Question
PROBLEM-SOLVING EXAMPLE 3-8 Classifying Reactions by Type
Classify each of these reactions as one of the four general types discussed in this
section,
a. 2 Al(s) + 3 Br,(€) Al,Br,(s)
b. 2 K(s) + H,O(e) 2 KOH(aq) + H,(g)
c. AGNO,(aq) + NaCl(aq)
d. NH,NO,(s) - N,0(g) + 2 H,O(g)
AgC(s) + NANO,(aq)
Strategy and Explanation Use the fact that in displacement reactions, one reactant is
an element, and in exchange reactions, both reactants are compounds.
a. With two reactants and a single product, this must be a combination reaction.
b. The general equation for a displacement reaction, A + XZ AZ+ X, matches
what occurs in the given reaction. Potassium (A) displaces hydrogen (X) from
water (XZ) to form KOH (AZ) plus H, (X).
c. The reactants exchange partners in this exchange reaction. Applying the general
equation for an exchange reaction, AD + XZ AZ + XD, to this case, we find
A is Ag*, D is N0, X is Nà", and Z is Cl.
d. In this reaction, a single substance, NH,NO,, decomposes to form two products,
N,0 and H,O.
Answer
a. Combination
b. Displacement
c. Exchange
d. Decomposition
