Answer:
1K2CO3 —> 1K2O + CO2
Step-by-step explanation:
The equation is already balanced. We can check by counting the amount of each element on each side of the equation:
_K2CO3 —> _K2O + CO2
Products Side:
• K: 2
• C: 1
• O: 3
Reactants Side:
• K: 2
• C: 1
• O: 3
Since everything matches, we can just put a coefficient of 1 in front of each potassium.
1K2CO3 —> 1K2O + CO2
