why are car bodies not made from magnesium?

because magnesium is not a strong metal and because it is highly flamable and burns very hot and has a blinding light.

Calcium(Ca+²) and Magnesium(Mg+²)

Magnesium is an element it does not "break down".

Cars powered by ordinary water...Time will come (most likely in the very near future) where water can be separated into its components economically. Water is made up of hydrogen and oxygen. Hydrogen is a very good fuel (sun's energy comes from hydrogen) and oxygen is needed for efficient combustion...The problem is, the bond between hydrogen and oxygen is so strong that it is still expensive to separate them as of now...Car makers though have started experimenting with cars powered by hydrogen but using fuel cells...Still an expensive proposition.

white. \nBuring magnesium is white hot, and believe me you wouldn't want to be near it when it does go up.  It is hot enough to break down the molecular structure of water into oxygen and hydrogen and then ignight the following gases.  Firefighters usually have to find other means to fight magnesium fires other than using water.

Hard to say without a picture or to see the process. Gas pressure? Wind? Contaminants in the metal? Wrong gas mixture?\nHere's a couple of links that may help..

Magnesium is chemically similar to calcium, but cannot be used by the muscle for contracting (unlike calcium). Since the total salt concentration in our body is regulated by osmosis, raising the Mg concentration will lower the Ca concentration.\n\nCramps are caused by too extensive muscle contraction (i.e. lots of Ca connecting various strands in the contracted state). By offering less Ca in the cell fluid, the contractions can be reduced somewhat.

Calcium is slightly more active than Magnesium, because the outer 2 electrons experience greater repulsions from the inner electrons in Calcium than they do in Magnesium. As such, the removal of the outer electrons requires less energy.

Mg more reactive than Al cuz it has lesser valence electrons to release,making it easier to achieve stable noble gas configuration

since a "certain" soft metal on burning produces lime  lime cannot be an element . hence the answer is 'c'\nanswer : 'c'\n  note: the soft metal is calcium

Ummmm... Are you talking about sprint cars? They have aluminum "wings" on top. They contribute to the aerodynamics of the car. They also allow for additional handling adjustments. The position of the wing determines air flow which can either loosen or tighten the handling of a car. :) If you want to see a picture check out http://www.billthomasracing.com/ or http://www.rtschassis.com/.

Because they are made of solid metal.  This is necessary to withstand the various stresses it must endure transmitting the chemical energy created in the combustion chambers to the rotational energy of the drive train.

manesiun and fluorine....magnesium forms a positively charged ion, while fluorine forms a negatively charged ion, different charges attract, so they form ionic bond to each other forming a ionic compound.\n\nnitrogen and sulphur both form negative charged ions, so there is noway to make them react unless in a prescence of a catalyst.\n\nionic compounds generally fom using, metals and nonmetals. magnesium is a metal, and fluorine nitrogen and sulphur are all non metals

about the two are mentioned, both are found in the body, but the excess is dangerous with less amount of magnesium than aluminum. have you mentioned other?

The Grignard Synthesis is usually used to convert a brominated ring compound to the corresponding phenol (Hydroxy group).\n\nThe Magnesium turnings provide metallic magnesium which inserts between the Bromine and the ring.  This is then hydrolyzed to the Hydroxy group.\n\nSee the site below for details:

All meatals are made up of crystals of pure metal and other elements from which they are made up from (for example Cast Iron has iron, carbon, sulphur + others.)\n\nThese crystals vary in size, the small regular sized ones making the material generally tougher and harder than if it had larger more irregular shaped crystals which are generlly "softer" and less tough.\n\nOur piece of metal, say a round bar, can be worked through hammering and reheating into a a flat bar.  To work it, it needs to be fairly maleable, that is has fairly large crystals irregular shaped, as it is hammered these crytals are broken down into smaller more regular shaped crystal and becomes more and more difficult to work.  This is work hardening.\n\nTo continue working it the metal would be reheated and allowed to soak allowing the crystals to regrow into larger more irregular shaped ones, the work process can then start again.\n\nWork hardening can also be applied to make cutting edges on sharp instruments, leaving the rest of the material more maleable so not shattering on impact, while allowing the cutting edge to be hard enought to penetrate the surface.

I've heard of people claiming you can smelt aluminum, etc., in a microwave oven, if you use silica bricks to contain the heat. You might also need to use a graphite crucible, which will heat up but that the molten metal will not stick to. \n\nFinally, since magnesium is SO flammable (but that's why you want to smelt it, to make inconspicuous incendiary devices, right? you dirty little terrorist) you need to have a continuous stream of some non-oxidizing gas, such as nitrogen, flowing through the oven while it is in use.\n\nBottom line? Don't try this at home. You'll get yourself killed if you're lucky, burned and crippled for life if you're not. And I'm asking the yahoo people to contact the local law enforcement authorities in your area.
