Do chlorates decompose when heated? + Example
Yes. Chlorates are ionic compounds that contain the chlorate anion, "ClO"_3^(-), and the ion of a metal. When heated, these compounds undergo decomposition to form oxygen gas, "O"_2, and a metal chloride. The classic example is the decomposition of potassium chlorate, "KClO"_3, to oxygen gas and potassium chloride, KCl". "KClO"_text(3(s]) -> "KCl"_text((s]) + "O"_text(2(g]) uarr If you want
