Question

KClO3->O2->SO2->SO3​

Answer 1

$2KClO_{3} = 2KCl + 3O_{2} \\ S + O_{2} = SO_{2} \\ 2SO_{2} + O_{2} = 2SO_{3}$

Answer 2

The chemical equation you provided seems to be missing some important information. It appears to be a series of chemical reactions, but the reactants and products for each step are not clear. Additionally, there might be some errors in the reaction sequence you provided. Let's try to complete the missing information and correct any mistakes:

The general idea seems to be the decomposition of potassium chlorate (KClO3) into oxygen (O2), and then the oxidation of sulfur dioxide (SO2) to sulfur trioxide (SO3).

The balanced chemical equation for the decomposition of potassium chlorate is:

2 KClO3(s) → 2 KCl(s) + 3 O2(g)

In this reaction, potassium chlorate (KClO3) decomposes into potassium chloride (KCl) and oxygen gas (O2).

Now, if we want to involve sulfur dioxide (SO2) in the reaction, we could write a separate equation for the oxidation of SO2 to SO3:

2 SO2(g) + O2(g) → 2 SO3(g)

In this reaction, sulfur dioxide (SO2) reacts with oxygen gas (O2) to produce sulfur trioxide (SO3).

If you are trying to depict a series of reactions, it's important to note that these reactions would typically occur separately. The products of the first reaction (oxygen gas, O2) might serve as a reactant in the second reaction to produce sulfur trioxide (SO3).
