Given the following aqueous reactants write a balanced chemical equation to describe the reaction that occurs when they are mixed. Include the formulas and physical states of each reactant and product. If there is no product state that "no reaction" will occur. (Do not write ionic equations for each)

a) Sodium chloride and silver nitrate

b) copper (II) chloride and sodium nitrate

c) potassium hydroxide and ammonium chloride

a) You need to write the balanced equation for sodium chloride `(Na Cl)` and silver nitrate (`Ag NO_3` ), such that:

`Na Cl + Ag NO_3 --> AgCl + NaNO_3`

During this equation, a white precipitate is formed and it is called silver chloride AgCl.

b) You need to write the balanced equation for copper (II) chloride (`CuCl_2` ) and sodium nitrate(`NaNO_3` ), such that:

`CuCl_2 + 2NaNO_3 --> Cu(NO_3)2 + 2NaCl`

c) Ammonium chloride (`NH_4Cl` ) solution does not react  with  potassium hydroxide (`KOH` ).

Actually, NH4Cl and KOH will react with each other.  NH4Cl contains the ammonium ion (NH4+).  This is mildly acidic and will release a proton to produce ammonia (NH3).  The hydroxide from the KOH will react with the proton to produce water.  The balanced chemical equation is below:

NH4Cl + KOH --> H2O + KCl + NH3
