AgNO3+HCI=AgCI+HNO3

The equation you provided represents a double displacement reaction, also known as a double replacement reaction. In this particular reaction, silver nitrate (AgNO₃) reacts with hydrochloric acid (HCl) to produce silver chloride (AgCl) and nitric acid (HNO₃). Here’s how it can be balanced:

Unbalanced Equation: \[ \text{AgNO}_3 + \text{HCl} \rightarrow \text{AgCl} + \text{HNO}_3 \]

Balanced Equation: The equation is already balanced as written:

1 silver (Ag) on each side. 1 nitrate (NO₃) on each side. 1 chloride (Cl) on each side. 1 hydrogen (H) on both sides.

Thus, the balanced equation is: \[ \text{AgNO}_3 + \text{HCl} \rightarrow \text{AgCl} + \text{HNO}_3 \]

This reaction is commonly used to demonstrate the formation of a precipitate, as silver chloride (AgCl) is insoluble in water and precipitates out of the solution.
