just attaching our motor to it. In 5 minutes our boat already made it down the lane. So all I did was cut off as much as possible and we ended up being one of the fastest boats!

Creating Bio-Diesel

Making the Bio-Diesel was actually a lot easier than I expected. Following the steps was a breeze, however, we had problems with turning up the temp on the Bunsen burner way too much. We also took a little longer than others which was a downer. In the end however we got our fuel made with no problems and finished the lab.

Bio-diesel Video Project

This project really sounded fun in the beginning, and I was extremely enthusiastic about making a music video. However, as we began to actually record the song, so many small hicups really made the stress get to me. Our eventual final project was pretty embarrassing and I was pretty burnt out, but at least my guitar playing was on par. I think that the project overall was interesting and fun, but I do wish I did better on the video.

Bonding Practice

Practicing what you need for the test is hard but needed. I like to go through all my notes and make sure I feel like I already know what it says. I also like to watch videos and read stuff online. So here is a few links that helped me.

Bonding Basics

The type of bonds we are learning about remind me of the type of stuff we learned about our freshmen year, so it is kinda fun picking it back up again. Its also pretty easy because of how its like riding a bike as the rules and processes come back to you.

Bonding Lessons

I really stinks when you are absent for 90% percent of a unit and have to catch up in 3 days, but I am still alive today so its not impossible. Working on these questions felt a lot like memorizing vocab because of the way I had to remember different structures and types of bonds.

Periodic Trends

Periodic Trends: Atomic size gets larger as you move down a group and smaller as you move left.

Trends in Ionization Energy: The energy needed to remove an election from a gaseous atom. Ionization energy increases as you move up ant to the right across the periodic table. Metals naturally give away electrons, so their ionization energy is low.

Trends in Electronic Affinity: The ease in which and electron may be added to an atom, forming an anion. Some atoms don't require energy for this to happen, and actually give off energy, which is why some electron affinities are negative. Electron affinity increases as you move up and to the right.

Trends in Electronegativity: Tendency of an atom to draw electrons toward itself when chemically combined with another element. There are no units for electronegativity. Electronegativity increases as you move up and to the right across a period.

Spectroscopic Analysis of Co and Cu

In this lab some of my classmates were able to analyze solutions of both cobalt and copper to compare their absorbency and transparency. I heard it was super simple so I wasn't too sad about not being able to participate. Luckily we still got the data so in the end we were still able to participate quite a bit.

Electron Configuration

The Four different levels on the periodic table

-Principal Energy Levels: describe how far away from the nucleus an electron can be found. In other words the one with the most distant orbital electron.

-Sublevel: There are 4 sublevels s, p, d, f,

-Orbitals: The s sublevel contains only one orbital. (Spherical shape) p sublevel contains three orbitals. (Dumbbell shape) d sublevel contains five sublevel and f contains seven orbitals (Complex shape)

-Spin: every two electrons spin in opposite directions.

Wavelength and Speed

In class we learned that the electronic structure of an atom refers to the arrangement of electrons. We also learned that visible light is actually a form of radiant energy. Electro magnetic wave is characterized by its wave nature. All waves have a characteristic wavelength and amplitude. The frequency of a wave is the number of times. The speed of a wave is given by its wavelength times its frequency. The electromagnetic spectrum is a display of various types of electromagnetic radiation arranged in an order of increasing wavelength. This is just some of the stuff I learned about.

Flame Test Lab

This lab was meant to test and see what color each metal would burn, It was super fun of course because we got to use fire! However I fell quite a bit behind everyone else because I was not as prepared as I needed to be. I didn't have my data sheet made so I was not in a good position to start. I eventually got it figured out and everything turned out well so I figured I shouldn't stress about it. I hope everyone else enjoyed the lab as much as I did.

Fireworks

When we began learning about fireworks in chemistry I was fairly intrigued because it was something that I wouldn't mind knowing a little more about. It was surprising to find out how there were 2 stages in which fireworks explode. Their first stage is the launch in which the explosion creates enough air pressure to launch the bulb very high in the air. Once this bulb is high enough it then has a second charge that explodes igniting the colors and dispersing the stars. We learned that different color stars are achieved by adding different metals that are burned. Also depending on the mixtures different hues and flares can be achieved.
