8. Acid indigestion can occur when the stomach produces too much hydrochloric acid, HCI. An old and effective remedy for this involves drinking a solution of
baking soda (sodium hydrogen carbonate, NaHCO3), which reacts with the
hydrochloric acid to produce sodium chloride (NaCl), water, and carbon
dioxide. Write the balanced equation for this reaction.

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
