Equipments that can be used during the lab are the following:
(Tirrell burner, rubber tubbing, evaporating dish, 4 beakers, filter paper, a funnel, watch glass, scoopula, forceps, glass stirring rod, distilled water, wash bottle, magnet, tape and zip-lock bags.)

Using the above list of equipments, the objective is to separate the mixture (containing sawdust, salt, sand, and iron) into four pure individual components.

I just need the procedure of this science experiment. Please list them out in bullet points, not in paragraph form. Thank you so much for helping!

hi,
so, i know that carboxylic acids don't usually undergo decarboxylation.
now, when beta-keto ester is heated, CO2 is lost. can anyone tell me why this occurs? and what's its importance in organic synthesis... other than being a method for producing methyl ketones.
thank you

from what i understand cold fusion is a theoretical method of attaining a controllable fusion reaction, am i right? but anyway are we ever going to have fusion power plants? would be the cheapest energy ever! (hydrogen fusing to helium is the base of a fusion reaction if i remember rightly?)
