First calculate the molar mass of the potassium chlorate
KClO3 K is 39.1, Cl is 35.45 and O is 16 x 3 =48
The molar mass for one mol is 122.55g/mol
The percent composition is the part the oxygen contributed divided by the total molar mass times 100(to convert a decimal to a percent)
48/122.55 x 100 is 39.167%
Potassium Chlorate is 39.167 percent oxygen
I believe it is: %O=mass of 3 mol of O / mass of 1 mol of potassium chlorate *100% If you measured it: %O=mass of oxygen lost / mass of potassium chlorate *100%
Potassium Chlorate, when heated gives Potassium Chloride and Oxygen. You can use Manganese Dioxide as a catalyst to speed up the reaction.
Potassium chlorate contains potassium, chlorine, and oxygen. It is used in safety matches, explosives, as an oxidizing agent, to prepare oxygen, and as a disinfectant.
Oxygen
Potassium chlorate is a compound containing potassium, chlorine, and oxygen atoms. It's molecular formula is KClO3.
I believe it is: %O=mass of 3 mol of O / mass of 1 mol of potassium chlorate *100% If you measured it: %O=mass of oxygen lost / mass of potassium chlorate *100%
Potassium chlorate is KClO3 and it consists of potassium, chlorine and oxygen.
Potassium chlorate (KClO3) has 3 oxygen atoms.
potassium, chloride and oxygen
Oxygen is present in both zinc nitrate and potassium chlorate. Potassium chlorate = KClO3 and zinc nitrate = ZnNO3 .
The answer is 1 mole potassium chlorate.
Potassium Chlorate, when heated gives Potassium Chloride and Oxygen. You can use Manganese Dioxide as a catalyst to speed up the reaction.
Potassium chlorate contains potassium, chlorine, and oxygen. It is used in safety matches, explosives, as an oxidizing agent, to prepare oxygen, and as a disinfectant.
Nothing is produced, 500g potassium chlorate will be the same 500 g potassium chlorate after reaction. Actually there is no reaction at all.
it is used to prepare oxygen
Pure oxygen gas can be prepared in the laboratory by the decomposition of solid potassium chlorate to form solid potassium chloride and oxygen gas. 34.0 g
Four moles of potassium chlorate are needed.
