 Ca(OH)2(aq) + 2NH4Cl 一> CaCl2(s) + 2H2O(l) + X. In the reaction above, X is 

A. NO2

B. NH3

C. N2O

D. N

The correct answer is B. NH3

In the reaction between calcium hydroxide and ammonium chloride
 the product X is ammonia gas.
NH3Reactants: You have a base (Calcium Hydroxide, 
  • Ca(OH)2cap C a open paren cap O cap H close paren sub 2
    ) and an ammonium salt (Ammonium Chloride,
    NH4Clcap N cap H sub 4 cap C l
    ).
  • Products: The reaction forms Calcium Chloride (
    CaCl2cap C a cap C l sub 2
    ) and water (
    H2Ocap H sub 2 cap O
    ).
  • Balancing the Equation: To balance the atoms, the nitrogen and hydrogen from the ammonium chloride combine with the hydroxide to form ammonia (
    NH3cap N cap H sub 3
    ) and water, with the chlorine pairing with calcium.     
  • Past Question Number: 30
  • The balanced equation is:
Ca(OH)2(aq)+2NH4Cl(s)→CaCl2(s)+2H2O(l)+2NH3(g)cap C a open paren cap O cap H close paren sub 2 open paren a q close paren plus 2 cap N cap H sub 4 cap C l open paren s close paren right arrow cap C a cap C l sub 2 open paren s close paren plus 2 cap H sub 2 cap O open paren l close paren plus 2 cap N cap H sub 3 open paren g close paren
