Question

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

1. $zn_3(po_4)_2 + ca \to ?$

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

1. $agcl + na \to ?$

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 replaces a less reactive metal in a salt. Sodium replaces silver in $\text{AgCl}$.
<Expression>$\text{AgCl} + \text{Na}
ightarrow \text{NaCl} + \text{Ag}$</Expression>

Answer:

NaCl + Ag
