Question

making predictions about reactions
complete the following equations (note that the equations are not balanced). use the activity series if necessary.
li > k > ba > sr > ca > na > mg > al > mn > zn > cr > fe > cd >
co > ni > sn > pb > h > sb > bi > cu > ag > pd > hg > pt > au
al + agcl → ?
$ce{alcl3 + ag}$
$ce{alag3 + cl2}$
no reaction
$ce{alcl + cl}$

Explanation:

Step1: Compare metal reactivity

From the activity series: $\text{Al} > \text{H} > \text{Ag}$, so $\text{Al}$ is more reactive than $\text{Ag}$.

Step2: Predict single displacement

Aluminum will displace silver from silver chloride.

Step3: Write balanced product formula

Aluminum forms $\text{Al}^{3+}$, chloride is $\text{Cl}^-$, so the product is $\text{AlCl}_3$, plus elemental $\text{Ag}$.

Answer:

A. $\text{AlCl}_3 + \text{Ag}$
