What else can I help you with?
Why is aluminium powder flammable?
Aluminium reacts violently with oxygen (any aluminum surface will very rapidly be covered with AlO2 [aluminum oxide]. If you have a powder the surface area is large and the reaction when heated will be quick enough to generate flames. Steel wool will also burn!
Which has a larger surface area powder or lumps?
Powder typically has a larger surface area compared to lumps because the fine particles in powder allow for more surface area to be exposed. This increased surface area can be advantageous for processes like absorption or dissolution.
How chlorine effect to aluminum can?
Chlorine can react with aluminum to form aluminum chloride, a white powder. This reaction can corrode the aluminum surface and weaken its structure over time. It is important to avoid exposing aluminum to chlorine or chlorine-containing compounds to prevent damage.
Will aluminum powder float or sink in water?
It will sink, but sometimes a little bit will get stuck on the surface for a little while. It will sink too if you give it a little bit of time.
Why do powder chemicals dissolve faster than solid chemicals?
Powder has a larger surface area than ribbon. Now do the rest of your homework yourself!
What do white powder spots on aluminum hull indicate?
oxidation of the aluminum surface
What is the white powder that forms on the surface of aluminum when it corrodes?
Aluminum oxide - Al2O3.

What has the larger surface area a lump of chalk or chalk powder?
Chalk powder has a larger surface area compared to a lump of chalk. This is because the process of grinding chalk into powder increases the total surface area exposed to the surrounding environment. As a result, the smaller particles of chalk powder provide more surface area for reactions, interactions, or absorption than a single lump of chalk.
How do you separate aluminum powder and salt?

Why does a powdered solid have a larger surface area than a solid lump?
Each speck of the powder has a smaller surface area than the lump of solid, however the total surface area of the powder specks will be greater than that of the solid lump
Why aluminum can't behave in the same manner as powdered aluminum?
If you're talking about burning, then no. Powdered aluminum has an extremely high surface area, and oxidizes very quickly. An aluminum can does not nearly the same amount of surface area, and oxidizes much more slowly, so it won't burn readily.
What is the difference between extruded aluminum and powder coated aluminum and anodized aluminum?
Extruded aluminum is aluminum that is melted down and extruded, pushed through a certain 2d shaped hole. This can result in square tube, rectangular tube, an L shaped extrude, and an infinite array of other shapes. Powder coated aluminum is aluminum that could be extruded aluminum, that is cleaned, coated with a colored plastic powder, and then baked so that the plastic powder melts and forms a smooth, nice and even coat of colored plastic over the part. This is basically painting the part. Anodized aluminum is aluminum, again this could be extruded aluminum, but it couldn't be powder coated aluminum, that is put in a chemical solution, possibly sulfuric acid, and then a current is run through the aluminum. This causes a reaction to occur where a layer of aluminum oxide gathers on the surface of the part. The processes is then stop and the part can be colored if desired. Anodozing aluminum gives the part better corrosive resistance and makes the surface tougher and harder than it would have been if it had not been anodized. It does add thickness to the part which can be a downside, but it also is lighter than a powder coat if a paint job is desired.

What metal is dusted on a glass surface to make an Etch-a-sketch?
It is aluminum powder. The powder is mixed with polystyrene beads, which help distribute the powder. It's possible that the beads also create a little electrostatic charge, which makes the powder stick to the glass better.
