Question

Which of the following best describes glucose (C₆H₁₂O₆)?

1) It is an atom
2) It is an ion
3) It is both a molecule and a compound
4) It is a molecule but not a compound

Answer 1

Step-by-step explanation:

The correct answer is:

3) It is both a molecule and a compound

Step-by-step explanation:

- Glucose (C₆H₁₂O₆) is a molecule because it is made up of two or more atoms chemically bonded together. In this case, glucose is composed of carbon (C), hydrogen (H), and oxygen (O) atoms.

- Glucose is also a compound because it consists of two or more different elements (carbon, hydrogen, and oxygen) chemically combined in a fixed ratio. A compound is a substance formed when atoms of different elements are bonded together.

So, glucose is both a molecule (because it is composed of atoms) and a compound (because it consists of different elements).
