Here is an explanation:
It is a mixture because its contents can be separated through centrifugation and also there is no formula for it...
Check New School Chemistry, Page 13
Smoke and fog (Smog)
Dirt and water (Mud)
Sand, water and gravel (Cement)
Water and salt (Sea water)
Potassium nitrate, sulfur, and carbon (Gunpowder)
Oxygen and water (Sea foam)
Petroleum, hydrocarbons, and fuel additives (Gasoline)
sand is nt a mixture but a compound because it has 2 constituent element such as silicon and oxygen and( a compound is a chemical substance formed when two or more elements re chemically combined in a fixed proportion by mass
that means the answer is blood
Sand is also a mixture. It's a heterogenous mixture
The main component of sand is SiO2
, silicon dioxide. If you purified the sand, you could obtain a pure compound, but in general, natural deposits of sand have SiO2
and a lot of other "stuff" (e.g. organic molecules, iron oxides, and even biological matter), which is called a mixture.
Sand is a naturally occurring granular material composed of finely divided rock and mineral particles. It is not a compound or an element, but rather a mixture of various minerals and rock fragments. The composition of sand can vary depending on its source, but common components include quartz, feldspar, mica, and other minerals.
blood is the answer because there is no formular to present the contituent of blood
Both sand and blood are mixtures and can be separated by physical means references essential chemistry page 13 to 14
Blood is a compund oo.. Is there any way the elements of Blood can be separated? I think the answer is Sand.
