You get an reaction on witch the result is Hydrogen . It was an old metod of producing hydrogen gas use by early balloons and dirigibles. Of cousre is not ane reliable "economic" solution so this days was forget. But you can fous it on books along with the other way of producing hydrogen by miging sulfuric acid with iron.

What is the strongest acid on the pH scale?
Carborane acid is the world's strongest acid, followed by fluorosulfonic acid. The acidity of carborane acid has been shown at least a million times stronger than concentrated sulfuric acid, and hundreds of times stronger than the previous record holder fluorosulfonic acid.
How to convert benzynoic acid to phenol?
You must initially convert it into benzene then heat it with Zn dust. And add CH3-Cl+anhydrous AlCl3 followed by hot concentrated KMnO4.
How do you prepare 1M sulfuric acid from concentrated sulfuric acid?
To prepare 1M sulphuric acid from concentrated sulphuric acid:First consider the molecular weight of H2SO4 = 98 g/mol, so you have to add 98g of conc. acid and make up to 1 liter of water (as pointed out at the 4thpoint).Considering that acid is a liquid, you should also consider density: where density = mass/volume, which is said on the bottle to be (about) 1.84 g/mL,so then you have: volume = 98g / 1.84(g/mL) = 53.2 mLNow you have to consider the acid purity, usually 98% then you have to do this: 53.2 mL if the acid were 100% pure convert in mL given with the purity of 98%, so 100% x 53.2 mL / 98% = 54.3 mL of (98%) concentrated acid.Finally CAREFULLY add this 54.3 mL (or 98 g, cf. first point) to about 0.9 L dist. water while continuously stirring (evolving heat!), and after that fill it up to 1.00 L with also dist. water. Never reverse this: DO NOT add water to concentrated fluids!
How do you convert 1 chloropropane to 2 chloro propane with structure?
React with alcoholic KOH (dehydrohalogenation) to give 1-propene, followed by treatment with HCl (electrophilic addition).
Is it salf to drink hydrogen peroxide?
It's not a good idea. From the web site of the CDC (Center for Disease Control): Ingestion of dilute solutions of hydrogen peroxide may result in vomiting, mild gastrointestinal irritation, gastric distension, and on rare occasions, gastrointestinal erosions or embolism (blockage of blood vessels by air bubbles). Ingestion of solutions of 10-20% strength produces similar symptoms, but exposed tissues may also be burned. Ingestion of even more concentrated solutions, in addition to the above, may also induce rapid loss of consciousness followed by respiratory paralysis.
Another word for followed up with?
Try "in addition to" or "followed by".
