Airbag Lab

We were given the challenge to make a theoretical airbag with a bag, vinegar, and baking soda. It is tricky because we will need to use just the right amount of vinegar and baking soda to inflate the bag to the right amount... Not too little and not too much. To do this we had to find the volume of the random bag given to us. To do this, we filled the bag with water and poured it into a graduated cylinder to obtain an exact volume. After this we could use some of the gas law formulas to calculate the mols of CO2 needed to inflate the bag. 

I had a fairly small bag and needed about .01 mols of CO2.. So about .87 grams of baking soda and 15mL of vinegar. 

The experiment went well and I was able to pass the lab by inflating the bag to the right amount. Here is a photo of what the experiment looked like.

Post Gas Law Quiz

Another doozy thrown at us by Mrs. Frank. Going into the quiz, I felt pretty confident and felt like I knew the material well enough. Once I started the quiz I immediately started questioning myself on the conceptual questions given to us. They were tricky and maybe a little more reading from the book would've helped. All is well though, moving on mentally to the test. Need to do well!

Avagadro's and Combined Laws

Avagadro's Law is another law that we just recently learned. It is a little more complicated to work out mathematically but it makes sense if you think about it. It is the relationship between the mols of a gas and the volume of it: V1/n1=V2/n2(n=mols). Here is a photo explaining the relationship in visual terms.

The next law we learned is the Combined Laws. This essentially combines all the laws we have learned and puts it into one fat equation. It is getting more complicated because there is a lot of information that needs to be taken out of a problem and filtered. Here is a photo with more details.

Boyle's and Charle's Law

Our new unit is Gas Laws. So far we have learned a few of the gas laws and I'd like to reflect on the first couple. The first is Boyle's Law, he discovered the relationship gases share between volume and pressure. The equation is simply P1V1=P2V2. It is a simple proportion that makes sense when you think about it. Here is a simple photo to explain the relationship.

The next law we learned about is Charles' Law. Charles' Law shows the relationship that Temperature and Volume share: V1/T1=V2/T2. It is also simple to think about, When something is heated their particles get more excited and thus their volume is increased. Here is another photo that explains it simply.

Post Energy Test

The test wasn't terrible for me. It was skeptical because we were given 30 minutes to do 22 question over the unit and it counted as 100 points. So you were given very little wiggle room with the amount of questions you could miss. The practice tests Frank put on schoology really helped, the format of the questions were pulled directly from that. In the end, I was able to pull off an A which was huge to my quarter grade.

Biodiesel Boat

We were given the opportunity to use our biodiesel to run our put-put boats. It was an exciting event because we actually got to make a boat and race it against others. After a tedious 10 minutes of construction, Kyle and I created a boat out of a gallon jug. We raced it and got a pretty average time, but we made it across the finish line, meaning we get full credit. In the end, I thought this was a needed change of pace for this class. It was an enjoyable break and it took some stress of of my senioritis that is kicking in pretty hard. Anyway.. I didn't actually get a picture of our boat, but here is a cool put-put boat :-)

Biodiesel Lab

We started our biodiesel lab a couple weeks ago, and I have to say it was one of the more fun things we have done. It started off with the video that I discussed earlier in the week. Then we actually got to make our biodiesel. It was honestly an easy process and makes me wonder why we don't use biodiesel... Anyway, it ended up eating through our cups and we had to throw it away :/...

Biodiesel Project

We have worked on a bio-diesel video for the last week. Kyle and I made out project to increase awareness on how bio-diesel can help the environment. We used some pathos to get to the viewer. We compared the poor effects of oil to the benefits of bio-diesel.

Pancake Party

The pancake party was a nice break. It was a great time with a lot of fun and laughs. Frank the Tank made some delightful pancakes and we had plenty of tasty toppings. Frank also made an attempt to create some geometrical shape with the pancake batter.. The image is still up for debate on what it actually looks like..

Bonding Post Test

The bonding test was quite difficult for me. I was not entirely prepared because the previous weekend and a few of my weekdays were spent at DECA state and I was not able to refresh or review until I got home. Hopefully I can work hard to get my grade back up.

Post Electronic Structure Test

The Electronic Structure Test... It is a step down from last unit so I was hoping for a somewhat easier test in comparison. The test was 50 questions which is a little overwhelming because we don't have the longest time in the world to finish the test. I thought it was a very detailed test that could easily trick you. A lot of the units could've thrown you off and a lot of the little wording about shells and structure too. All in all I am hoping for a decent grade, even if I do miss a few simple ones, there was room for error. On to the next unit!

Quiz Results

I received the results and I was pleased! I use my quiz results to help me determine how much I know about the chapter. This means I will hopefully do well on the test because we only added one more lesson to the chapter after the quiz. All is well in the chem world, we are continuing to grind to the end.

