what is the chemical reaction equation for : Hydrogen sulfite reacts with oxygen to form sulfur dioxide and water vapour.

Are you sure you don't mean hydrogen sulfiDe (H2S) ? Hydrogen sulfiTe would be sulfurous acid (H2SO3), which can decompose directly into H2O and SO2.

For the oxidation of H2S,

2 H2S + 3 O2 -> 2 SO2 + 2 H2O

2H2S(g)+3O2(g)→2SO2(g)+2H2O(g)

To determine the chemical reaction equation for the given statement, we need to identify the chemical formula for each compound involved.

The chemical formula for hydrogen sulfite is H2SO3, and the chemical formula for sulfur dioxide is SO2. The chemical formula for water vapor is H2O, and oxygen is simply O2.

Now, let's write the balanced chemical equation for the reaction:

H2SO3 + O2 → SO2 + H2O

In this equation, we have 2 hydrogen atoms on both sides, 1 sulfur atom on both sides, and 4 oxygen atoms on both sides, meaning the equation is balanced.

To obtain this equation, it's important to know the chemical formulas of the compounds involved, as well as understanding the concept of balancing chemical equations.
