Question

S-->SO3-->H2SO4-->H2O

Answer 1

S+O2=SO2

2SO2+O2=2SO3

SO3+H2O=H2SO4

H2SO4=(t°C)SO3+H2O

Answer 2

The expression you provided appears to be a series of chemical reactions involving sulfur dioxide (SO2) and water (H2O) leading to the formation of sulfuric acid (H2SO4). Let's break down the reactions step by step:

1. SO2 (sulfur dioxide) reacts with O2 (oxygen) in the presence of a catalyst to form SO3 (sulfur trioxide). The balanced chemical equation for this reaction is:

2 SO2 + O2 → 2 SO3

2. SO3 (sulfur trioxide) reacts with water (H2O) to produce sulfuric acid (H2SO4). This is an exothermic reaction and is highly acidic in nature. The balanced chemical equation for this reaction is:

SO3 + H2O → H2SO4

So, overall, the reactions can be summarized as follows:

SO2 + O2 → SO3 SO3 + H2O → H2SO4

The final product is sulfuric acid (H2SO4), which is a strong mineral acid commonly used in various industrial processes and laboratories.
