2KClO₃ ---> 2KCl + 3O₂
2 mol 2 mol 3 mol
When 2 mol of KClO₃ decompose, 3 mol of oxygen are produced.
Calcium is the correct answer
Answer:
the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.
