Flame Test Lab

The flame test went rather well there were many pretty colors and I learned a lot about light as a wave, an emission of energy. The lab was really cool.

R.I.P. my chem grade

Wow that test was rough. Granted, I didn't have as much time to prepare for it compared to previous tests, but looking back I should have made time. I guess it's come back time. Hopefully the next unit is easier. Hopefully.

Stressed Out

Tomorrows the test and I have little time to prepare. We'll see what happens tomorrow

A few useful links

Just a few quick links, hopefully they help

Crystal pine tree

Not so much to do with class but in chem club we made Crystal Christmas trees. I'm really happy with how mine turned out.

Titrations

We just learned about titration problems and, I'll be honest, they are long and rather confusing. I hope I get to learning them before the test. Here's a few videos I found that might help

Whoops

Today was a practice day for the lab. Our titrations turned out really pink. Hopefully we can do better for the real lab.

pH and Logs

We just started the new lesson and so far it's been ok but we just got to molarity to pH conversion.
This meant that we are utilizing logarithms. It's not difficult but it's not the most pleasant thing in the world. However this video will hopefully save me. :)

When scrounging on the internet

I found a few more links while on the internet. Not the most useful, granted, but still worth mentioning.

Quizzes

Quizzes just came in. I'm off to decent start but from rumors I hear this quarter will be difficult. So far it's been ok but we shall see what happens... I guess

Murder Lab

A few days ago, we did a simulation of a murder case in which we utilized our knowledge of dilutions and chemical reactions to solve the mystery. Lab report is due on Tuesday. I'm excited to see if we're right but also terrified.

Dilution of Food Colouring

Today we did a dilution activity with food colouring and it was tremendously useful in understanding dilution problems. Quiz is on Monday and I am nervous about it since it's covering topics from last semester.

Last day of lab

Today in lab we wrapped up loose ends by weighing our copper and working on the equations linked with this project. Overall I found the lab to be a great hands-on experience with what we learned in class.

More pics from lab

Second day of lab where we removed the nail and any liquids from the copper. Now we just need to wait for it to dry.

Amazing Way to do Stoichiometry

Marie found this online and showed it to everyone and I just figured I would spread the news. The method is called the Magic Number Method and it is a great way to check your work since the process is twice as fast as doing Stoichiometry the regular way. Absolutely brilliant!!

Iron chloride lab

Just started a 3 day lab and it's going well

Why didn't i find this earlier

Just searching around on Google and found this pic for solubility rules. Wish I had it for the test but at least I have it for the final.

The Labs

Here's a few pics from the two land we did for this unit. I really enjoyed these labs as they showed that chemical reactions actually happen and they are not just on paper

Feeling Ok after the test

I've heard from a lot of people that the test was really easy for them. That they were really confident with the test, I however wasn't so comfortable on the test. I had trouble getting in the groove of the test but at least it's over now so... I guess that's a plus.

Anyways,
