How can the table be used to predict whether or not a metal will dissolve in HCl? In HNO3?

Drag the terms on the left to the appropriate blanks on the right to complete the sentences.

In general, metals whose reduction half-reactions lie ___. In general, metals whose reduction half-reactions lie blankthe reduction of H+to H2in the table will dissolve in acids, while metals ___ it will not. An important exception to this rule is ___, which can oxidize metals. Because Ered?of this half-reaction is ___, ___ can oxidize metals (copper, for example) that can't be oxidized by ___. Words: HCL Above Below Positive Negative HNO3
