Balanced Chemical Equation

The balanced chemical equation for the reaction between hydrated ferric chloride (FeCl3. 6H2O) and thionyl chloride is:

FeCl3. 6H2O + 2SOCl2 → FeCl3 + 2SO2 + 12HCl

Number of SO2 Molecules

The coefficient of SO2 in the balanced chemical equation is 2. However, it is important to note that two molecules of thionyl chloride (SOCl2) are required to produce one molecule of SO2. Therefore, we need to multiply the coefficient of SO2 by 2 to get the actual number of SO2 molecules involved in the reaction.

2SOCl2 → 2SO2 + Cl2

As we can see from the above equation, two molecules of SOCl2 produce two molecules of SO2. Therefore, the number of SO2 molecules involved in the balanced chemical equation for the reaction between hydrated ferric chloride and thionyl chloride is:

2 × 2 = 6

Therefore, the correct answer is 6.