Spec 20 Lab

This lab was a very tedious lab. We had to measure the amount of light passing through a certain solution in a very expensive machine. The machine was able to tell us the amount of light being absorbed into the solution and the light passing through. I have not written the lab report and I will get back to you with results in the end.

The very expensive machine

Post Electronic Structure Quiz

Going into the quiz I felt pretty good. I did all of the practice quizzes and felt comfortable about the real quiz that was awaiting us on Friday. Going into it knowing it was 35 questions felt good. It allows a little room for error if there are a couple tricky ones. The actual quiz was somewhat tricky. The questions seemed to be very easy, except there was a lot of detail that you needed to pay attention too because it could've easily tricked you. All in all, I thought the quiz was okay. Hopefully the score reflects my thoughts.

Lessons on Electronic Structure

The first couple of lessons of this unit aren't as bad as a lot of other units we have had. The first lesson was primarily math. All we had to do was plug and chug with a couple equations that have to do with wavelength and frequency. Then we moved on to a little more complex stuff that involves electron orbitals. So far so good though, hopefully this unit will help me get back into the rhythm of chemistry.


Here is the wavelength equation:

Overall Summary of Acids and Bases

Overall, it was a difficult, yet interesting unit. I personally was gone two days for field trips and those days were on the lab days. This was a good and bad thing. Good because I didn't miss any lessons, and bad because there was 3 questions from the lab we performed. Oh wells... Everything that was said about acids and bases was somewhat true. It was a difficult unit but I gave it my best effort. It was a good run Acids and Bases.....

Post Acid Bases Test

After I put my pencil down and turned it in, I was a little frazzled. All the stories told about the "worst chapter in the book" were true. It was a difficult chapter, not because the material was difficult to understand, but because of all the possible tiny mistakes you can make during the test/unit. The test for me could've gone either way.. Hopefully all is well and there is no sadness in the end of the day.

Acids and Bases Titration Lab 2

The titration lab 2 is very similar to the last lab. Most people had to standardize the new solution but luckily we didn't have to because we already figured out the molarity in the last lab. This helped speed up the lab. Essentially we needed to find the molar mass of the unknown substance we had. We titrated the solution with the NaOH solution with the known molarity. We could then run the math and calculate the molar mass of the unknown substance. I thought this was a good experience because I missed the first day. This was complicated lab but I definitely needed it to help me get through this unit.

Acid Base Titration Lab 1

Last week on Wednesday through Friday we worked on a titration lab. It was one of the more complex labs we have done in the year and I missed it because I was on a field trip. So basically, we titrated KHP with NaOH. We used the mass of KHP and the volume of NaOH to calculate the molarity of the NaOH using the volume needed to titrate the solution. Since I was gone, I used another groups data which had 0.1930 as the Molarity of the solution. Part two of the lab consisted of us titrating acetic acid with the NaOH we had. Since we now know the molarity all we needed was to know was the volume of NaOH is needed to titrate the vinegar. The group's calculations came out to about 0.2318M for the Acetic Acid.

In the end, I do believe it was beneficial to do this lab because it would've helped me understand the unit more. Since I missed it, I am spending my time trying to learn what happened. Luckily we do another lab that is very similar Monday and Tuesday.

Acid Base Quiz

So I've been convinced that the acid base unit is the most impossible thing in the world. Since I am somewhat scared I am trying to prepare myself a little more than I normally would. I prepared pretty well for the quiz so I was hoping for the best... I ended up with a B on the quiz so I was somewhat okay with it but I was hoping for better. Oh well, on to the test!

Test

The Aqueous Solutions Test was not the worst test in the world. It was 26 questions so it was decently short and it was relatively easy compared to other test I have taken in the past. Only struggled on some of the ions.. Those confused me through the unit. Hope everyone did well!

Mystery Murder Lab

Over the past couple of days we have performed a lab that told us to find out who killed Miss Scarlet. We were left a series of clues and essentially told to figure it out. In the end, we were able to test a mystery substance that we believe killed Miss Scarlet. We needed to test the substance to find out the molarity, which would then lead us to the killer. It was a creative approach to the what would've been average lab! I enjoyed it thoroughly. Here are some photos of our reaction and finished product.

I am currently working on the math to get the result and I will post them shortly!

Dilution Lab and Lesson

We learned a lesson about serial dilution today and learned the math behind diluting solutions. It consists of a simple equation which essentially describes a ratio.

We performed the lab with simple food coloring and we diluted the entire solution down to clear water. Although the lesson was simple the experiment helped me get a full understanding of the lesson. Hopefully I will be ready for the quiz on Monday! 

This is what the experiment essentially looked like in animated terms.
