Answer 2

The chemical equation you provided is not balanced. Let's balance it step by step:

Initial equation: C + KNO3 → K2CO3 + CO2 + O2

1. Balance the number of atoms of each element on both sides of the equation: C: 1 on the left, 1 in K2CO3, and 1 in CO2 on the right. K: 1 in KNO3 on the left, 2 in K2CO3 on the right. N: 1 in KNO3 on the left. O: 3 in KNO3 on the left, 3 in K2CO3, and 2 in CO2 on the right.

Balanced equation: C + KNO3 → K2CO3 + CO2 + O2

2. Balance oxygen atoms by adding appropriate coefficients: C + KNO3 → K2CO3 + 2CO2 + O2

Now, let's balance the nitrogen atoms:

3. Add a coefficient of 2 in front of KNO3 to balance nitrogen: C + 2KNO3 → K2CO3 + 2CO2 + O2

Finally, balance the potassium atoms:

4. Add a coefficient of 2 in front of K2CO3 to balance potassium: C + 2KNO3 → 2K2CO3 + 2CO2 + O2

The balanced chemical equation is:

C + 2KNO3 → 2K2CO3 + 2CO2 + O2

This reaction represents the decomposition of potassium nitrate (KNO3) into potassium carbonate (K2CO3), carbon dioxide (CO2), and oxygen (O2).
