# Find X in this Reaction FeCl + HO

In X of reacts Fe Cl3 + H2O + X
–> Fecl2 + H2SO4 +HCI _______

• S
• H2S
• SO2
• SO3
1 Answer(s)

Balanced equation:

2FeCl3 + 2 H2O + SO2  = 2FeCl2 + 2HCl + H2So4

Hence, the X = SO2

Instruction on balancing chemical reaction:-

• Always use the upper case for the first character in the element name and the lower case for the second character
• To enter an electron into a chemical equation use {-} or e
• To enter an ion specify charge after the compound in curly brackets: {+3} or {3+} or {3}.
Example: Fe{3+} + I{-} = Fe{2+} + I2
• Substitute immutable groups in chemical compounds to avoid ambiguity.
Compound states
• If you do not know what products are enter reagents only and click ‘Balance’. In many cases a complete equation will be suggested.
• Reaction stoichiometry could be computed for a balanced equation. Enter either the number of moles or weight for one of the compounds to compute the rest.
