balance hcl(aq) + agno3(aq) yields hno3(aq) +AgCl (aq)

The given chemical equation represents a double displacement reaction between hydrochloric acid (HCl) and silver nitrate (AgNO3). The balanced chemical equation for the reaction is:

HCl(aq) + AgNO3(aq) → HNO3(aq) + AgCl(aq)

To determine the balanced equation, we need to make sure that the number of atoms of each element present on the reactant side is equal to the number of atoms of each element on the product side. Here's how to balance it step by step:

Step 1: Count the number of atoms of each element on both sides of the equation.

Reactant side:
H: 1
Cl: 1
Ag: 1
N: 1
O: 3

Product side:
H: 1
Cl: 1
Ag: 1
N: 1
O: 3

Step 2: Balance the elements one at a time, starting with the most complex molecule or polyatomic ion.

The number of Cl atoms is already balanced.

Step 3: Balance other atoms.

To balance the Ag atoms, we need to have the same number of Ag on both sides. So, we put a coefficient of 1 in front of AgCl on the product side.

HCl(aq) + AgNO3(aq) → HNO3(aq) + 1AgCl(aq)

Step 4: Finally, balance the remaining elements.

To balance the H atoms, we need to put a coefficient of 1 in front of HCl.

1HCl(aq) + AgNO3(aq) → HNO3(aq) + 1AgCl(aq)

The final balanced equation is:

HCl(aq) + AgNO3(aq) → HNO3(aq) + AgCl(aq)

It's important to note that the coefficients in front of the chemical formulas represent the number of molecules or moles of each substance involved in the reaction. Also, (aq) stands for aqueous, indicating that the substance is dissolved in water.
