question 14 of 22 general chemistry 4th edition mcquarrie • rock • gallogly university science books presented by macmillan learning determine the chemical formula for each of the compounds. sodium sulfite: naso₃ potassium phosphate: k₃po₄ silver sulfate: asso₄ ammonium nitrate: (nh₄)no₂

Explanation:

Step1: Determine sodium sulfite formula

Sodium has a +1 charge ($Na^+$) and sulfite ion ($SO_3^{2 -}$) has a - 2 charge. To balance the charges, we need 2 sodium ions. So the formula is $Na_2SO_3$.

Step2: Check potassium phosphate formula

Potassium has a +1 charge ($K^+$) and phosphate ion ($PO_4^{3 -}$) has a - 3 charge. We need 3 potassium ions to balance the charge, and the given formula $K_3PO_4$ is correct.

Step3: Determine silver sulfate formula

Silver has a +1 charge ($Ag^+$) and sulfate ion ($SO_4^{2 -}$) has a - 2 charge. We need 2 silver ions, so the formula is $Ag_2SO_4$ (the given $AsSO_4$ is incorrect as silver symbol is $Ag$ not $As$).

Step4: Determine ammonium nitrate formula

Ammonium ion ($NH_4^+$) has a +1 charge and nitrate ion ($NO_3^-$) has a - 1 charge. The correct formula is $NH_4NO_3$ (the given $(NH_4)NO_2$ is incorrect as the nitrate ion is $NO_3^-$ not $NO_2^-$).

Answer:

sodium sulfite: $Na_2SO_3$
potassium phosphate: $K_3PO_4$
silver sulfate: $Ag_2SO_4$
ammonium nitrate: $NH_4NO_3$
