SO2 plus H2O equals H2SO3 which is Sulfurous Acid. CO2 plus H2O equals H2CO3which is Carbonic Acid. It also forms HNO3 which is nitric acid.
Sulfur TriOxide
H2so3 -----> so2 + h2o
s2o6
H2so3--------------------------------2h+ + (so3)2-
Na2SO3 + 2HCl -> 2NaCl + H2SO3
2KOH + H2SO3 --------> K2SO3 + 2H2O or K2O + SO2 ------> K2SO3
the equation for the decomposition of lead ii nitrate by heating is: 2Pb(NO3)2 - - - ->2PbO + 4NO2 + O2
Na2CO3-----------Na2O + CO2
H2so3--------------------------------2h+ + (so3)2-
H2o+so2=h2so3.....
Decomposition equation:2 NF3 ----> N2 + 3 F2
Na2SO3 + 2HCl -> 2NaCl + H2SO3
H2SO3 --> H2O + SO2
