Hello and welcome to BrimChem. My name is Kevin Brimage. I have over 20 years of high school teaching experience mostly teaching Chemistry and Physics. I taught a couple of year in North Carolina. I spent almost 20 years in the Dallas area at The Colony High School and Coppell High School. I am currently teaching at Caddo Magnet High School in Shreveport, Louisiana. My channel is designed to aid my students. I have many videos covering more advanced topics in my IB section. These would be appropriate for IB and AP chemistry students. I also a collection for Regular and Honor's level classes. Enjoy and let me know if they help.

i luv u so much thank you for explaining what my teach couldn’t
Thank you
Nicely explained
Great video! Do you by any chance know of somewhere I could find an extended activity series?
This is such a late comment and you’re probably already out of the course… but you can probably just find it on safari. BUT, teachers generally just use the elements that are on the activity series on tests and quizzes.
a topic my teacher couldn't teach me in two weeks, you explained in 6 minutes THANK YOU
Omg thank you so much for this! This saved me on my test!
Hi its me
i wish you were my teacher
Glad I could help.
kevin thank you. because of this video i will be passing my chem test tomorrow
Great! Glad it helped.
old but extremely helpful.
What if both of the things are the same temperature? which one goes where?
Since heat energy always moves from the object with more energy to the object with less energy, if both objects are the same temperature there is no net heat flow. So nothing happens.
Sir why take concentration of A, at high.I didn't understand.Please tell.
It is not required. You may take the concentration at any point. BUT, when you determine the reaction rate of a reaction, it is normally determined as the “initial reaction rate”. That is why you take the starting concentration.
@@BrimChem Sir in graph of chemical kinetics, concentration of reactant taken at high point but concentration of product taken at zero point. I didn't understand that logic. Please tell me.
Taken at time = 0
@@BrimChem and concentration of reactant,, taken time =?
PMT Academy Review the video at the 5:00 -6:00 minute mark. You want the initial concentration, which is the concentration at the beginning of the reaction.
How will you know which element to compare the lone element to? For example in the first equation, how will you know that you will compare lithium to aluminum and not SO4?
Ella Gutierrez you compare it Aluminum because Lithium and Aluminum are both metals. A metal must replace another metal in the compound.
Are you referring here to average rate (multiple experiments carried out determining average rate at different concentrations) or instantaneous rate (one experiment measuring instantaneous rates as concentration changes)?
John O'Reilly Works for both.
You're doing it wrong because you aren't balancing the chemical equations.
Kaptain Kush Yes, you are correct the equations do need to be balanced as I state at the end of the video. This video was on how to know IF a single replacement reaction occurs.
Didn't watch until the end, however, you should still balance them as it can be confusing to viewers. Nonetheless it was still a good and helpful video.
Glad it helped.
Bless your soul!
Haha, I guess it helped.
Thank you! This video helped me a lot! You are really good at explaining !
Very helpful! Thanks
thanks
Extremely helpful. Thank you very much.
Great Video. Many thanks!
I finally get it
Glad it helped.
I have an exam on tuesday and I've been having a problem with 1 problem. If I have steam mixed with 1kg of ice to produce water at 20 degrees... would I put it as -Qv -Qwater from 100 to 20 = Qf + Qwater from 0 to 20? Or would the Qv not be negative? I'm trying to find the mass of the steam, but the answer is supposedly .1609 kg and by doing this, i'm getting the wrong answer. could you tell me what i'm doing wrong?
Kevin Brimage Thanks a lot!
Glad it helped.
Thanks for the informative video, helped me a lot through studying for exams :)
Yay
