Answer:

2AgNO₃ + CaCl₂ ⟶ 2AgCl + Ca(NO₃)₂

Explanation:

Put a 1 in front of the most complicated-looking formula [Ca(NO₃)₂)]:

AgNO₃ + CaCl₂ ⟶ AgCl + 1Ca(NO₃)₂

Balance Ca:

Put a 1 in front of CaCl₂.

AgNO₃ + 1CaCl₂ ⟶ AgCl + 1Ca(NO₃)₂

Balance N:

Put a 2 in front of AgNO₃.

2AgNO₃ + 1CaCl₂ ⟶ AgCl + 1Ca(NO₃)₂

Balance O.

Done.

Balance Ag.

Put a 2 in front of AgCl.

2AgNO₃ + 1CaCl₂ ⟶ 2AgCl + 1Ca(NO₃)₂

Every formula now has a coefficient. The equation should be balanced.

Check:

Atom On the left On the right

Ag 2 2

N 2 2

O 6 6

Ca 1 1

Cl 2 2

The balanced equation is

2AgNO₃ + CaCl₂ ⟶ 2AgCl + Ca(NO₃)₂
