Is powder a solid or liquid?

Answer 1

A compound is a substance made of two or more elements chemically combined in a specific ratio. For example water (H2O) . This tell you that the ratio of hydrogen to oxygen is 2 to 1.

A mixture is two or more substances that are mixed together but not chemically combined. For example, soil is a mixture of sand, clay, water, and other particles.

Since powder is a mass of fine dry particles we would have to check to see if the particles are the same (compound) or different (mixture).

Answer 2

Powder is a solid because it has no viscosity (the ability of a liquid to flow). Most liquids that we'll encounter have these different viscosities which range from low being something such as water which flows freely, to high being glass, yes glass is in fact a liquid as well. To better tell the difference between solids and liquids ask yourself, does it fall or pour.

and also to be a liquid it needs to beable to have something flout on i and rise to the top when buried

Answer 3

Perhaps "white powder" is another name for talcum powder or something? (In which case: mostly powdered talc; probably some fragrance and anti-caking agents, so a mixture.) It's impossible to say if something is a compound or mixture simply by looking at it and noting that it's a powder and that it's white.

Answer 4

Any non- waxy solid can be subdivided and look powdery. Covalent compounds are often liquids or waxy solids but there covalent solids, these tend to be network covalent or long chain polymers.

Answer 5

yes

Answer 6

yes

Answer 7

No
