Silicon & oxygen.
Sand in water is a heterogeneous mixture. The sand does not dissolve in the water, and the two components can be visibly distinguished.
Common glass is made from sand, SiO2, Na2O and CaO. Concrete is a mixture of rocks (aggregate), sand, and water.
Silica.
Sand and oil can be separated by a technique called sedimentation and decantation. When mixed with water, sand will settle at the bottom due to its high density, while oil will float on top of the water. By carefully pouring off the oil layer, the two components can be separated.
Silicon and oxygen are the two elements that you combine to make sand. =]
If your mixture is sand and salt, separating the two will give you sand and salt.Whatever the mixture is made of, separating the components will give you the components
Sand in water is a heterogeneous mixture. The sand does not dissolve in the water, and the two components can be visibly distinguished.
Screening rocks from sand is a physical change because it does not alter the chemical composition of the rocks or sand. It simply separates the two components based on their physical properties, such as size and shape.
The two main components of soil are organic matter, such as decaying plant and animal material, and inorganic matter, such as minerals and rocks. These components provide essential nutrients and structure for plant growth.
No, aluminum is an element. A common form of sand is silicon dioxide, a compound of two elements neither of which is aluminum.
Mixing clay and sand in a test tube will result in a heterogeneous mixture, as the clay particles will not dissolve in the sand. The two components can be physically separated by techniques such as filtration or sedimentation.
Sandstone primarily consists of two components: sand grains and a cementing material. The sand grains are typically made of quartz or feldspar, while the cement can be composed of minerals such as silica, calcite, or iron oxide that bind the grains together. This combination gives sandstone its characteristic texture and durability.

Water and sand
The filtration process separates sand particles from water, leaving behind impurities in the sand. As a result, the filtrate of sand and water is considered pure because the sand acts as a physical barrier, preventing impurities from passing through with the water. This allows for the separation of the two components, producing a cleaner filtrate.
