What changes occurs when KClO3 is heated in the presence of MnO2?
When KClO3 is heated in the presence of MnO2, it undergoes a decomposition reaction to produce potassium chloride (KCl) and oxygen gas (O2). The manganese dioxide (MnO2) acts as a catalyst, speeding up the reaction but remains unchanged itself.
How much KClO3 must be heated to produce as much O2 as would be obtained from 50 gm og HgO?
68 g of KClO3 must be heated to produce as much O2 as would be obtained from 50 g of HgO.
Rank these items in order of increasing oxidation number for manganese Mn KMnO4 MnO2?
MnO2: oxidation number +4KMnO4: oxidation number +7
What is the charge of MnO2?
The charge of MnO2 is typically +4 because oxygen is typically assigned a charge of -2, and there are two oxygen atoms in MnO2. This means the manganese atom in MnO2 must have a charge of +4 to balance the charges.
What is the reaction between h2so3 plus kclo3 equals?
The reaction between H2SO3 and KClO3 does not occur. H2SO3 is a weak acid, and KClO3 is a salt. There is no precipitation, gas evolution, or significant heat release that would indicate a chemical reaction taking place between these two substances.

Is heating KClO3 and MnO2 a chemical or physical change?
Heating KClO3 and MnO2 to form KCl and MnO2 is a chemical change as new substances are being produced.
Why must KClO3-MnO2 mixture be kept away from rubber stopper?
KCIO3-MNO2 cannot comes in contact with the rubber stopper otherwise, or a severe explosion may result.
Substance that yield oxygen when heated?
KClO3
What chemical is used to prepare oxygen gas by heating process?
This chemical reaction is:2 KClO3 --------------(MnO2)---------------2 KCl + 3 O2
Balance manganese dioxide and potassium chlorate?
Balance manganese dioxide and potassium chlorate is as follows . the formula for potassium chlorate is KClO3 and the one for manganese dioxide is MnO2.so, the reaction is :2 KClO3(s)-> 2 KCl(s)+3 O2(g).
How much KClO3 must be heated to produce as much O2 as would be obtained from 50 gm og HgO?
68 g of KClO3 must be heated to produce as much O2 as would be obtained from 50 g of HgO.
Why must KClO3-MnO2 mixture be kept away from the rubber stopper?
The mixture of KClO3 and MnO2 can react vigorously and release oxygen gas under certain conditions. The oxygen gas produced can build up pressure inside the container, leading to a potential explosion. Rubber stoppers are not gas-impermeable and may not be able to contain the pressure, hence it is safer to use a stopper that is more appropriate for such reactions.
What volume of O2 will produce when g of KClO3 is heated at NTP?
3 moles of oxygen are obtained from 2 moles of potassium chlorate.M of KClO3 is 122,55 g, M of O2 is 32, density of oxygen is 1,429 g/L.
What is the function of KClo3 in determination of hydrogen and carbon in sugar?
KCLO3 is used in the determination of hydrogen and carbon in sugar through a process called combustion analysis. When sugar is heated with KCLO3, it undergoes combustion, converting all carbon to CO2 and all hydrogen to H2O. By measuring the amount of CO2 and H2O produced, the amount of carbon and hydrogen in the sugar can be calculated.
What is the formula for potassium chlorate?
The formula for potassium chlorate is KClO3.
Balanced equation for potassium chlorate when heated produces potassium chloride plus oxygen gas?
This reaction is:2 KClO3 = 3 O2 + 2 KCl
