Not so important differences:
Heavy metal ash (but also in general ash): ash resulting from the calcination of a material; practically is a mixture of oxides.
Sulphated ash: the sample is initially treated with sulphuric acid and the residues are calcined.
Sulphated ash is the amount of inorganic residue left when a sample is ignited after treatment with sulfuric acid. On the other hand, residue on ignition is the amount of material left behind when a sample is ignited without any prior treatment. Sulphated ash is typically used for organic materials, while residue on ignition is often used for inorganic materials.
Yes, lead is considered a heavy metal. It is a dense, soft, and malleable metal that is classified as a heavy metal due to its high atomic weight and toxicity.
Tungsten is a hard, dark, heavy metal that is non-magnetic.
Sulfuric acid is used in the sulphated ash test to convert the inorganic components present in the sample to their sulfates. This step helps in ensuring complete combustion of organic material and facilitates the determination of the ash content accurately. The use of sulfuric acid also helps in removing any carbon residues that may be present in the sample.
No, trichloroethylene is not a heavy metal. It is a volatile organic compound commonly used as a solvent in various industrial processes. Heavy metals are elements like lead, mercury, and cadmium that have high atomic weights.

Heavy metal has no relation to the Antichrist. Although there are a few Satanists in metal, most use the symbolism for shock purposes.
None. It's how the instruments are played!
Helium is a gas that is lighter than air. Iron is a solid metal and is heavy.

Heavy Metal was originally coming from Rock. Because Rock isn't that hard like Heavy Metal and Heavy Metal was invented, it shows the difference between both music genres. Heavy Metal must have hard beats as same as country music needs accustic guitars and heartbroken lyrics. Same as techno needs infinite amounts of the same beats with few breaks, but the rythm is the same all the time in a loop.
There are no solid links to Satanism and heavy metal, heavy metal artists use Satanism insignias to get publicly.
Hardcore band is somewhere along the lines of screamo with heavy instuments, Metal is just the main genre with craploads of sub genres such as Power Metal, Heavy Metal, Thrash Metal, Death Metal, Symphonic Metal, Black Metal and many more. Each sub genre has its own distinct sound but at the same time maintain the title "Metal".
Alter Metal is a cross genre between Grunge/ Alternative and Heavy Metal. Anter Metal and Alternative Metal are different in many ways, such as Alter Metal bands have a grungy look to them. And Alter Metal leans more towards Grunge/ Alternative, and Alternative Metal is more Heavy Metal.
A heavy barrel has less metal removed when it is being contoured from a blank. This makes a heavy barrel have thicker walls, which allows it to absorb more heat and distort less. Heavy barrels are usually used by target shooters.
