E is simply hexane...no polarity at all...nothing to speak of has extra electron density. A is a benzene ring, and if you play with the resonance you will see that sometimes the electrons can be in many different places which will make it polar at those times. :) nate Solution E is simply hexane...no polarity at all...nothing to speak of has extra electron density.

I would say very many elements exista as monoatomic molecules.All the metals,for example.Don\'t get confused by the fact that if metals have a crystaline structure,then the molecules would be composed by more than one atoms... An Element Is A Single Atom. No, an element is any material that is composed of only a single kind of atom (ie: all its atoms are identical) While A Molecule Is A Group Of Atoms That Are Bond Together To Form Another Compounds... A molecule is a group of atoms that are bonded together, but they do not form a compound. A compound is is something whose molecules contain more than one kind of atom. Some Elements Exist As A Diatomic Atom. Some elements are a collection of diatomic molecules. You can not have a diatomic atom - that\'s self-contradictory. Example Of These Are Hydrogen And The Halogens Family( Chlorine. Fluorine Etc.) In Case Of Hydrogen. Hydrogen Is A Diatomic Atom. If The Hydrogen Bonded To Other Elements This Is An Example Of Molecule... Hydrogen is made up of diatomic molecules. If hydrogen bonds with atoms of another element you get a compound. In Short Element Is A Single Atom While Molecule Composed Of 2 Or More Atoms That Are Bonded Together. You can not compare an element and a molecule. You can compare an element and a compound. An element is made of only a single kind of atom - whether as a crystal (Fe), or isolated atoms (He) or as molecules (H2), does not matter. A compound is made up of molecules (or crystals) with more than one kind of atom (NH3, H2O, NaCl) Solution I would say very many elements exista as monoatomic molecules.All the metals,for example.Don\'t get confused by the fact that if metals have a crystaline structure,then the molecules would be composed by more than one atoms...

Ferroxyl contains the chemical compound Potassium ferricyanide which reacts with the ferrous ions to produce the color \"Prussian blue\". Iron is being oxidized at the anode and creating Ferrous (Fe+2) ions. Therefore, with the introduction of Ferroxyl, the anode will turn blue as the Ferroxyl reacts with the Ferrous ions. It is also worth noting that this is a acidic solution and the blue pigment is insoluble in water. This is useful in detecting metal oxidation that leads to rust. Same thing basically for the OH.

There are two different types of mechanisms. There are elimination and substitution reactions. The elimination reaction is when there is a proton transfer and loss of leaving group taking place. The substitution reaction is when there is a loss of leaving group and nucleophlic attack. From what we see in this reaction, we see that there is a nucleophilic attack with the MeI and OH. So this is a substitution reaction. Now to determine whether it is SN1 or SN2, we would have to look at the reaction. There is a tertary compound, which favors SN1 reactions better than SN2. The final answer would be SN1. I hope this makes sense. Let me know if anything is unclear. Solution There are two different types of mechanisms. There are elimination and substitution reactions.

When one drives from sea level to trailhead in high Sierras, altitude increases. At higher altitudes, atmospheric pressure drops and so does the oxygen content of the air. We run out of enough oxygen in blood for our brain and body that leads to dizziness and heavy breathing. This is detrimental as it can even stop our brain due to lack of oxygen. These symptoms are collectively called Altitude sickness which reduces, as one spends some time in such region as our body gets acclimatized to such environment.

The important thing here is to understand the Standard Electrode Potential for each of our metals involved. Whichever of the metals has a larger negative number is the one that will be our anode, the other will be our cathode. Therefore, for this reaction, we know that Aluminum is going to be our anode. With this reasoning, we know that where the anode is, so will oxidation occur. If we think about it, where oxidation is occurring, the metal (in this case Aluminum) is giving up electrons and feeding it to the other side. Since we know the salt bridge is there to balance out the lost electrons from the oxidation side, we know that the NO3- are going to flow to the left hand side to make up for the electrons that are going from the left hand side to the right hand side. Your salt bridge sends anions to the left hand side! Hope this helps! Solution The important thing here is to understand the Standard Electrode Potential for each of our metals involved.

Since HEPES is a zwitterionic organic chemical buffering agent. At pH<7.0 it exists as cation (a positive ion , as negative charge is compensated by H+ present in the solution) to bring its pH to 7.45 (basic region) we must add NaOH. pH will increase when [H+] decreases. To decrease [H+] we must add NaOH ( a base). Solution Since HEPES is a zwitterionic organic chemical buffering agent.
