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

The balanced chemical equation for the reaction you mentioned is:

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

To balance this equation, we need to ensure that the number of each type of atom is the same on both sides of the equation. Here's how you can balance it:

Let's start by looking at the number of atoms of each element on both sides of the equation:

On the left-hand side (reactants):
1 H atom (from HCl)
1 Cl atom (from HCl)
1 Ag atom (from AgNO3)
1 N atom (from AgNO3)
3 O atoms (from AgNO3)

On the right-hand side (products):
1 H atom (from HNO3)
1 N atom (from HNO3)
3 O atoms (from HNO3)
1 Ag atom (from AgCl)
1 Cl atom (from AgCl)

To balance the equation, we can follow these steps:

1. Balance the chlorine (Cl) atoms by putting a coefficient of 1 in front of HCl:

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

2. Balance the silver (Ag) atoms by putting a coefficient of 1 in front of AgNO3:

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

3. Balance the nitrogen (N) atoms by putting a coefficient of 1 in front of HNO3:

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

4. Balance the hydrogen (H) atoms by putting a coefficient of 1 in front of HCl:

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

Now the equation is balanced, and it shows that 1 mole of HCl reacts with 1 mole of AgNO3 to produce 1 mole of HNO3 and 1 mole of AgCl.
