Question

making activity series predictions
use the activity series below to predict the products of each of the following reactions. do not worry about balancing the equations.
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

1. $zn_3(po_4)_2 + ca \

ightarrow ?$
no reaction
$znca + po_4$
$ca_3(po_4)_2 + zn$

1. $agcl + na \

ightarrow ?$
no reaction
$nacl + ag$
$agna + cl_2$

Explanation:

Step1: Compare metal reactivity

From the activity series: $\text{Na} > \text{Ag}$

Step2: Predict single displacement

A more reactive metal (Na) replaces less reactive metal (Ag) in the salt.

Answer:

NaCl + Ag
