For each of the following reactions do the following: 1) Predict the products, 2) write chemical formulas for each compound, 3) balance the reaction for charge and mass and 4) Tell if the reaction will exist.

Solution

Mercury(II)sulfate + Zinc-----------------

Mercury(II) sulfate= HgSO4

ZInc= Zn

HgSO4(aq)   + Zn(s) -------------------- ZnSo4(aq) + Hg(l)

Hg+2(aq)   + SO4-2(aq) + Zn(s) -------------- Zn+2(aq) + SO4-2(aq) + Hg(l)

The above reaction is exist.Because according to electrochemical series Zn is present above the Mercury.

The above element can displaces the below element from thier aqueouus solution as a metal.
