Answer:
Step-by-step explanation:
A compound is a substance made up of two or more distinct elements that are chemically linked to one another in chemistry. These components mix in predetermined ratios to produce a special set of attributes that are distinct from those of the individual components. Chemical reactions such as combination, breakdown, or exchange reactions can all result in the formation of compounds. Water (H2O), sodium chloride (NaCl), and carbon dioxide (CO2) are a few examples of compounds. Chemistry is based on the understanding of the composition and behavior of compounds, which is essential for many applications in science and technology.
All three statements are true:
- A compound can be formed by two or more atoms of the same element. (ex - NaCl)
- A compound can be formed by a chemical combination of one particular element. (ex - FeS)
- A compound can be formed by a reaction between two or more distinct kinds of atoms. (ex -
