Si + CO₂ → SiC + SiO₂

This reaction is not balanced. Here's how to balance it:

1. Count the atoms on each side:

* Reactants: 1 Si, 1 C, 2 O

* Products: 1 Si, 1 C, 3 O

2. Adjust coefficients to balance the atoms:

* Silicon (Si): Already balanced.

* Carbon (C): Already balanced.

* Oxygen (O): We need 2 oxygen atoms on the reactant side to match the 2 oxygen atoms on the product side. We can achieve this by multiplying CO₂ by 2.

3. The balanced equation:

Si + 2CO₂ → SiC + 2SiO₂

Explanation:

* Silicon (Si): 1 on each side.

* Carbon (C): 2 on each side.

* Oxygen (O): 4 on each side.
