Answer 2

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

C + HNO3 = K2CO3 + CO2 + N2

To balance the equation, we need to make sure that the same number of each type of atom appears on both sides of the equation.

1. Balance the carbon (C) atoms: There is one carbon atom on the left side (C) and one on the right side (in K2CO3). So, the carbon atoms are already balanced.

2. Balance the hydrogen (H) atoms: There is one hydrogen atom on the left side (H) and none on the right side. To balance it, we need to add H2O on the right side.

C + HNO3 = K2CO3 + CO2 + N2 + H2O

3. Balance the oxygen (O) atoms: On the left side, there are three oxygen atoms from HNO3, and on the right side, there are two from CO2 and two from K2CO3. In total, there are 4 oxygen atoms on the right side. To balance, we can add two more H2O molecules on the right side.

C + HNO3 = K2CO3 + CO2 + N2 + 2 H2O

4. Balance the nitrogen (N) atoms: On the left side, there is one nitrogen atom from HNO3. On the right side, there is one from N2. So, nitrogen atoms are already balanced.

Now the balanced chemical equation is:

C + 4 HNO3 = K2CO3 + CO2 + N2 + 2 H2O

Keep in mind that this equation represents a chemical reaction, but without further context or specific conditions, it's challenging to determine if this reaction is feasible or realistic. Additionally, the products K2CO3 (potassium carbonate) and N2 (nitrogen gas) might not be typical products of this particular reaction. Please double-check the reaction to ensure it is correct for your specific context.
