What does IUPAC stand for in chemistry? What does heterogeneous mean in chemistry? What does the chemical formula of a molecule determine? If the charge on the atom is 0, what does this mean? Define efflorescence in chemistry What does gauche mean in organic chemistry?
It seems that when Lehn called supramolecular chemistry a ‘chemistry beyond the molecule’ he was alluding to a very hazy frontier. Likewise, US chemist George Whitesides’ suggestion that chemistry should move ‘away from the molecule’ (in a paper provocatively titled ‘Is the focus on “mole...

at least one type of atom and at least one type of molecule. Mixtures can be formed from the intermingling of their constituents in any ratios or proportions (unlike compounds, which are formed from specific ratios of amounts of other elements). Mixtures can be separated into their constituents...

Chemistry class (Photo Credit : Elegant Solution/Shutterstock) When you see a molecular diagram or read a molecular formula, it may not immediately be apparent whether you are seeing a molecule or a compound. In fact, you may not even know if there is a difference between these two designati...
Re: What does a radical mean here? « Reply #1 on: August 17, 2014, 05:20:41 PM » A radical in modern usage is an atom, molecule, or other species with a lone (unpaired) electron. The language that the book uses is admittedly rather confusing. Example: case of sodium chloride...
Genetic make up comes from mutations within DNA. Deoxyribonucleic acid. Each cell contains 9 feet of DNA. In an average mean you eat approximately 55,000,000 cells; this is equal to about 93,205 miles of DNA. DNA is formed by a specific type of molecule called nucleotides. Each nucleotide...
Another thing I don't get is why single replacement reactois dont work in water. I mean I know of the thermite reactoion. but i guess that wouldnt happen in water.. SO what rol edoes it play? The most important reason for this is that in many situations water (and certainly water ...
