An equation showing all dissolved compounds as ions
(Apex) Ions that do not participate in the reaction
These are contrary reactions.
heat
In this reaction a change of bonds of the reactants occur: the general form is:AB + CD = AD + BC
CaCO3 -> CaO + CO2
The products will contain the elements Na and O.
For Apex the answer is 2
The chemical equation is:SO2 + H2O ↔ (HSO3)- + H+The acid is hypothetic.
They will contain 18 atoms total in all the products.
