Question

reactions
predict the products of the double replacement reactions given. check to see that the equations are balanced.
$\text{agno}_3 + \text{nacl}
ightarrow ?$
$\text{agna} + \text{clno}_3$
$\text{nano}_3 + \text{agcl (s)}$
$2\text{nano}_3 + 3\text{agcl (s)}$
$\text{ag} + \text{nano}_3$

Explanation:

Step1: Identify double replacement pairs

In double replacement, cations/anions swap: $\text{Ag}^+$ pairs with $\text{Cl}^-$, $\text{Na}^+$ pairs with $\text{NO}_3^-$.

Step2: Form valid products

$\text{AgCl}$ is an insoluble solid (precipitate), $\text{NaNO}_3$ is soluble.

Step3: Balance the equation

Count atoms: 1 Ag, 1 N, 3 O, 1 Na, 1 Cl on both sides. Equation is balanced: $\text{AgNO}_3 + \text{NaCl}
ightarrow \text{NaNO}_3 + \text{AgCl (s)}$

Answer:

$\text{NaNO}_3 + \text{AgCl (s)}$
