Certainly! Let's address each part of the question step by step.
### 2. In the equation, [tex]\(CO_2\)[/tex] is a [tex]$\square$[/tex]
- Step 1: Identify the chemical [tex]\(CO_2\)[/tex]. [tex]\(CO_2\)[/tex] stands for carbon dioxide.
- Step 2: Recognize what carbon dioxide represents in chemistry.
- A compound is a substance made up of two or more different elements that are chemically bonded together. Carbon dioxide consists of one carbon atom (C) and two oxygen atoms (O), fitting the definition of a compound.
Hence, in the equation, [tex]\(CO_2\)[/tex] is a compound.
### 3. In the equation, [tex]\(C_6H_{12}O_6\)[/tex] is a [tex]$\square$[/tex]
- Step 1: Identify the chemical [tex]\(C_6H_{12}O_6\)[/tex]. [tex]\(C_6H_{12}O_6\)[/tex] represents glucose, a common sugar.
- Step 2: Understand what glucose represents in terms of chemical structure.
- A molecule is the smallest unit of a chemical compound that can exist; it is made up of two or more atoms. Glucose is made up of six carbon atoms (C), twelve hydrogen atoms (H), and six oxygen atoms (O), fitting the definition of a molecule.
Therefore, in the equation, [tex]\(C_6H_{12}O_6\)[/tex] is a molecule.
### 4. In [tex]\(O_2\)[/tex], the type of bond that holds the two oxygen atoms together is a [tex]$\square$[/tex]
- Step 1: Identify the chemical [tex]\(O_2\)[/tex]. [tex]\(O_2\)[/tex] stands for molecular oxygen, which is the form of oxygen that we breathe.
- Step 2: Understand the type of bond present in [tex]\(O_2\)[/tex].
- The oxygen molecule consists of two oxygen atoms sharing electrons. The bond is characterized as a double bond because two pairs of electrons are shared between the oxygen atoms.
Thus, in [tex]\(O_2\)[/tex], the type of bond that holds the two oxygen atoms together is a double bond.
### Conclusion
To summarize:
- [tex]\(CO_2\)[/tex] is a compound.
- [tex]\(C_6H_{12}O_6\)[/tex] is a molecule.
- In [tex]\(O_2\)[/tex], the type of bond that holds the two oxygen atoms together is a double bond.
