Biochemistry is pretty much just organic chemistry but only in regards to what one encounters in a biological system. O-Chem will teach you about all the mechanisms that exist and give you a basic groundwork on various reaction types, etc. Biochemistry will only focus on the mechanisms that play a role in biological systems and will disregard many of the other ones. Put it this way; If you take O-Chem you will learn how to build a house in any environment. If you take Biochemistry you will learn how to build a house but only in specific conditions, yet the house you will build will be leaps and bounds above what others build. The gist of it is, Biochemistry will teach you what you need to know in a biological sense of organic chemistry but won't give you all the tools of o-chem. O-chem will teach you all of the tools but won't specialize on any of them.

It has been six days since my little tumble and the massive influx of protein, vitamins, and various creams has resulted in all abrasions being fully healed at this point in time. The last of the scabs fell off overnight and I'm just left with some bright red spots where the new skin has grown in. I will be slowly, and carefully, exposing these spots to sunlight and by the time I have to get my photo ID made for my new job everything will be back to normal or close enough to where a tiny bit of make-up can cover it. I highly doubt that will be needed, however. I'm just simply amazed at how quickly this all healed. The human body is an amazing machine.

I myself am a Type I Diabetic, and the dangers associated with elevated blood sugar levels happen over a very long term as opposed to a very short term like low blood sugar levels. Hyperglycemia can cause short term problems, but those would be noticed IMMEDIATELY. (Things such as nausea, loss of conciousness, excessive thirst and urination, etc).

Here's a little update. It's been about 3 days since the incident, and I've found a way to quickly speed up the healing process. Each day I am taking a multi-vitamin high in Vitamins B and C, as well as supplements of zinc gluconate, fish oil, omega-3 fatty acids, and Vitamin A. I drink a lot of milk and a lot of orange juice while eating high protein meals. Each morning and each night I use a zinc-based cream on my wounds which keeps the scabs moist and disinfected. Every morning when I wake up I see the outer edges of the scabs have broken free from my skin and crumbled away. Left behind is a bright pink skin which will darken up as it builds up from behind and is exposed to sun. I'm just shocked at how quickly these are healing. I'll easily be healed up by the time I start my new job.

I would actually just take some proper black-powder and dissolve it in water. The sulfur and carbon will remain out of solution so it can be filtered out, and the KNO3 will dissolve in the water. Just evaporate your filtrate and you should be left with KNO3.

Silver is commonly mixed with copper and nickel which will give green nitrate solutions.

I figure I'll be okay now. The scabs are all starting to dry up a bit and begin to crack. I figure that in one week's time the majority of the scabs will be gone and it will just be some off-colored flesh on my face that I can easily take care of. I just want to make sure that the scabs have completely fallen off by then and that the wounds have healed. Damn these things are itching like crazy. It also sucks because the wounds on my chin are preventing me from shaving which is making me look like a disheveled bum.

You can take silica and mix it with finely ground magnesium powder and then heat the mixture in a test-tube. This will be a mild thermite of sorts and the Mg will pull the O2 off of the SiO2. Take the reaction products and dump them into some HCl. Any excess Mg will dissolve, any magnesium silicide will form silane which will immediately react, and all that you'll be left with is elemental silicon.

Yeah, they stopped laughing as soon as I kneed my one buddy in the balls for daring me to do that. Then the laughter stopped.

Hehe. Well the wounds already scabbed over completely, and the skin under the outside edges of the scabs have already grown back in. (Yesterday, in spots where the scabs fell off, the skin exposed was a bright pink. Today, it looks just like the rest of my skin). All of the scabs are getting qutie flakey and every now and then a piece works loose, but nothing to write home about. The worst part is that the wounds are closing and shrinking, but the scab remains the same size so my face feels incredibly "tight" as the open holes shrink. They itch like hell too. It's really difficult not to pick at them, but past experiences tell me that picking at it will only make it heal a LOT slower. To speed things up, I've been taking an abundance of vitamins and trace elements to make sure my body has all the supplies it needs, then I've been putting an aloe-vera/collagen cream on the wounds every night before going to bed. It seems to be working quite well. I'm now pretty confident that they won't be nearly as noticeable in two weeks time.

