Solving Reaction Rates in Lab Experiments

AI Thread Summary
The discussion revolves around calculating the concentrations of reactants in a lab experiment on reaction rates. The user is tasked with determining the concentrations of KI, (NH4)2S2O8, and Na2S2O3 after mixing solutions A and B, with a total volume of 20.0 mL. They are considering using the dilution equation M1V1=M2V2 to solve the problem but are unsure how to set it up correctly. The conversation emphasizes the need to assign volumes and known concentrations to variables for accurate calculations. Understanding and applying the dilution equation is crucial for solving the reaction rate experiment effectively.

Homework Statement



okay so I am going to do a lab on reaction rates, there's a table given (effects of varying concentration)

there are 9 reactions, I will just give one, ( if i can figure this out ill figure out the rest on my own)

so reaction #1 flask A contains 7.50mL of .200M KI
none of .20 M KCI
.0050 M S2O3^-2
1 drop of starch
flask B contains 7.5 mL of .100M S2O8^-2

It says for each reaction determine the concentration of KI, (NH4)2S2O8, and Na2S2O3 that will be present when solution A and B are mixed together. the total volume for each reaction is 20.0 mL.

Homework Equations



M1V1=M2V2 ?

The Attempt at a Solution



I'm not sure how to begin this, would I have to use the M1V1=M2V2 ? how would I set it up ?

Correct dillution equation (that's just mass balance) now you have to assign volumes and known concentration to symbols.

Thread 'Confusion regarding a chemical kinetics problem'

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
