Double Decomposition of Sodium Chloride and Silver Nitrate?? Help

1, WHAT HAPPENS WHEN TWO MIXES TOGETHER AND WHAT TWO PRODUCTS DOES IT PRODUCE ALONG WITH THE PRODUCT COLOUR,STATE AND CLARITY

2, BALANCE EQUATION

THANKS

It is not a double decomposition. It is a double replacement or double substitution.

1. Supposing the two reactants are in solution: When they mix a precipitate of silver chloride results. When it is fresh, silver chloride is a white solid, but on prolonged exposure to light it darkens. The supernatant liquid is clear and contains dissolved sodium nitrate.

NaCl + AgNO3 = NaNO3 + AgCl
