The decomposition of metallic chlorates depends on the specific metal involved. However, in general, they decompose to produce the corresponding metal chloride, oxygen gas, and sometimes other byproducts depending on the metal.

Here's a general equation for the decomposition of a metallic chlorate:

2MClO₃ → 2MCl + 3O₂

Where:

* M represents the metal.

* MClO₃ is the metallic chlorate.

* MCl is the metal chloride.

* O₂ is oxygen gas.

Specific examples:

* Potassium Chlorate (KClO₃) decomposes to Potassium Chloride (KCl) and Oxygen (O₂).

* Sodium Chlorate (NaClO₃) decomposes to Sodium Chloride (NaCl) and Oxygen (O₂).

Note:

* The decomposition of metallic chlorates is an exothermic reaction, meaning it releases heat.

* The reaction can be quite vigorous, especially with strong oxidizing agents like chlorates.

* The exact products and their proportions may vary depending on the conditions, such as temperature and pressure.

It's important to be aware of the potential hazards associated with decomposing chlorates as they can be explosive and cause severe burns.
