What are three differences between a compound and a mixture?

a compound always results from combination due to cheical change. the chemical properties of substances change when they undergo chemical reaction, that is donation and sharing of bonding electrons. so carbon dioxide is a compound since one carbon atom shares electrons with two oxygen atoms. a mixture demonstrates only changes in the physical properties of the mixing substances. sugar in water only makes the water sweet, but it is still just H20 mixed with molecules of sugar gone extremely tiny due to dissolution. no electron bonding. A compound is only a certain type of combination of different elements, such as CO2. A mixture is 2 or more elements or compounds mixed together but not chemically combined (such as air). I really hope this helps!!

Compounds are bonded atoms. Mixtures are just stuff thrown together. Pretty much any two materials can be thrown together to make a mixture. Most combinations of atoms will not form compounds. Even though the list of possible compounds is very large, the list of impossible compounds is infinitely larger. Mixtures can be mechanically separated. Compounds require a chemical reaction to separate.

A compound is defined as any two species chemically combined whereas a mixture is a bunch of species moving past each other w/o chemically combining. Kind of confusing and hard to process isn't it?! Chem is hard. Think of it like amonnia NH3 compared to N and the H and H and H not combining under the "right conditions"

a compound is many things put into different piles a mixture is those many things mixed together in one [pile

a compoud is two or more chemicals chemically combined while a mixture is two substances just mixed together.

compound= two substances combined Mixture= two or more substances mixed together to make one whole new thing
