Question

Why do chemical combinations occur in nature ?

Answer 1

Answer:

Introducers and suppliers can obtain some chemicals from nature without any processing, such as minerals and animal milk. These ingredients meet the definition of a 'naturally-occurring chemical'. But most chemicals derived from nature need to be processed before introducers and suppliers can use them in a product.

Answer 2

Answer:

Compounds. ... When two distinct elements are chemically combined—i.e., chemical bonds form between their atoms—the result is called a chemical compound. Most elements on Earth bond with other elements to form chemical compounds, such as sodium (Na) and Chloride (Cl), which combine to form table salt (NaCl).
