The Group 1 metal 'Francium;. because it is radio-active, and you don;t want radio-active material splashing everywhere.
Hydrogen is an element that is too dangerous to add to dilute sulfuric acid.
This is to dilute the sulphuric acid. Sulphuric acid in high concentrations is dangerous and very corrosive.
Concentrated sulfuric acid has sulfuric acid molecules where dilute sulfuric acid has sulfate ions and hydrogen ions. Water in the diluted solution acts as the ionization medium.
It depends on how diluted the dilute sulphuric acid is (i.e. its concentration).
Driving off the water from dilute sulfuric acid will increase the concentration of the acid to the point where it will contain virtually no water.
Dilute means that something is in a mixture. In this case it is a mixture of sulfuric acid and water which are both compounds.

No, although "concentrated" sulfuric acid (essentially pure H2SO4) is less dissociated than dilute sulfuric acid, simply because there's no water around for it to dissociate in.

Dilute sulfuric acid is still acid. It is NOT basic at all.

Concentrate Sulfuric Acid is more dangerous as it is a purer substance. Anything which is dilute has been diluted (mixed) with another substance, usually water.
You need to remove the water by evaporation.
Copper does not react with dilute Sulphuric acid.
The answer depends on the dilution factor and if the sulfuric acid was 100% to start.
The most fizzing will come from the concentrated sulfuric acid, then dilute sulfuric acid, then the acetic acid.The amount of fizzing is due to the concentration of H+ in the solution, and concentrated sulfuric acid has the most H+ in solution. The dilute sulfuric acid has less (because it is dilute) and the acetic acid solution has the least of all because it is a weak acid rather than a strong acid.See the Related Questions for more information.
