Is Heating potassium chlorate a chemical or physical change?
Heating anything to a visible change is ALWAYS a chemical change
What happens when heating potassium chlorate?
Potassium nitrate also known as salt petre is a chemical compound with the formula KNO3 which on heating to above 560 °C decomposes into potassium nitrite, and oxygen.given by the following chemical equation-2 KNO3 → 2 KNO2 + O2
What is the mass of KCl if 9.8g of KCls is heated?
On heating potassium chlorate decomposes on potassium chloride and oxygen. 2KClO3------>2KCl+3O2 9.8g of KClO3 are heated. Calculate a. the mass of KCl formed. b. the mass and volume, at (s.t.p) of O2 formed.
What is the chemical formula for ammonium chlorate?
Ammonium chlorate is an inorganic compound with the formula NH4ClO3. ---- It is obtained by neutralizing chloric acid with either ammonia or ammonium carbonate, or by precipitating barium, strontium or calcium chlorates with ammonium carbonate or ammonium sulfate, producing the respective carbonate or sulfate precipitate and an ammonium chlorate solution. Ammonium chlorate crystallizes in small needles, readily soluble in water. On heating, ammonium chlorate decomposes at about 102 °C, with liberation of nitrogen, chlorine and oxygen. It is soluble in dilute aqueous alcohol, but insoluble in strong alcohol. This compound is a strong oxidizer and should never be stored with flammable materials. Ammonium chlorate is a very unstable oxidizer and will decompose, sometimes violently, at room temperature. It will explode when exposed to sunlight for a few minutes. Even solutions are known to be unstable. Because of the dangerous nature of this salt it should only be kept in solution when needed, and never be allowed to crystallize.
How Can you separate ammonium chloride from water?
by the process of sublimation the mixture of sodium chloride and ammonium chloride is placed in a dish and covered with an inverted funnel on heating, ammonium chloride will change into vapour,which will condense into a solid in the neck of the funnel ,whereas sodium chloride was left behind the dish
Oxygen and potassium chloride are prepared by heating potassium chlorate?
yes KClO3 + heat --> KCl + O2

Potassium chlorate--on heating potassium?
Despite that potassium chlorate catches on fire when it gets heated in the open, if you put it in a test tube and heat that, instead of burning it will melt into molten form, and this stage of potassium chlorate is extremely reactive, any contact with anything combustible like sugar would cause combustion of it. This is the basis for the famous gummy bear and potassium chlorate experiment. The sugar in the gummy bear would combust on contact with the molten potassium chlorate, resulting in an violent reaction.
In heating the mixture of potassium chlorate and manganese dioxide what is the role of the manganese dioxide?
It serves as a catalysts.
Potassium chlorate is a rich source of oxygen It decomposes upon heating to produce potassium chloride and oxygen What is the correctly balanced equation for this reaction?
2KClO3 ----> 2KCl + 3O2
What make up O2?
Oxygen gas is never found in a monomer (O), but is always found in either the dimer form (O2), or the trimer form ozone (O3).O2 can be made by heating potassium chlorate(v) and manganese(iv) oxide.This can be used to make oxygen for scince experiments.This is because Potassium chlorate is a compound containing pottasium, chlorine and oxygen, with the molecular formula KClO3.Manganese(IV) oxide is the inorganic compound with the formula MnO2.
Where is oxygen obtained from?
"Oxygen is obtained for industrial use by the fractional distillation of liquid air, by the electrolysis of water, or by heating manganese oxide with potassium chlorate.

Is potassium metal used as a heating element?
No. Potassium metal is to reactive and expensive for everyday use.
Which gas evolved on heating sodium carbonate?
carbondioxide
