|
|
chlorine and oxygen
|
|
|
carbon, helium, and oxygen
|
|

Explanation:
Detailed explanation-1: -The general chemical formula of carbohydrate is (CH2O)n. For example-in the case of glucose, substitute n=6, then the chemical formula of glucose is C6H12O6.
Detailed explanation-2: -Monosaccharides are the simplest carbohydrates; they conform to the general chemical formula (CH2O)x and are termed simple sugars. The most commonly occurring monosaccharides contain three to six carbon atoms in an unbranched single-bonded chain.
Detailed explanation-3: -Carbohydrates (also called saccharides) are molecular compounds made from just three elements: carbon, hydrogen and oxygen. Monosaccharides (e.g. glucose) and disaccharides (e.g. sucrose) are relatively small molecules.
