C2v was written by a previous answerer. This would nearly be true if the double bound O stayed as a double bond, but that resonates throughout the 3 Os, therefore the symmetry is trigonal planar. So it has a c3 axis but also 3 c2's. therefore it is D3H.
SO3 is the chemical formula for sulfur trioxide.
Al+3 SO3+2 <---- these are the ions and their charges Al+3 Al+3 SO3+2 SO3+2 SO3+2 <---- the charges have to add up to zero, so two +3 aluminum ions cancel out three +2 sulfite ions. Al2(SO3)3 <--- simplify
3 and SO3 is an anion with a +1 charge
Cr+6 SO3-2 ------> these are the ions and their chargesCr+6 SO3-2 SO3-2 SO3-2 ----> the charges have to add up to zero, so three +2 sulfite ions cancels out one +6 Cr ion.Cr(SO3)3 ----> simplify
Formula: SO3

SO3 is sulfur trioxide.
The balanced equation for the reaction between SO3 and H2O is: SO3 + H2O → H2SO4

SO3 is the sulfate radical; it contains sulfur and oxygen.
Al2(SO3)3 = aluminum sulfite
Formula: SO3
The are two elements in SO3: sulfur and oxygen.
Sulfur trioxide
