A number of substances and their chemical formulas are listed below. Check the ones that are compounds.

- Neon [tex]$(\text{Ne})$[/tex]
- Carbon monoxide [tex]$(\text{CO})$[/tex]
- Glucose [tex]$\left(\text{C}_6\text{H}_{12}\text{O}_6\right)$[/tex]
- Cobalt [tex]$(\text{Co})$[/tex]
- Fluorine [tex]$(\text{F}_2)$[/tex]



Answer :

To determine which substances are compounds from the given list, we need to understand that a compound is composed of more than one type of element. Here's the given list with their chemical formulas:

1. Neon (Ne)
2. Carbon monoxide (CO)
3. Glucose (C₆H₁₂O₆)
4. Cobalt (Co)
5. Fluorine (F₂)

Let's analyze each substance step-by-step:

1. Neon (Ne):
- Formula: Ne
- Neon consists of only one type of element, which is Neon itself.
- Neon is not a compound.

2. Carbon monoxide (CO):
- Formula: CO
- Carbon monoxide consists of two different types of elements: Carbon (C) and Oxygen (O).
- Carbon monoxide is a compound.

3. Glucose (C₆H₁₂O₆):
- Formula: C₆H₁₂O₆
- Glucose consists of three different types of elements: Carbon (C), Hydrogen (H), and Oxygen (O).
- Glucose is a compound.

4. Cobalt (Co):
- Formula: Co
- Cobalt consists of only one type of element, which is Cobalt itself.
- Cobalt is not a compound.

5. Fluorine (F₂):
- Formula: F₂
- Fluorine consists of only one type of element, which is Fluorine itself, even though it has two atoms of the same element.
- Fluorine is not a compound.

Thus, the substances that are compounds from the list are carbon monoxide and glucose.
