When HNO3 and Au are mixed together, what do you expect to happen, and why?
No reaction, because Au is above H on the activity series and they cannot react
No reaction, because Au is lower on the activity series and cannot replace H
They form Au(NO3)2 and H2, because Au is more reactive and able to replace H
They form Au(NO3)2 and H2, because they trade places in a double replacement reaction
