II. Additional tests needed to establish the exact position of hydrogen Step 1: Identify that to establish the exact position of hydrogen, we need to test its reaction with elements next to it in the series. Step 2: Suggest testing hydrogen's reaction with an element that is slightly less reactive than those it reacted with in the initial six test tubes. This would help determine if hydrogen is more reactive than those elements. Step 3: Also, suggest testing hydrogen's reaction with an element that is slightly more reactive than those it did not react with in the initial six test tubes. This would help determine if hydrogen is less reactive than those elements. III. Predictions for silver and magnesium reacting with dilute sulfuric acid Step 1: Recall that silver is less reactive than hydrogen, and magnesium is more reactive than hydrogen in the activity series. (a) For silver and dilute sulfuric acid: Step 2: Predict that silver will not react with dilute sulfuric acid since it is below hydrogen in the activity series. (b) For magnesium and dilute sulfuric acid: Step 3: Predict that magnesium will react with dilute sulfuric acid since it is above hydrogen in the activity series.
