reaction 1) CO2(g) bubbling off during the formation of Trisodium citrate:
C6H8O7 + 3NaHCO3 = 3CO2(g) + 3H2O + Na3C6H5O7

reaction 2) H2(g) bubbling off during the formation of Magnesium chloride:
Mg + 2HCl = MgCl2 + H2(g)

Answer 2

For the first i don't know the structure of neither of them so i can not help you.

For the second one if the Mg is a strong reducing agent it will combine with HCl to produce Hidrogen gas and
Magnesium (II) Chloride. If not for this reaction to occur you will have to supply current which is a flow of electrons and it will happen.
