Examine the reactants of the incomplete double displacement reaction.
Elza [17]
<h3>Answer:</h3>

The products of the reaction are; AgCl and  NaNO₃

<h3>Explanation:</h3>

In this question we need to know what is a double displacement reaction;

  • A double displacement is a type of replacement reaction in which salts or ionic compounds exchange cations and anions to form new compounds as the products.
  • In this case, the complete double replacement reaction is;

AgNO₃(aq) + NaCl(aq) → AgCl(s) + NaNO₃(aq)

  • The reaction is also a precipitation reaction as it forms a precipitate as one of the products that is silver chloride (AgCl).
  • Therefore, the products of the reaction are; AgCl and  NaNO₃
