2KClO3 ----> 2KCl + 3O2
The equation as given can not be balanced, because it is incomplete: When hydrogen peroxide decomposes to produce water, it also produces oxygen. A proper, balanced equation for the reaction is 2 H2O2 -> 2 H2O + O2.
2Li + O --> Li2O
4K + O2 = 2K2O so the "coefficient" is 1
A balanced equation has equal numbers of each type of atom on each side of the equation..The chemical equation describes the balanced reaction between lead and oxygen to form lead oxide is as follows .4Pb + 3O2 → 2Pb2O3.
2KClO3 ----> 2KCl + 3O2

Decomposes into metallic silver and oxygen.
The atomic oxygen is O.
Unbalanced Equation: KClO3 ===> KCl + O2 Balanced Equation: 2KClO3 ===> 2KCl + 3O2
Kn2 heat equal kn2+o2
That would be Magnesium Oxide (since a single element cannot decompose) which decomposes into Magnesium and Oxygen. Magnesium Oxide --> Magnesium + Oxygen or the balanced chem. equation: 2MgO --> 2Mg + 02
2KNO3 (s) ==heat==> 2KNO2(s) + O2(g) potassium nitrate decomposes to potassium nitrite and oxygen. NB Note the spelling for the product.
2Li + O --> Li2O
The complete combustion of ethanol in oxygen proceeds according to the balanced equation C2H6O + 3 O2 -> 2 CO2 + 3 H2O.
If the equation has the same number of each type of atom on both sides of the arrow, it is balanced. If the number of atoms on each side of the arrow is not the same, the equation is not balanced. For example, in the equation H2 + O2 -->H2O, there are two hydrogen atoms and two oxygen atoms on the left, and two hydrogen atoms and one oxygen atom on the right. Therefore, the equation is not balanced. However, in the equation 2H2 + O2 -->2H2O, there are four hydrogen atoms and two oxygen atoms on the left and four hydrogen atoms and two oxygen atoms on the right, so the equation is balanced.
4K + O2 = 2K2O so the "coefficient" is 1
