3. When a solution of sodium hydroxide is mixed with iron (II) chloride, a green precipitate is formed. What is the balanced equation for that reaction? O Fe2Cl(aq) + NaOH(aq) → Fe2OH(aq) + NaCl(a)
O Fe2 C (mg) + NaOH(aq) → Fe2OH(aq) + NaCl(aq)
O FeCl2(98) + NaOH(aq) → Fe(OH)2() + NaCl(ed)
O FeCl2(aq) + 2 NaOH(aq) → Fe(OH)2(8) + 2 NaCl(a)

The lattice enthalpy (formation of ionic solid from ions in the gas phase) for agcl(s) is -916 kj/mol and the hydration enthalpy (dissolution of gaseous ions into water) is -850 kj/mol. how much heat (in joules) is involved in forming 1l of saturated agcl solution (1.8 × 10-4 g / 100 ml water) by dissolving agcl(s)? assume solution volume does not change much upon dissolution. the equations are given below. ag+(g) + cl−(g) æ agcl(s)
