2KClO3 ----> 2KCl + 3O2
2KF -> 2K + F2
Oxygen can be prepared in the laboratory by heating potassium chlorate (KClO3). When potassium chlorate is heated, it decomposes to form potassium chloride (KCl) and oxygen gas (O2). The balanced chemical equation for this reaction is: 2KClO3(s) -> 2KCl(s) + 3O2(g)
The word equation for potassium burning in oxygen is: potassium + oxygen -> potassium oxide. The balanced chemical equation for this reaction is: 4K + O2 -> 2K2O.
The balanced symbol equation for potassium and oxygen is: 4K + O2 -> 2K2O
The balanced chemical equation for potassium chloride is 2KCl = 2K + Cl2.
2KF -> 2K + F2
Kn2 heat equal kn2+o2
Oxygen can be prepared in the laboratory by heating potassium chlorate (KClO3). When potassium chlorate is heated, it decomposes to form potassium chloride (KCl) and oxygen gas (O2). The balanced chemical equation for this reaction is: 2KClO3(s) -> 2KCl(s) + 3O2(g)
2KNO3 (s) ==heat==> 2KNO2(s) + O2(g) potassium nitrate decomposes to potassium nitrite and oxygen. NB Note the spelling for the product.
The word equation for potassium burning in oxygen is: potassium + oxygen -> potassium oxide. The balanced chemical equation for this reaction is: 4K + O2 -> 2K2O.
The balanced equation for potassium reacting with chlorine to form potassium chloride is: 2K + Cl2 → 2KCl
The balanced symbol equation for potassium and oxygen is: 4K + O2 -> 2K2O
The balanced chemical equation for potassium chloride is 2KCl = 2K + Cl2.
The balanced equation for this reaction is: 2 KClO3 -> KClO4 + KCl
Potassium nitrate is too stable and so is silver for these two species to react. There is thus no balanced equation.
2K + Cl2 ---> 2KCl
The balanced equation for heated potassium chlorate decomposing into oxygen and potassium chloride is: 2KClO3(s) -> 2KCl(s) + 3O2(g)
