AI Thread Summary
To prepare a 100 mL solution of 0.00200 M NaCl from a 0.500 M stock solution, first calculate the required volume of the stock solution using the dilution formula (C1V1 = C2V2). This results in needing 0.4 mL of the 0.500 M NaCl stock solution. Use a 1-mL volumetric pipette to accurately measure this volume and transfer it to a 100-mL volumetric flask. Then, add distilled water to the flask until the total volume reaches the 100 mL mark. Finally, mix the solution thoroughly to ensure uniform concentration.

Hello, this is my first post on this forum.

I'm doing a prelab and the question asks:
Explain in details how you would prepare 100 mL of a 0.00200 M solution of NaCl by diluting 0.500M stock solution. The only glassware available for you to use are 1-mL, 5-mL, and 10-mL volumetric pipets and 100-mL volumetric flask.

I'm not sure what exactly I should explain. If someone could guide me through this, thanks in advance.

List steps - like taking a sample (what volume?) with a volumetric pipette, transferring it to a flask, filling up with water to the mark.

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...
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...
