Final answer:
The chemical formula for the first carbohydrate molecule shown is C6H12O6, which represents glucose, a hexose monosaccharide. Option A is correct.
Step-by-step explanation:
The chemical formula for the first carbohydrate molecule shown is C6H12O6. This represents the molecule glucose, which is a hexose monosaccharide. In carbohydrates, the ratio of carbon to hydrogen to oxygen is 1:2:1. Glucose is an important energy source in living organisms.
The chemical formula for the first carbohydrate molecule shown is C6H12O6. This is because the stoichiometric formula for carbohydrates is represented as (CH2O)n, where n is the number of carbon atoms. In carbohydrates, the ratio of carbon to hydrogen to oxygen is 1:2:1. As such, with glucose being a monosaccharide with six carbon atoms, the resulting molecular formula is C6H12O6. This formula is synonymous with glucose, a hexose monosaccharide, which is a simple sugar and a basic unit of carbohydrates.
