The balanced equation shows how sodium chloride reacts with silver nitrate to form sodium nitrate and silver chloride. NaCl plus AgNO sub 3 rightarrow NaNO sub 3 plus AgCl If 4 point 0 0 g of NaCl react with 10 point 0 0 g of AgNO sub 3 , what is the excess reactant?

The balanced equation has a 1:1 mole ratio between NaCl and AgNO₃. The amounts are 4.00 ÷ 58.44 ≈ 0.0684 mol NaCl and 10.00 ÷ 169.87 ≈ 0.0589 mol AgNO₃. Since there are fewer moles of AgNO₃, it is used up first, leaving NaCl in excess. The correct choice is NaCl.
