Write the chemical symbol expressions for the following reactions: Charcoal burns in oxygen—— Red phosphorus burns in air—— Sulfur burns in air—— 4 heating potassium permanganate to produce oxygen—— Heating mixture of potassium chlorate and manganese dioxide——

Write the chemical symbol expressions for the following reactions: Charcoal burns in oxygen—— Red phosphorus burns in air—— Sulfur burns in air—— 4 heating potassium permanganate to produce oxygen—— Heating mixture of potassium chlorate and manganese dioxide——

Note: the number before the letter is normal, and the number after the letter is subscript
Charcoal burns in oxygen——
C + O2 ＝ CO2
Red phosphorus burns in air——
P + O2 ＝ P2O5
Sulfur burns in air——
S +O2 ＝ SO2
4 heating potassium permanganate to produce oxygen——
2KMnO4 ＝ 2KMnO3 + O2
Heating mixture of potassium chlorate and manganese dioxide——
2kclo3 = 2KCL + 3O2
OK?
