Is sand a mixture or a compound? I was given an assignment to find out if sand is a mixture or a compound I'm sure it can't be an element. Considering the fact that a mixture contains two or more substances that are not chemically combined and not proportionally fixed and a compound is contained substances that are chemical combined and are fixed proportionally. Sand contains a lot of divided small rocks and mineral particles.
Sand is a mixture. Sand is classified as a heterogeneous mixture because it does not have the same properties, composition and appearance throughout the mixture. A homogeneous mixture has a uniform mix throughout.
