What is a compound and why is it not a mixture?

Why alloy is mixture and not a compound?

  • I found that alloys is a type of homogenous mixture. What exactly is homogenous mixture? (I've checked wiki and found that the explanation is complicated, please explain in simpler form, thanks!)

  • Answer:

    Alloys are mixtures because the elements that make it up are physically together, not chemically joined together as in a compound. To be plain and simple, a homogenous mixture is a bunch of molecules so close together (but not chemically joined) , that you can't tell them apart. Example: Cola--made up of water, sugar, and carbon etc, but I can't tell it's a homogenous mixture just by looking at it

Dough is a homogeneous mixture of Flour, Water and salt etc. It is a physical mixture. No chemical reaction has taken place. Alloy is a intimate , homogeneous physical mixture of metals. Reaction does not take place. So alloy is not a compound but it is a homoegneous mixture...

A mixture is basically substances distributed through each other with no covalent or ionic bonding. A compound is when the constituent elements are bonded together either covalently (like water) or ionically (like salt).

homogeneous means a mixture which can be seperated easily... alloy is a mixture of many metals... and is a homogeneous mixture too

homogeneous mixture means chemically combined and alloy is a mixture of 2 or more types of metal or non metal in certain, specific ratio => alloy is a mixture

Homogeneous means that there is only one phase present - ie the whole material is solid (or liquid, or gas). Mixture means that each metal can be present in any proportion. If an alloy was a compound, you could only get one ratio of metals present, whereas in reality you can go from 0% to 100% of each metal in an alloy.

read it carefully and slowly ---> alloy - is a homogeneous mixture of two or more metals or non metals. mixture because its components are not chemically combined together for eg. a mix of sand and salt < u cant separate the two though they are not chemically combined . homogeneous because it has constant composition of the constituted metals throughout it . for eg dissolve sugar in water what u get is a homogeneous mixture ----as sugar is uniformly distributed in water. now mix oil and water --oil will float on water > what u get is a heterogeneous mixture > with a visible boundary between oil and water and the two can be easily separated . so NOW--- alloy is a homogeneous mixture of two or more metals or non metals.
