I hate to be too much of a genre know it all, but this has been bugging me for a long time. I love all sorts of progressive metal bands, but I don’t know what differentiates them from the other genres of metal. Bands like Symphony X, Suspyre, and Pathosray are examples of progressive metal bands that I like.

Progressive metal (sometimes shortened to prog metal) is a fusion genre: a mixture of progressive rock and heavy metal. Progressive metal blends the powerful, guitar-driven sound of metal with the complex compositional structures, odd time signatures, and intricate instrumental playing of progressive rock. Some progressive metal bands are also influenced by jazz fusion and classical music. Like progressive rock songs, progressive metal songs are usually much longer than standard metal songs, and they are often thematically linked in concept albums. As a result, progressive metal is rarely heard on mainstream radio and video programs.

Why does aluminum foil burn in the microwave but not in the oven?

Aluminum foil doesn’t actually burn in the microwave. What you are seeing is called the "electro-magnetic effect." Microwaves travel as particles called photons, and when those photons hit your aluminum, they collide with the aluminum atoms and create extra electrons. Now, in larger pieces of metal, like a fork or a thermos, these electrons are distributed throughout the bulk of the object, but on thin pieces of conductive metals, like aluminum foil or gold plating, these electrons quickly build up a significant electric charge. What happens next is the same thing that happens when you drag your sock feet across the carpet in the winter and shock someone with the static charge. Sparks begin jumping from one part of the foil to another, or from the foil to the microwave itself. These sparks can cause a fire and ruin your microwave oven, to say nothing of your poor baked potato. Conventional ovens do not use microwaves, but rather just heat up the foil. Aluminum won’t catch fire no matter how hot you get it, although it will eventually melt. But it is unlikely that your conventional oven will ever become that hot.

I’m allergic to nickel and I have nickel free earrings but I think they are still irritating my ears, any suggestions?

try gold or silver earing

Arsenic has a +3 charge, but trichloride would already have 3. So would it be AsCl3 or As(Cl3)3?

The formula is AsCl3. Arsenic has a +3 charge, chloride has a -1 charge.
When you write out the formula it becomes AsCl3–it is trichloride because of the +3 charge on As ion.

I need 3 different metals to use. If anybody knows any good metals that you can buy in a store, please list some.

Thanks!

Get some tacks from a hardware, brass, steel, aluminum, and stainless steel. You could also go to a machine shop someplace and get them to file some metal for you into envelopes to use. Since the filings are so much smaller the effects will be faster than the tacks. Use a measured amount of each(equal teaspoon or grams per container).
Put each of them in a small separate GLASS container with some measured amount of soda. Baby food jars come to mind since they are small. After a few days, the steel one will begin to rust/deteriorate. You might want to use different kinds of sodas to see if they give different effects also. 4 metals, 4 sodas, 16 glasses. Be sure to label each glass with the contents of each so that if a tack (filings) becomes totally dissolved you will know which is which.

My husband works at a printing plant where they use a web press to print advertising inserts. Are there heavy metals in the inks, solvents and cleaners used in this industry, does anyone know? If not, how could we find out?
We are wondering because he often gets the chemicals/ink all over him and breathes them in all night long.

Material Safety Data sheets should be available for all chemicals used on site. They are often available on line from the manufacturers web sites. Modern inks used in 1st world countries probably wont contain heavy metals. They used to be used as colored pigments e.g. yellows, orange red were often made with lead and cadmium pigments. They are harmless however unless often eaten in moderate quantities which is highly unlikely. Modern colors use organic dyes & pigments.
Solvents & cleaners do not contain heavy metals.

I understand the initial process being thermal decomposition changing the compound into copper oxide. I would relish in the knowledge of how to then change this into copper. Please help. Thank you.

not sure if this is helpful..im a little rusty

I have some Nickel Cadmium Batteries, each one has 2 cells . They are aproximately 15" x 6" x 8", I guess they weigh about 10 kg each. It says the brand name is NIFE. I’m on a 12v solar power system for my home and need to know how many of these Nickel Cadmium batteries I need to replace my dying leadacid battery bank. At the moment a multimeter puts them between 2.4v and 2.8v per cell, but I don’t know their present state of charge

I hope you mean 2.4 volts per battery, which is 2 cells. This puts the cell voltage at 1.2 volts, about right for Ni-Cd.

2,4 volts per cell doesn’t make sense.
