Circulon - reactive or nonreactive?
Manufacturers found that aluminum can be anodized to make it stronger, slicker, more durable, and non-reactive with foods. This applies to many types of cookware, including Circulon and Calphalon.Calphalon, a maker of anodized aluminum cookware explains it this way:"Hard-anodization is an electro-chemical process that hardens aluminum. (Hard-Anodized aluminum is 30% harder than stainless steel.) During hard-anodization, aluminum is submerged in an acid bath, then subjected to electrical charges. The result is a chemical reaction wherein the surface of the aluminum combines with oxygen to become aluminum oxide. This reaction is also known as oxidation, a process which occurs spontaneously in nature. Hard-anodization is actually controlled, accelerated oxidation.
Are most metal elements brittle and don't conduct electricity?
No, it would be a nonmetal. Metals are usually malleable and do conduct electricity well.
What does appearance and properties mean?
Appearance means what it looks like, Property's means what can it do for example is it hard or soft, does it conduct electricity, is it malleable. etc.
Why is aluminum hard to mine?
It's hard because of the chemicals that are inside of it. Though aluminum foil is not so hard it's still made out of aluminum.
What are the properties of lead sulfide?
Sulfides such as pyrite (feS2) are compounds of sulfur and one ore more elements.

What is the purpose of hard anodized cookware?
Hard anodized cookware is produced for the purpose of stopping food from sticking while cooking. Anodizing is a chemical process that hardens the surface of the cookware to a point where the pan is no longer porous.
What matrieal that conduct electricity?
Usually Metallic substances conduct electricity and heat- They are good conductors of heat because solid particles are close to each other and vibrate frequently. The properties of metals are shiny usually hard and perpetual- some have special attributes such as aluminum which is light and fairly strong.
Is clay a conductor?
No it does not conduct electricity, and when hard it acts as an insulator..
What characteristic do solid ionic compounds share?
In general, they are hard, brittle crystals that have high melting points. When they are dissolved, they can conduct electricity.
Are most metal elements brittle and don't conduct electricity?
No, it would be a nonmetal. Metals are usually malleable and do conduct electricity well.
Is anodized aluminum still aluminum?
Yes, but it has a hard transparent (sometimes colored) layer of aluminium oxide grown on it by putting it in an electrolytic cell (as the anode) and passing current through the cell. This layer protects the aluminum metal under it from damage. Note: if the anodization is red in color the aluminum oxide layer is actually synthetic ruby.
What is a nonreactive baking sheet?
Stainless steel, tin lined copper, non-anodized aluminum, clay, enamel, glass, or plastic are all non-reactive. A reactive pan is one made from a material that reacts chemically with other foods, such as aluminum, copper and cast iron. The materials react with acidic foods, imparting a metallic taste and will sometimes discolor light colored soups and sauces a light green or gray! Anodized aluminum has a hard, corrosion-resistant surface that helps prevent discoloration, so it is ok to use. Also, avoid stirring light-colored sauces and soups with an non-anodized aluminum metal spoon or whisk.
How can anodised metal be cleaned?
Only aluminum is anodized. The anodizing process creates a layer of aluminum compound that is very hard, and is often colored. Since it is a thin layer, only detergents and very fine powdered cleansers like Bon Ami should be used.
Why should an electrician wear a plastic hard hat?
Electricians should wear plastic hard hats because they will not conduct electricity.
What are the properties of a ionic compound?
They are hard and brittle, conduct electricity in water, and have high melting and boiling points. (:
Does zinc conduct electricity when solid?
yes it does, zinc is an ionic structure so it will be hard to xbreak the bonds so it would have a high melting point but it will conduct electricity because it will goe through the bonds but keep them intacked.
