Question

Definition of double displacement reaction and examples

Answer 1

Answer:

When a chemical reaction occurs, bonds are broken and new bonds are formed and products have a different identity from the reactants. In this lesson, we will discuss one of the main types of chemical reactions, called a double displacement reaction.

Explanation:

The reaction between silver nitrate and sodium chloride is a double displacement reaction. The silver trades its nitrite ion for the sodium's chloride ion, causing the sodium to pick up the nitrate anion.

AgNO3 + NaCl → AgCl + NaNO3

Here's another example:

BaCl2(aq) + Na2SO4(aq) → BaSO4(s) + 2 NaCl(aq)
