Which of the compounds below is an example of a network solid? o sg(s) sio2(s) mgo(s) nacl(s) o c25h52(s)

SiO₂(s) is an example of a network solid.

Explanation:

Network solids, also known as the covalent network solids, are the class of chemical compounds in which the constituting atoms are bonded covalently to form a continuous network, which extends through the material. In a network solid, there are no individual molecules and thus the whole solid is called a macromolecule.

Some of the examples of network solids are diamond and quartz.

Quartz or silicon dioxide is a three-dimensional continuous network of SiO₂ units.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
