No. Sand is a mixture of different substances. The term metalloid applies to a particular class of elements. One metalloid, silicon, is one of the most abundant elements in sand to the point that silicon is often extracted from sand.
Sand is silicon dioxide, formula SiO2
Sand and water mixed is a mixture. Elements are substances with only one type of atoms. Compounds are substances made up of chemically bonded particles. Since sand and water are neither of these, it must be a mixture.
A compound substance is one that is made up of two or more elements.
the chemical formula for sand is SiO2, so it is a compound, made from Silicon and Oxygen
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.
Sand is a mixture and rarely is only one compound.
Yes, a chemical compound is composed of two or more elements that are chemically bonded together in fixed proportions. The elements in a compound are held together by chemical bonds, such as ionic or covalent bonds.
A 'compound' is composed of several 'elements'. Don't confuse them with the 'atom'/'molecule' distinction - e.g. H20 is a compound because it has H and O, but Hydrogen in its natural state comes as H2 (2 H atoms), but still only ONE element (H).
A binary compound is one that is composed of two elements.
Carbon Monoxide is a compound. there is a easy way to find this out. An element has two sides, which is pure element and compound. pure element is substances you can easily find by searching thee periodic table of elements. If it's not on the table, it is compound or mixture. Compound is mixture of two elements and if more than three elements are mixed together, then is called mixture.
Two or more elements make up a compound, and oxygen has one.
