DOUBLE DOWN!

Kay so this is a double blog post, cause I thought someone else posted but they didn't and then some things happened, it involved some elephant and a penguin... but I digress. Anyways, don't mind my memory lapse and this late blog.

On Thursday we were taught how to do average rate, you know
Rate = [(final concentration of A) - (initial concentration of A)] / [(final time) - (initial time)]

In other words:
Rate = [A]f - [A]i / Tf - Ti

Or in other words besides that:

Rate = Δ[A] / ΔT

We also learned about instantaneous rate: The rate at a specific time. The example is shown on page 12 and is answered in steps on page 13.

** by the way - the use of [A] can be replaces by any other variable [B], [C], [...]


We also went over:

On Friday (April 9th) We learned about Rate and Stoichiometry. The example on page 14 shows:
2NO2(g) -> 2NO(g) + O2(g)

We gave 2NO2(g) the value of 4g/min To find out the values of 2NO(g) and O2(g) we use ratios. 2NO2(g) and 2NO(g) have a ration of 2:2 or 1:1 so they have the same value, however O2(g) has a different concentration or ratio of 2:1 so it's 1/2 the amount of 2NO2(g) so it has 2g/min... get it?

We also created / answered some questions on Reaction Rate graphs. (Chapter 18 Worksheet)
(Sorry picture was too blurry... just google it or do your work :D !)

We also did all of the questions on page 15
Received Chapter 18 Worksheet or Reaction Rates Worksheet
Answered Questions 4 and 5 on Kinetics Assignment #1
Was assigned and corrected Questions 1-7 in Kinetics Assignment #2

** AND I THINK WE HAVE A CHEM TEST TOMORROW (April 12) ... I MAY BE WRONG AND IT MAY BE ON WEDNESDAY! ... SO YEAH! **

Yeapp, that's pretty much it... I think I mixed up some events that occurred on those days, but ... whatever they're bound to happen ha. Now a parting gift:


The KFC Double Down - Inspired the post.


Next scriibe is HYCharang :P
