Question

Write the balanced molecular equation for each reaction. (Use Na+ and NO3? as the spectator ions. Use the lowest possible coefficients. Include states-of-matter under SATP conditions in your answer.)

(a) BaCrO4(s)
(b) AgCl(s)
(c) CaSO4(s)
(d) Hg2Cl2(s)

Explanation / Answer

For PbCl2 you could start with Sodium Chloride and Lead Nitrate (both soluble) 2 NaCl(aq) + Pb[NO3]2(aq) > PbCl2(s) + 2 Na[NO3](aq) A net ionic equation for this would be: 2 Cl^-1(aq) + Pb^+2(aq) > PbCl2(s) For BaCrO4 use Na2[CrO4] and Ba[NO3]2 (both soluble) Na2[CrO4](aq) + Ba[NO3]2(aq) > Ba[CrO4](s) + 2Na[NO3](aq) You can write the net ionic equation. For Fe[OH]3 use Na[OH] and Fe[NO3]3 For PbSO4 use Na2[SO4] and Pb[NO3]2
