What changes occurs when KClO3 is heated in the presence of MnO2?
2KClO3(s)+MnO2(s) → 2KCL(s)+3O2(g)
What is the reaction between h2so3 plus kclo3 equals?
KClO3+3H2SO3=KCl+3H2SO4
What type of substance is MnO2?
MnO2 is a black solid oxide of manganese with catalytic applications.
Rank these items in order of increasing oxidation number for manganese Mn KMnO4 MnO2?
MnO2: oxidation number +4KMnO4: oxidation number +7
What is manganese dioxide?
Formula: MnO2
What changes occurs when KClO3 is heated in the presence of MnO2?
2KClO3(s)+MnO2(s) → 2KCL(s)+3O2(g)
Is heating KClO3 and MnO2 a chemical or physical change?
chemical change
Why must KClO3-MnO2 mixture be kept away from the 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
What would happen if MnO2 was mixed with KBrO3 and 9M sulfuric acid?
The reaction for MnO2 mixed with KBrO3 and 9M sulfuric acid is as follows: 2KI + MnO2 + H2SO4 --> I2 +MnSO4 + K2SO4 + 2H2O.
What would happen if MnO2 was mixed with KI and 9 M sulfuric acid?
KI+MnO2+H2SO4=KI+MnSO4+KHSO4+H2O
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.
A How many moles of O2 were produced b What percent of the mixture was KClO3 and KCl?
A 1.80-gram mixture of potassium chlorate, kclo3, and potassium chloride, kcl, was heated until all of the kclo3 had decomposed the liberated oxygen, after drying, occupied 405 ml at 25C when the barometric pressure was 745 torr. This is the problem and the questions were... a. How many moles of O2 were produced? b. What percent of the mixture was KClO3? KCl? Please help!!
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).
Potassium chlorate when heated produces potassium chloride plus oxygen gas?
2KClO3 ---(MnO2)---> 2KCl + 302 **The MnO2 goes over the arrow.
