Is sidewalk cement an element or a compound? Please help immediately!!! :(
Sidewalks are made of concrete. Cement is just a part of concrete.

What is the difference between cement and concrete? Although the terms cement and concrete often are used interchangeably, cement is actually an ingredient of concrete. Concrete is a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone; the paste is water and portland cement.
Sidewalk cement, also known as concrete, is not an element. It is actually a compound. Cement is made by mixing different compounds, such as limestone, clay, and other minerals, with water. These compounds react chemically to form a solid material called cement. When cement is mixed with aggregates like sand and gravel, it forms concrete, which is the material used for sidewalks, buildings, and other structures.
To determine whether something is an element or a compound, you need to understand the difference between the two. An element is a substance that consists of only one type of atom, such as oxygen or gold. On the other hand, a compound is a substance made up of two or more different elements chemically combined together, like water (H2O) or carbon dioxide (CO2).
In the case of sidewalk cement, it is a compound because it is made up of multiple elements (such as calcium, silicon, oxygen, and others) chemically bonded together to form a new substance.
