How Can You Accurately Separate and Quantify Components in a Mixed Sample Lab?

AI Thread Summary
The lab involves separating and quantifying components in a mixture of sodium chloride, silicon dioxide, iron filings, and calcium carbonate to determine their percent by mass. Key separation techniques include filtration, evaporation, chromatography, distillation, centrifugation, and sedimentation. Sodium chloride can be dissolved in water for separation, while iron filings can be extracted using a magnet, and calcium carbonate can be reacted with hydrochloric acid. The availability of hydrochloric acid and magnets for the lab is uncertain. The discussion seeks confirmation on the appropriateness of these methods and whether there are more efficient alternatives.

Homework Statement



In this lab we are going to be given a mixture containing sodium chloride [NaCl], silicon dioxide [SiO2], Iron filings [Fe], and calcium carbonate [CaCO3]
The goal of the lab is to use separation and measurement techniques to determine the percent by mass of each specie in the original sample

Homework Equations



The lab book gives a list of methods of separation that I suppose are what we should resort to using in the lab
These methods are Filtration, Evaporation, Chromatography, Distillation, Centrifugation, and Sedimentation
In addition
NaCl is the only soluble compound
Fe is the only magnetic substance
CaCO3 exclusively reacts with HCl
CaCO3 + 2HCl -> CaCl2 + CO2 + H2O
I am not sure if we will be given HCl or a magnet though

The Attempt at a Solution



Since the NaCl is the only soluble compound we can dissolve it in water, remove the other precipitants, and evaporate the water to determine its mass
I don't know if HCl or magnets will be provided or allowed for use but I think they can be used to determine the amount of CaCO3 and Fe respectively
I just have a feeling that the methods in the lab book listed above are the ones that we are supposed to use so is there any easier and more precise method to separate the species?

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...
