What is IR spectroscopy and what is it used for? What is coherent scattering? What is a crucible? What is water? What is corrosion? What is the vibrational wavenumber for helium? Explain how you got this answer. What are greenhouse gases? What do they do? Are they good or are they ba...
A quartz crucible is a type of cup or bowl shaped container that is made from quartz glass. The main situations in which a quartz...
Once cool, the crucible is re-weighed (the difference gives the sample water content) The muffle furnace is then set to the desired temperature and the sample is ignited for the necessary length of time Once cool, the crucible is weighed again. The difference between this weight and the dry...
What is a crucible? What can be the source of error in titration? Why do we add liquid above the calibration mark when using a pipette? What does it mean if your conventional calibration curve intersects with the concentration axis in the negative direction? What is HOHOC6H6CH2CHNH2? What ...

s historical focus on pure substances – on purifying and characterising bulk compounds. But chemistry really comes into its own in mixtures – including the incredible, organised complexity of the cell. The molecule is a necessary construct for analysis, but loses some of its precision in the ...
in different molecules: as theoretical chemist and Qtaim advocate Paul Popelier puts it, ‘There are millions of carbon (molecular) atoms, because each atom is cut of a particular chemical molecular environment.’3For Popelier, that attests to the ‘richness of chemistry’ – but it’s ...
Natural diamonds are unique, Magaña says, because each is formed in what amounts to a natural crucible that can never be recreated. That’s true of the overall time period when natural diamonds formed, as well as the conditions of each individual diamond during that time. But natural diamo...

One thing I remember from chemistry is that a crucible is essential for conducting volatile experiments – which we will see as multiple forces collide to create new fraud trends in 2021. Keep up with my thoughts on fraud and financial crimes as the New Year unfolds. Follow me on Twitter@Fr...
