"Red cat, Anny Ox" (Reduction at the cathode, oxidation at the anode. )and "LEO says GER" (Lose electron oxidation/ gain electron reduction). Knowing these two phrases (?) you will know how electrons flow and can tell which is positive and negative with ease.

Hi Westlund, When you look at a problem it may help to write down the symbols for the things you are given and the things that you are looking for. Then, try and find an equation relating the known and unknowns. In this case you are given two energies one at ground state (E0) and another at...

I am not too sure if I follow you based on the information you provided. But, (and somebody please correct me if I am wrong) you need to find out the amount moles of each substance present at the end of the reaction. From that you would then need to determine the mole fraction of each...

Hi, I am not deeply familiar with electromagnetic and optical properties of materials (But, I am taking a course currently). Anyway, I just did a little googling and found this article (doi:10.1016/S0040-6090(02)00202-X) on beta Ga2O3. I think what you may want to do in order to...

From my understanding (or lack thereof), you do not need any specific modifications to a protein in order to study a specific area in dynamic raman spec. studies (provided that the area(s) of interest are identifiable and show strong enough absorbance/signal). However, more often than not...

Hi Friend, When you are looking for help on these boards please be patient and wait for someone to assist you. As for your question on how to calculate the atomic mass, in order to find the atomic mass of an element you must take the weighted average of its isotopes (based on percent...

Hi Madah12, You may want to look up Charles's Law and Boyle's Law. These may help you out. As far as the weight of trust you place in Wikipedia... that is another issue. I recommend using a stronger and more credible source for scientific information.

You may want to check the CRC Handbook of Chemistry and Physics, or MERCK Index, or NIST, or (if you have access) Knovel. This website might give you an idea of where to look (might help to branch off from some of its links): http://tigger.uic.edu/~mansoori/Thermodynamic.Data.and.Property_html...

Hi, The last post pretty much summed it up- it depends on what the nature of the product you are attempting to preserve. If you would like more information on preserving foods you should take a look at "cook books" specifically targeted for preserving for advice. As for the science...

It seems as though you may have taken enough classes to do well on the GRE Chemistry subject test. I took the test last November and it in no way went into any amount of detail. I found completing the GRE sample chemistry test to be helpful, as it helped me to identify areas where I lacked...
