The main constituent of sand is Silicon Dioxide. This compound contains silicon and oxygen.
The preponderance of the elements in sand are silicon or oxygen, with twice as many oxygen atoms as silicon atoms. In naturally occurring sand, some impurities with additional elements as iron are usually present in small amounts.
Stone and sand.
The purest sand is a compound, silicon dioxide. Most ordinary sand, however would contain some other materials and could be either a homogeneous or a heterogeneous mixture.
compoundIf the iron fillings are pure, they contain only one type of atom (all the atoms have the same number of protons). Thus, the filings would be a sample of the element iron. If the filings are rusty, then they would contain compounds (iron oxides).
It's a compound. H2O - Two hydrogen atoms, one oxygen atom Water is a compound as it can be reduced to simpler elements (Oxygen and water).It is a homogenous mixture("the same") as it is uniform throughout. E.g: Salt and sand mixed together would be a heterogenous mixture("different") as you can distinguish between sand and salt. A pure 'mixture' is usually homogenous, especially liquids.
No, aluminum is an element. A common form of sand is silicon dioxide, a compound of two elements neither of which is aluminum.

Sand is mainly made up of Silicon dioxide. The elements making this compound are Silicon and Oxygen. SiO2 is a very hard compound.
Sand is primarily composed of small particles of silica, which is a compound made up of silicon and oxygen. Other common elements found in sand include minerals such as feldspar, mica, and quartz. The specific composition of sand can vary depending on its source and location.
Stone and sand.
silicon and oxygen
It depends upon the source of the sand. Mostly sand is Silicon and Oxygen, but it could contain iron and other metallic elements.
The purest sand is a compound, silicon dioxide. Most ordinary sand, however would contain some other materials and could be either a homogeneous or a heterogeneous mixture.
Silicon dioxide is the main component of sand, but it is not the only compound present. Sand may also contain other minerals like quartz, feldspar, and mica, as well as traces of other substances depending on the source of the sand.
Sand is a mixture, not a compound, as it is made up of different elements such as silicon, oxygen, and occasionally other minerals. These elements are not chemically bonded together in a specific ratio to form a new substance.
Silicon and oxygen are the two elements that you combine to make sand. =]
