Combustion

I learned that Combustion is mainly fire!

The diagram stood out the most to me because it was a visual aid to help me understand this standard.

I was confused by what the activation enegy was suppose to be and do.

I want to know about activation energy.

Stoichiometry

15. Stoichiometry

I learned that all equation are not balanced.

The stoichiometry diagram

The math and how to balance equations. 

How to do the math for stoichiometry.

Synthesis & Decomposition

1. I learned how to balance equations
2. The lab where we had to neutralize the substance by using our breath.
3. I am a little confused on what synthesis and decomposition is.
4. I want to learn about the distinction between synethesis and decomposition.

Gases

What did you learn?
- I learned that you can find the pressure, volume, mole and temperature of anything with the PV=nRT formula.

What stood out to you the most in this standard?
- The demo of the soda can stood out the most because it was a visual of what the topic consisted of.

What things totally confused you?
-The idea of the pressure on the inside of something and on the outside which is greater and how can you determine what the pressure is. And finding the partial of anything.

What do you want to learn more about?
- Finding the partial air pressure or water vapor.

Marshmallow Calorimetry

I learned that you can burn all the energy out of a marshmallows and that you can calculate the heat change by using water. I proved that a energy can be burned out of a substance. It shows how we burn calories when we eat and then exercise to burn calories.

Extension
You can calculate the amount of ice that has melted from the heat that emerges from the burning marshmallow.

Thermal Energy

The Metal Block is colder because of its heat capacity.

The thermal energy is released from the metal to the ice causing it to melt fast.

Extension

The Sun warms the earth through heat waves, UV rays, radiation, and most importantly vision rays.

Heating Curves

I learned there are different changes to the heating curves based on the heat and the pressure which is measured in (atm)

It results to show that every item has a different heating curve.

When touching a piece of metal and a piece of wood that has the same temperature the thermal energy in the metal is released to our hand making it seem colder.

Extension
~The cooling curve would be the total opposite of the heating curve.

Intermolecule Forces and Physical Properties

I believe that this two subjects have been the hardest for me to understand by far I like how we did the chemical zoo by seeing examples and presentations done by other study but however; I was confused on VSEPR know what its purpose was and how its used left me puzzled. Intermolecular forces were a little bit better at understanding but still had confusing I learned that water is one of the stronger intermolecular forces.

Covalent Bonds

I learned that there are two different types of bonding that is important in chemistry. Covalent and Ionic bonds are the two different types we learned bout.

 It important that we learn this because to make nonmetal compounds you have to know your restrictions and how its suppose to be written.

I liked having the Bonding Practice it was helpful.

I found the drawing of the Lewis Structure difficult because I'm not sure when to use a double bond or when you don't have enough electrons to satisfy the elements to fill its outer shell.

Id like to know how to correctly write how the Lewis Structure is suppose to be drawn.

Ionic Compounds

I learned that can be many different compound made between 2 or more elements.

Its important we learn this to know how the compound interact with each such as NaCl= Sodium Chloride= Salt.

I like the tutorial where we read the explanation and did practice problem but were still able to check ourselves.

I found the transition metels and the polyatomic bonds a bit confusing do to the fact of not know what needs to be crossed over and what does not need a subscript.

I would like to learn more about the transition metals and how the are suppose to be used when making Ionic Compounds.

Periodic Trends

I learned that Periodic Trends can be classified with electronegativity and ionization energy. All using the number of valance electrons are in the outermost energy level.

It was important because you can tell in the elements setup whether or not its an reactive substance.

I like the sodium and water experiment you should the class, it was very interesting.

I found the way your suppose to order the elements by its ionization energy and electronegativity very confusing.

I'd like to learn more about what elements have a lower ionization energy and how/ what it reacts with.

The Electron Cloud

The Electron Cloud

        I learned that electrons own there own clouds and they orbit in different energy levels around the nucleus. I also got the concept of the periodic tables and how it contributes to the electron cloud model.

Its important because it shows where energy is emitted and aborsbed.

I like the electron configuration.

How to calculate the electron configuration using the periodic table. 

How to use the periodic table and find the electron configuration. 

Part Three- Bohr Model

What I learned from this standard was that different colors have different engery levels. Red being the lowest and violet being the highest. You can tell which color has the most energy by look at the wavelength which is the distance between each crest. The closer the crest are together the more engery is being sent out and the further apart the wavelengths are the energy decreases.

Its important that we learned about the Bohr Model because it shows why the colors in the rainbow are where they are and what colors are real and fake. Also, the Bohr Model helps you understand how many photons are given off through the electron when jumping from one energy level to the next.

I like the math part of understanding the Bohr Model, using the equation given to us in class. The equation helped us find out what the electron voltage of the wavelengths.

I found the emission spectra and which way emission and absorption levels go a bit confusing. I didnt understand the point of the emission spectra and what the energy level had to do with each color.

I wouldn't mind just review what I was confused about.

Chemistry 101- Part Two

What I learned?

•          I learned the difference between fusion and Fission, which fusion combines and fission seperates.
• I learned what Nuclear decay was and half-life, and how to calculate alpha and beta. 

Why is it Important? 

• Its important because we can use the alpha and beta to discover new elements. 
• Fusion and Fission is important because you combine atoms and make atoms small to make useful.

I liked...

• Calculating the alpha and beta to find a certain element, and the Gizmos that show a visual of what we need to comprehend. 

Head-Scratchers..

• I had a hard time finding the age after you found the percantage. 

Learning more..

• What are elements can be created using alpha and beta.

Learning New Things

So far in Chemistry I've learned about the Atomic Structure, which is composed of what an atom is, what does it look like, and what an atom consist of. We've also learned about different elements on the periodic table, what are metals, non-metals, and metalloids. 

Importance

I found the importance of the two objectives was to find it purpose, and what we us it for in our everyday life. 

Likes and Confusion

I personally like learning about the atomic structure because it somewhat had to do with numbers and I like math. I found the abundance of nature difficult to understand even though I passed my quiz; I wasn't 100% on the specific topic. 

More To Come

I would like to learn more about different chemical reaction, just for the fact of my career consisting of working with different medicines in the medical field.
