What is thermite composed of?
399458
"A thermite reaction (a type of aluminothermic reaction) is one in which aluminium metal is oxidized by the oxide of another metal, most commonly iron oxide. The name thermite is also used to refer to a mixture of two such chemicals. The products are aluminium oxide, free elemental iron, and a great deal of heat. The reactants are commonly powdered and mixed with a binder to keep the material solid and prevent separation."\n\n"Uses:Thermite reactions have many uses. It was originally used for repair welding in-place such things as locomotive axle-frames where the repair can take place without removing the part from its installed location. Thermite grenades are used in war to destroy sensitive equipment or documents when at imminent risk of capture by the enemy. Thermite grenades and bombs have been used in combat as incendiary devices, able to burn through heavy armor or other fireproof barriers. Thermite can also be used for quickly cutting or welding metal such as rail tracks, without requiring complex or heavy equipment. It also enables infantry to destroy enemy artillery without the use of loud explosive charges and therefore operate with stealth. The mixture has been sold for many years under the trademark name Thermit for use in railroad welding."

francium. mercury is technicaly not a metal, it just has a low melting point, low metling points do not make it unstable. if that were the case, then oxygen would be VERY unstable ITS ALREADY TURNED INTO VAPOR!!!

Mostly hydrogen. There is a little bit of helium and heavier elements in there as well.

a) 3SiO2 +2 Al --->3 Si + 2Al2O3\n\nb)AgNO3 +HCl---> AgCl +HNO3\n\nc) Mg + CuSO4 ---> MgSO4 + Cu\n\nd) Pb(NO3)4 +4 NaI --->4 NaNO3 + PbI4 (s)

For the most part, fire is a mixture of hot gases. Flames are the result of a chemical reaction, primarily between oxygen in air and a fuel, such as wood or propane. In addition to other products, the reaction produces carbon dioxide, steam, light, and heat. If the flame is hot enough, the gases are ionized and become yet another state of matter: plasma.

Definitley the element, Mercury. With a melting point of -37.89 °F (-38.83 °C)\n\nhttp://en.wikipedia.org/wiki/Mercury_%28element%29

Ah ha.  Thermite.  Magnesium ribbon would be the usual method to start this reaction.\n\nBe careful with this reaction...

My thought is air as well. Air is composed of around 2/3s part of Nitrogen. Oxygen is a much smaller amount

Ca3PO4 and CuOH\n\n^^those are the answers

I remember this question since it was on the test once:\n\nList the following kinds of matter by how well they conduct heat (from the best to the worst): Wood; air; metal; water.\n\nMy answer was the correct one and it was: Metal; water; wood; air.

A mixture of two metals is called an "alloy."\n\nThere is *no* chemical reaction (the gold atoms are not reacting with the silver atoms).  It's just a melted mixture.\n\nWhite gold is an alloy of gold with other white metals, like silver, nickel, or palladium (source below).

Heavy Metal! Just joking. http://www.scienceproject.com/projects/intro/elementary/EX057.asp Go here, they have a lot of information.\n\nhttp://www.science.ca/askascientist/viewquestion.php?qID=1216 And this one. It is clear that aluminum conducts the best heat.

You are talking about specific heat. According to the chart at the link below, it's a tie between Radon and Radium. They have the lowest specific heat.\n\nSpecific heat is defined to be the amount of energy required to raise the temperature of one kilogram of the substance by one kelvin. You are asking about the elements with the lowest specific heat. Gold and lead also have very low specific heats.

mercury\n\nmercury is a liquid metal\nand its composed of potassium, sodium, oxygen, argon, helium, nitrogen, Carbon dioxide, water, and hydrogen

Alkaline: the oxides, when mixed with water, form alkaline solutions.\n\nEarth: Calcium and Magnesium are major constituents for most kinds of rock and soil.