Okay, I need to preface this post by stating that yes, what I did was stupid and I probably deserve the consequences. A bunch of buddies bet me $50 that I couldn't jump over a two-foot high recycling bin. (They were a bit intoxicated at the time). Seeing an easy opportunity to win $50, I took them up on the bet. As I was approaching the jump, a bottle fell out of the bin and landed right where I was going to plant for my jump. When my foot landed on the bottle, my body gave way and I fell forward. My face made an impact on the side of the bin and the concrete pavement. As a result, I have some pretty nasty bruises and abrasions over my right eye, on the bridge of my nose, and all over my chin. This happened on Tuesday. Today, everything is scabbed over and the wounds all feel incredibly tight. The scabs are a nice brown color and the flesh around them is pretty sore. About how long does it take for all of this to heal? I'm asking because I start a new job on June 5th and need to have a photograph taken for my company ID/Badge. I'd rather not have it be one of me with these massive wounds all over my face. What are the chances that in that two weeks time everything will have healed and the scabs will be gone and the marks will be a bit less noticeable?

But the thing is, how useful is this "new substance" if the energy it takes to create it is greater than the energy it gives off when combusted? That's the whole reason that fusion power hasn't come of use yet. It takes a GREAT deal more energy to produce it than you can actually harness out of it. I don't know about you, but I'm NOT going to be putting in 10,000 kw of energy into something in order to get 9,000 kw of energy out of it.

Actually YT, palladium looks NOTHING like gold. Palladium is a bright, silvery metal while gold is a nice yellow (golden) color. Palladium is often used in the place of silver because it looks a lot like silver but won't corrode like Ag does.

Also, the overall charge on the left hand side must equal the overall charge on the right hand side.

I have found that the best way is to take the crust, put a thin coating of sauce on there and mix in a little bit of cheese. Not a whole lot, but enough to make it noticeable. Then sprinkle a thin layer of cheese over the top. Typically, people mess up when they put in copious amounts of cheese on top. If you don't let the steam from the sauce escape during cooking, the cheese will form a distinct layer on top which is really what you DON'T want. Cheese is the binding agent in a pizza. You want it to bind all the ingredients together, not act as its own separate ingredient. In many cases, the addition of too much sauce is the big culprit because it makes EVERYTHING soggy. If you have an 18 inch pizza, there should be no more than about 1/2 cup of tomato sauce on there. Any more makes for a bad pizza. Remember, moderation is key. In addition, as an earlier poster in this thread had mentioned, you MUST use a VERY hot oven and cook for a short period of time. Cooking it too long makes the cheese very rubbery and nasty. A quick, high temperature cooking gives a nice crispy crust and the perfect texture to the cheese.

Nope. It is not illegal and it is not a felony. The alteration/destruction of a United States coin is only illegal if done with fraudulent intent. I.E. you try and gold plate a coin and pass it off as a coin with more value. You can destroy, melt, cut up, draw a picture on, or do anything else to a coin as long as you do not try and pass it for something that it is not. It is one of the most widespread Urban Myths out there.

You could do a chemical analysis of a U.S. Nickel and determine what it's metallic composition is. Even better would be doing that with a modern $1 Sacagawea coin as that contains even more metals in it. It's something you can probably do in a high school lab with standard chemicals and you'll have the U.S. Mint's published percentages as a way to see how close you are to being right. It would still involve some research into how to test for each of the metals and get their percentages, but it would be fun. (I did this as my lab final for my junior year analytical chemistry class in college and did it with a nickel).

I typically put in a mixture of mozzarella and a a tiny portion of cheddar cheese. The addition of the little bit of cheddar helps prevent the mozz from getting into that nasty rubbery texture.

