Balance this reaction: underline ( )Na_(3)PO_(4)+underline ( )KOHarrow underline ( )NaOH+underline ( )K_(3)PO_(4)^- 1,1,3,1 1,3,2,1 2,3,3,1 1,3,3

To balance the reaction, we need to ensure that the number of atoms of each element is the same on both sides of the equation.<br /><br />The unbalanced reaction is:<br />$Na_{3}PO_{4} + KOH \rightarrow NaOH + K_{3}PO_{4}$<br /><br />To balance the reaction, we need to adjust the coefficients of the reactants and products.<br /><br />The balanced reaction is:<br />$Na_{3}PO_{4} + 3KOH \rightarrow 3NaOH + K_{3}PO_{4}$<br /><br />Therefore, the correct answer is: $1,3,3,1$.
