(a) Why do many organic compounds have low melting and boiling points? (b) Some organic compounds, like table sugar, do not have a boiling point. Suggest a reason why. Explain why the the structure of a molecule/compound is important....
Explain why it is difficult for scientists to determine the effects of any particular chemical on human health, such as the phthalates that are used in plastics and many other products. In other words, what makes risk assessment so complicated? Explain the difference bet...

Explain why graphite has a lower melting point than diamond even though both are carbon compounds. (a) Why do many organic compounds have low melting and boiling points? (b) Some organic compounds, like table sugar, do not have a boiling point. Suggest a reason why. How ...
Consider the equation food + water + x = life, what additional factor (x) would you add? explain why you consider this factor is essential to lifeLife:While there are many definitions of life, most include the idea tha...
Why does a hydrate exist only as a solid? What characteristic of a hydrate is responsible for this phenomenon? What is the difference between a hydrated compound and an anhydrous one? Explain why water is such a good solvent for so many different s...
Mass Spectrometry Mass spectrometry is a very powerful analytical technique that is very useful for structural elucidation. In general, a molecule is broken up into fragments and some fragments will be charged. Mass spectrometer can analysis the fragments and provide the relative numbers of the differ...
auris strains suggests that it has been on Earth for many years given the amount of time needed to produce its levels of genetic diversity. Why then have three clades of C. auris begun emerging now, causing transmissible and invasive infections on a large scale only in the past decade in ...