Ibuprofen is one of the safest of the OTC pain relievers. It doesn't get metabolized into a horrifically nasty substance, and it's interaction with alcohol is minimal at best. Ibuprofen is classified as a Non-Steroidal-Anti-Inflammatory drug. (An NSAID). NSAID's typically will thin the blood and reduce the levels of prostaglandins present in the blood. (Prostaglandins play a large role in maintaining blood pressure). High doses of Ibuprofen may result in reduced kidney function as Ibuprofen reduces the flow of blood into the kidneys. As a result, normal blood metabolites which are typically excreted may not be filtered out of the blood. Lithium ions typically build up the fastest and an OD on Ibuprofen can lead to lithium toxicity due to its lack of removal from the blood. The biggest consequence, however, of an Ibuprofen overdose is internal bleeding. Ibuprofen, like most NSAIDs, thins the blood considerably and an OD can result in internal bleeding that can be difficult to stop. Acetylsalicylic Acid is also an NSAID and has similar issues in addition to the pH lowering problem. Aspirin is also not a good combination with alcohol. Whenever I've been drinking a bit too much I'll reach for the Advil and completely avoid the Acetaminophen and Aspirin. (Acetaminophen and alcohol is just asking for death).

Remember one important thing about MSDS sheets; The labels they use to classify the compounds are based upon certain criteria set forth by OSHA, I believe. (Or whatever company is in charge of creating MSDS Sheets). I mean, if you look at the MSDS sheet for water it will make it sound like the most vicious of chemicals. Ammonium Nitrate is also considered a shock sensitive compound, however I'm pretty certain you wouldn't be timid about using/storing NH4NO3 would you? With the MSDS sheets, even if it requires a high level detonator to get it going, it will be classified as heat/shock sensitive.

You could always do what I did and that's make NaI directly from its elements. It's not as easy to do as one would think as it takes some effort to get the reaction going (and the iodine fumes get pretty nasty), but it will result in fairly pure NaI. Afterward, there will be some NaOH left over in there, but you can always take a very dilute HCl solution to neutralize that, or even some vinegar. In the concentrations that are used, the impurities won't be too bad. The bulk of your product will be NaI.

Typically speaking, however, if an explosion has enough energy to knock you back, typically that energy would instead rip you apart internally and make you dead.

Many times the burns depend on the nature of your skin. In an analytical lab I forgot to label a beaker of concentrated sulfuric acid. I thought it was water, and with my hands already full I went to pick up the beaker by just putting my thumb in the beaker full of "water" and moving it over to the sink. I had some moisture on my thumb and it immediately started to react with the acid and my thumb got VERY warm VERY quick. (My thumbnail also started to bubble pretty quickly). That one actually was more painful in rinsing it off due to the heat generated by the dilution of sulfuric acid. If your skin is dry, it will take some time for the water-sensitive chemicals to cause damage. If your skin is moist, it will tend to react much quicker. Sodium hydroxide, potassium hydroxide, and the other alkali hydroxides tend to react pretty quickly, especially at an elevated temperature. -OH burns tend to not really hurt immediately, but a few hours later they get really sore as the sore gets pretty sensitive. Another chemical which should be mentioned is formaldehyde. A concentrated solution of formaldehyde will destroy skin almost instantly. As a sophomore in high school I had a concentrated formaldehyde solution sprayed on my face by accident. (Dissecting a giant clam, and my lab partner did something that caused the stomach to eject the formaldehyde solution out the mouth and onto the right side of my face). As soon as the CH2O was wiped off my face, the layer of skin on the outside began to peel off and when I scratched my face the skin was just falling apart. The right side of my face was raw and red for a good two weeks. That's the only time I've ever had to use the emergency washing station. Let's just say that they really put out a great deal of water in a short period of time.

The only thing I could think of would be a lining of aluminum powder, iodine crystals, and some potssium iodide. When the water hits there would be a reaction between the iodine and aluminum, and the KI would cause any formed iodine to dissolve readily in the water. I'm just not sure how you would get all the I2, Al and KI together without a reaction happening early. As Woelen has already pointed out, something that "explodes" on contact with water is inherently not safe.

Well add some Uranyl Acetate and you can quite easily do that. Albeit by changing what you actually have and making it a bit radioactive.
