Doing Chemistry

0

Over the year, we’ve done a lot of labs in Chemistry. It is considered an important class probably mainly that it has multiple classes being put together to form Chemistry. Not only is there chemistry work but also math is involved in figuring out problems in molar mass or grams being converted into moles. The main point of this writing is to focus on one aspect, what does it mean to “do chemistry.” From prior experience in labs over the course of the year, I would say doing chemistry would be participating in the labs and doing the labs to see what chemistry truly is and what the outcome of the labs are. In according to the handout our teacher gave us, we’ve done a total of 30 labs over the year. In most of the chemistry concepts, I have successfully mastered, or done correctly, some of these labs didn’t go as well as I thought it would. The math work was kind of confusing in some of the labs I did incorrectly, but as I looked at it closer and thought more, I figured out my mistakes and went on to master the labs. Not only have I learned from in the lab, but also outside in lectures, textbooks, and other readings that our teacher gave out to the class. All in which helped to aid our understandings of chemistry theories and concepts. Chemistry is mostly related to the doing of not only labs, but homework, tests, quizzes, classwork and taking notes which helps you do chemistry in the labs. All of the above is really good preparation for the labs so you know what you are doing while you are doing the labs and you need to know if you are doing the labs correctly. Doing chemistry is doing all the work that is chemistry related like most of the labs we did were all including different chemicals with different mols and grams and had different reactions to different solutions. While you’re doing chemistry you must wear safety goggles and listen to the teacher or instructor in order to do chemistry correctly so all your data and information is accurate to the actual results. Chem was a good learning experience this year, doing labs with different chemicals was fun and interesting to see what would happen. It wasn’t all about results and tests, we had fun too. A few days ago we lit our hands on fire with some chemical and we put bubbles on our hands and lit them up in our hands which was really cool. It didn’t even burn my hand when I did it which is why chemistry is so interesting. We also blew up a lot of things which was probably the coolest part of chemistry I liked seeing things being blown up especially using chemicals it made it more loud and more science related. Doing chemistry is about everything we do in chemistry. It was a great experience to do. Saucepan 3000

This article is about a new dinosaur fossil that has been discovered in China that was a meat-eating dinosaur from the late Jurassic period that was less than a year old. James Clark made the discovery.

Soap Making Lab Abstract

0

We made soap last week in chemistry in a “Saponification Lab.” 

SOAP-MAKING LAB

Materials

Apparatus

50 mL of olive oil

  • 50 and 10 mL graduated cylinders to measure oils
  • 400 mL beaker

45 mL of coconut oil

10 mL of castor or avocado oil

50 mL of Crisco

Water:  38 mL (if using avocado oil) or 51 mL (if using castor oil)

  • 50 mL graduated cylinder to measure water

NaOH:  19 g (if using avocado oil) or 21 g (if using castor oil)

1 g sugar

essential oil (optional)

NaCl (if necessary)

  • Weigh boat for massing NaOH
  • 250 mL erlenmeyer flask for mixing water and lye
  • Glass rod for stirring
  • Stirring magnet and magnetic stirring plate (if available)
  • Handheld emulsifier (if available)

 

  • plastic cup for setting soap

In this lab, we had to make soap out of different types of oils and sugar and water. Once we were done, now we have to  wait  for  the soap to mold and let it lose its alkalinity.

What I think about gases

0

I’ve learned a lot about gases from the start of chemistry and all of the gases we have used in labs to find out solutions. I think gases are pretty cool because we can use them to explode stuff which is pretty saucy. I never knew that there were types of gases you use for chemistry to perform different experiments and solve questions by finding the solutions to the problems. I always thought gases were the ones that come out of a car or a persons bumbum. And I always thought that gases had different or multiple colors and smelled different which sometimes they do but not all the time. But now, I think they are pretty complex and cool and fun to do experiments with. I like blowing stuff up and since we can do so with these gases it makes me happy.

Independence and Critical Thinking Questions

0

Gas has existed since the beginning of time oftentimes, it was referred to as “oxygen;” But, in the late 18th century, “air” became known as gas, and people  were able to distinguish between different types of gas. Towards the end of the 18th century, scientists started testing and developing laws that later became known as the “gas laws.” These laws describe properties of gases, and how they react in different situations.

Gases help me live my life errrrrrrrr day.

The kinetic molecular theory account  observes good behavior in all different kinds of states of matter and gases

Gases can be changed to a liquid or solid if the temperature is too low or the pressure is too high.  As an example steam changes to a liquid when it touches a cold object, and nitrogen gas can be converted to liquid nitrogen by compressing it to very high pressures.

Ice Melt Lab

0

During Chemistry, my partner and I were told to melt ice. The ice first starting off in a solid form at its freezing point. In a total of 10 minutes the ice reached its boiling point and became a liquid undergoing a physical change. In my graph, like I said it took us 10 minutes to reach its boiling point. Every 30 seconds it seemed to have gone up 11 degrees Celsius. The ice reached its boiling point at 6 minutes and 30 seconds but we were told to wait as the boiling took 3 more minutes and 30 more seconds to have a straight line of continuous data of 100 degrees Celsius to complete the graph. The ice was releasing heat during this process which caused it to melt and if the Ice refroze it would have to gather that heat again to recreate a solid form – Saucepan

Law Of Conservation Of Mass Lab

0

In this Lab we learned how that the mass of substances should be conserved even when the substances shape or form go through a chemical change.

In Activity 1:  When me and my lab partner mixed the solutions, the form of the substance changed. For us, the mas didn’t specifically change if it did it was not of a great proportion.

In Activity 2: When the baking soda and the vinegar was mixed into the plastic bag, the solution fizzed up and the bag expanded in size. The mass did not change in this activity when the baking soda was added and our bag did not open or blow up so the mass didn’t change at all.

In Activity 3: Heating the steel wool over the bunsen burner made its color change from a dark blue to a blackish color, and after that the the wool looked burnt. We were pretty careful during our activities in none of them our mass changed so in that part I think we did that correctly. Keep it saucy
