Can anyone help me to know about the reactants and the products of these reactions, I can't find what they are:
Na₂S₂O₇ -->
HSO₃Cl +. --> H₂SO₅ +...
Na₂S₂ +. --> Na₂S₂O₃
. + N₂H₄ --> HN₃ + H₂O
Ca₃(PO4)₂ +. +. --> CaSiO₃ + CO +...
CS₂ + Cl₂ --> CCl₄ +.
NaIO₃ + NaOH + Cl₂ --->. +.
If this is wrong to forum rules, plz give me the hints for each reaction, thanks a lot
