To solve the problem of balancing the given unbalanced chemical equation [tex]\( \text{CO}_2 + \text{C} \rightarrow \text{CO} \)[/tex]:

We need to ensure that the number of each type of atom on the reactants side is equal to the number on the products side. Let's analyze each option given:

Option A: [tex]\( \text{CO}_2 + \text{C} \rightarrow 2 \text{CO} \)[/tex]

- Reactants:
- Carbon (C): [tex]\(1 \text{ C from CO}_2 + 1 \text{ C from C} = 2 \text{ C atoms}\)[/tex]
- Oxygen (O): [tex]\(2 \text{ O atoms from CO}_2\)[/tex]

- Products:
- Carbon (C): [tex]\(2 \text{ C atoms from 2 CO}\)[/tex]
- Oxygen (O): [tex]\(2 \text{ O atoms from 2 CO}\)[/tex]

Both sides have 2 carbon atoms and 2 oxygen atoms. Thus, this equation is balanced.

Option B: [tex]\(2 \text{CO}_2 + \text{C} \rightarrow \text{CO} \)[/tex]

- Reactants:
- Carbon (C): [tex]\(2 \text{ C atoms from 2 CO}_2 + 1 \text{ C from C} = 3 \text{ C atoms}\)[/tex]
- Oxygen (O): [tex]\(2 \text{ CO}_2 \cdot 2 = 4 \text{ O atoms}\)[/tex]

- Products:
- Carbon (C): [tex]\(1 \text{ C atom from CO}\)[/tex]
- Oxygen (O): [tex]\(1 \text{ O atom from CO}\)[/tex]

The number of carbon and oxygen atoms are not balanced. Thus, this equation is not balanced.

Option C: [tex]\( \text{CO}_2 + \text{C} \rightarrow \text{C}_2\text{O} \)[/tex]

- Reactants:
- Carbon (C): [tex]\(1 \text{ C from CO}_2 + 1 \text{ C from C} = 2 \text{ C atoms}\)[/tex]
- Oxygen (O): [tex]\(2 \text{ O atoms from CO}_2\)[/tex]

- Products:
- Carbon (C): [tex]\(2 \text{ C atoms from C}_2\text{O}\)[/tex]
- Oxygen (O): [tex]\(1 \text{ O atom from C}_2\text{O}\)[/tex]

The number of oxygen atoms are not balanced. Thus, this equation is not balanced.

Option D: [tex]\( \text{CO}_2 + \text{C}_2 \rightarrow \text{CO} \)[/tex]

- Reactants:
- Carbon (C): [tex]\(1 \text{ C from CO}_2 + 2 \text{ C atoms from C}_2 = 3 \text{ C atoms}\)[/tex]
- Oxygen (O): [tex]\(2 \text{ O atoms from CO}_2\)[/tex]

- Products:
- Carbon (C): [tex]\(1 \text{ C atom from CO}\)[/tex]
- Oxygen (O): [tex]\(1 \text{ O atom from CO}\)[/tex]

The number of carbon and oxygen atoms are not balanced. Thus, this equation is not balanced.

After examining all options, we conclude that:

The correct balanced form of the equation is:

Option A: [tex]\( \text{CO}_2 + \text{C} \rightarrow 2 \text{CO} \)[/tex]
