Based on the chemical equation, use the drop-down menu to choose the coefficients that will balance the chemical equation: ()na2hpo4 → ()na4p2o7 + ()h2o

(2)Na2HPO4 → (1)Na4P2O7 + (1)H2O

The chemical reactions lab we did is typically called a "copper plating lab,  because the acid solution cleaned the pennies and made the copper look shinier;   the acid solution cleaned the paperclips and made them look like pennies;   &   the copper from the pennies was removed, and then added to the paperclips.
