1. Zn + 2 HCl → ZnCl2 + H2
2. Treating of aluminum powder with NaOH or KOH solutions.
2 Al + 6 H2O + 2 NaOH → 2 NaAl(OH)4 + 3 H2
Aluminium2 Al + 6 H2O + 2 OH− → 2 Al(OH)−
4 + 3 H2
You can prepare hydrogen in a bunch of different ways; many metals combine with certain acids to yield hydrogen gas in a single replacement reaction. One easy and quick way to produce it is to combine aluminum foil with a concentrated sodium hydroxide (NaOH) solution. This yields the salt sodium aluminate and hydrogen, and it does it much more quickly than the metal to acid reaction.
Two simple methods are:
- reaction of zinc with hydrochloric acid
- reaction of aluminium with sodium hydroxide
You can prepare hydrogen by adding magnesium to hydrochloric acid. hydrochloric acid + magnesium = magnesium chloride + hydrogen.
ductility is a property of a solid, and since hydrogen doesn't form a solid under natural or even laboratory conditions, it doesn't apply
0.666 ml in 999.34 distilled water
1 part of hydrogen peroxide out of 30% hydrogenperoxide bottle add 10 parts of distilled water
"electrifying water to separate the oygen and the hydrogen" (aka electrolysis) is very expensive and is only used to create laboratory grade hydrogen. According to this source: http://www.thenewatlantis.com/publications/the-hydrogen-hoax most commercial hydrogen is created from hydrocarbons, like natural gas and petroleum byproducts. The author of this article claims that creating hydrogen this way creates more CO2 than burning the hydrocarbons for fuel directly.
copper doesn't displace hydrogen from acids
Because they have a more efficient way of doing it.
Hydrochloric acid is prepared by dissolving hydrogen chloride gas in water. Hydrogen chloride is a covalent compound, but when dissolved in water it ionizes to form hydrogen ions and chloride ions as follows: By Kuldeep K. bansal INDIA
no-AH
just use the hydrogen cylinder
You can prepare hydrogen by adding magnesium to hydrochloric acid. hydrochloric acid + magnesium = magnesium chloride + hydrogen.
good
Hydrogen is not radioactive.
You have to ensure there is good ventilation when you prepare chlorine in a laboratory because chlorine is toxic so you need to ventilate it to avoid breathing it in.
You can prepare 13-dibromopropane in the laboratory from lower alkanes or alkyl halides using HBr in the presence of peroxide.

Yes, they did. Laboratory experiments showed them the results.
