Which of these is the correct balanced equation for the decomposition of Potassium Chlorate?
A$KClO_3 \rightarrow KCl + O_2$
B$2KClO_3 \rightarrow 2KCl + 3O_2$
C$KClO_3 \rightarrow KClO + O_2$
D$2KClO_3 \rightarrow K_2O + Cl_2 + O_2$
✓ Correct Answer: B — $2KClO_3 \rightarrow 2KCl + 3O_2$
The balanced decomposition of KClO3 produces KCl and Oxygen gas in a 2:2:3 molar ratio.
