Question

What type of reaction does the following equation represent?
AgNO3 + NaCI > AgCI + NaNO3

A. Synthesis
B. Combustion
C. Single-displacement reaction
D. Double-displacement reaction

Answer 1

This reaction above is considered a double-displacement reaction, so letter D. Ag reactions with Cl and Na reacts with NO3, they basically swap during the double replacement.

Answer 2

Answer: D. Double-displacement reaction

Explanation: Synthesis reaction is one which two or more substances combine to form a single product.

$A+B\rightarrow AB$

Combustion is a reaction in which a substance combines with oxygen gas to produce carbon dioxide, water and a lot of heat.

A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution.

$A+BC\rightarrow AC+B$

A double displacement reaction is one in which exchange of ions take place.

$AgNO_3+NaCl\rightarrow AgCl+NaNO_3$
