When potassium chlorate is heated, it decomposes into potassium chloride and oxygen gas. This reaction is highly exothermic and can be accelerated by adding a catalyst such as manganese dioxide. The released oxygen gas can support combustion, making potassium chlorate a common ingredient in fireworks and matches.

When sugar is heated what happen to limewater?
When sugar is heated, it undergoes caramelization, which is the breakdown of sugar molecules at high temperatures. Limewater, which is a solution of calcium hydroxide, remains unchanged when sugar is heated as they are two separate substances and do not chemically react with each other.
What is the chemical reaction of potassium dichromate with sulfuric acid?
When potassium dichromate reacts with sulfuric acid, the following reaction takes place: K2Cr2O7 + 2H2SO4 -> Cr2(SO4)3 + K2SO4 + 2H2O + 3O2. This reaction results in the formation of chromium(III) sulfate, potassium sulfate, water, and oxygen gas as products.
What happens when concentrated sulphuric acid is heated with oxalic acid?
When concentrated sulfuric acid is heated with oxalic acid, oxidation of oxalic acid takes place, giving off carbon dioxide gas and water as byproducts. This reaction can be used to generate carbon dioxide for various applications.
What salt would form when each what strong acid strong base reactions takes place KOH HCl?
When KOH (potassium hydroxide, a strong base) reacts with HCl (hydrochloric acid, a strong acid), the salt formed is KCl (potassium chloride) along with water.
What is the formula for potassium phosphide?
Potassium is K (with a 1+ valence) and the phosphate anion is PO4 (with a 3- valence). Thus, it takes 3 K's for each PO4. The formula for potassium phosphate is K3PO4.
Reaction between potassium chlorate and red phosphorus takes place when you strike a match?
When you strike a match, the friction generates enough heat to ignite the red phosphorus on the match head. The red phosphorus then reacts with the potassium chlorate in the match head, which acts as an oxidizing agent, facilitating the combustion of the matchstick and allowing it to burn.
What changes takes place when water is heated or cooled?

Why condensation takes place?
Condensation takes place when a liquid is heated and it turns into a gas then back into a liquid after the gas hits the edge of a glass. Hope this helps.
What are some examples of oxidizing substances?
oxidizing agents are those that readily undergo reduction. two of the common ones i can name are potassium permanganate and potassium dichromate. After oxidation takes place, permanganate changes from purple to pink or colorless and dichromate changes from orange to green. REACTIONS HALF EQUATIONS(unbalanced) MnO4 ----> Mn2+ Cr2O42- ----> Cr3+
If a piece of potassium metal is dropped in water then a vigorous reaction takes place with the formation of potassium hydroxide and hydrogen gas is evolved?
Yes, it is correct.
What changes takes place when bimetallic strip is heated?
actually what happen is that the strip is curved to the outside
after atoms and molecules of gases and liquids are heated they move away from the heat . what takes their place?
ions
If a combination reaction takes place between potassium and chlorine what is the product?
The product of a combination reaction between potassium and chlorine is potassium chloride (KCl), a white crystalline substance commonly known as table salt.
What is the chemical change takes place when limestone is heated strongly?
This is a thermal decoposition: CaCO3 --------CaO + CO2
