Question

enter the compound that forms between sodium and carbonate. express your answer as a chemical formula. a chemical reaction does not occur for this question. part b enter the compound that forms between sodium and phosphate. express your answer as a chemical formula. a chemical reaction does not occur for this question.

Explanation:

Step1: Determine ion charges

Sodium ion ($Na^+$) has a +1 charge, carbonate ion ($CO_3^{2 -}$) has a - 2 charge.

Step2: Balance charges

To balance the charges, we need 2 sodium ions for every 1 carbonate ion. So the formula is $Na_2CO_3$.

Step3: For sodium - phosphate

Sodium ion ($Na^+$) has a +1 charge, phosphate ion ($PO_4^{3 -}$) has a - 3 charge.

Step4: Balance charges for sodium - phosphate

To balance the charges, we need 3 sodium ions for every 1 phosphate ion. So the formula is $Na_3PO_4$.

Answer:

Part A: $Na_2CO_3$
Part B: $Na_3PO_4$
