FeSO4 and Hydrogen sulphide
nitrogen and hydrogen reacted over an iron catalyst
Mg + H2SO4 -> MgSO4 + H2 Hydrogen gas.
34 grams of Ammonia
Probably nothing: Hydrogen is higher than copper in the electromotive series, so that copper can not displace hydrogen from its compounds,
strong acids like sulphuric acid reacted with metals like zincwater reacted with alkali metalselectrolysisetc.
Oxygen
Fluoride is an ion; it is basically fluorine that has already reacted. As such it is fairly stable. Elemental fluorine is much more reactive that carbon.
it reacted that way do to chemical reactions.
it depends on what chemical it has reacted to.
Oxygen
Hydrogen will be liberated.
Aluminum is a silvery metal that will evolve hydrogen gas when reacted with a strong acid. Aluminum will also evolve hydrogen gas as a product of its reaction with a strong acid.
The Hydrogen will burn fiercely with a lambent blue flame and water will be produced.
The iron in haemoglobin is reduced oxidised by the hydrogen peroxide which is an oxidising agent.
Hydrogen
