Iron reacted with a strong acid would probably be cheapest, but aluminum reacted with sodium hydroxide solution is commonly used when hydrogen needs to be produced at remote sites like for weather balloons. Iron only reacts slowly with acid but the reaction between aluminum and sodium hydroxide is very rapid (and dangerous if it is not carefully controlled) producing large quantities of hydrogen. 1 mole of Aluminium will produce 1.5 moles of hydrogen gas or about 1 liter of hydrogen gas for every gram of aluminum.

Word equations for metal reactions?
metal + acid -> salt + water metal + oxygen -> metal oxide metal oxide + acid -> salt + water metal + water -> metal hydroxide + hydrogen Metal + Steam -> Metal Oxide + Hydrogen Metal + Acid -> Metal salt + Hydrogen
Is hydrogen a non metal?
yes hydrogen is a non metal
What reacts with a metal to form hydrogen gas and a metal?
An acid will react with a metal to form hydrogen gas and a salt of the metal. The metal replaces the hydrogen in the acid, leading to the formation of hydrogen gas which is released as a product of the reaction.
What is displaced from hydrogen when you add a reactive metal?
When you add a reactive metal, such as sodium or potassium, to hydrogen, the metal displaces the hydrogen gas and forms a metal hydride. This reaction is a displacement reaction where the metal takes the place of hydrogen in the chemical compound.
Is hydrogen a metal or nonmetal or feeling does it belong to?
Hydrogen is a nonmetal. It is placed in the upper left corner of the periodic table, making it part of the nonmetal group of elements.
Is hydrogen metals and nonmetals?
Hydrogen, symbol H, atomic number 1, is a non metal.
Is hydrogen metal?
Hydrogen is not considered a metal. It is a non-metal and is the first element on the periodic table. In its pure form, hydrogen exists as a diatomic gas and is the most abundant element in the universe.
