you can get hydrogen when you make a metal react with acids or water such as when potassium or sodium is made to react with water it burns with a lilac colored flame and gives of hydrogen. but the reaction is very explosive and violent. If u use calcium instead of it .This wont be a vigorous reaction but the calcium is expensive. You can get hydrogen from zinc easily if you make it react with dil.HCl or dil.H2So4(sulphuric acid)
It makes Sodium Chloride (Salt) and Hydrogen
Sodium will react with virtually any acid to produce hydrogen gas. However the heat produced by such a reaction usually ignites the hydrogen.
Potassium will react with nitric acid to produce potassium nitrate and hydrogen gas. 2K + 2HNO3 --> 2KNO3 + H2
Insoluble metal oxide + strong acid ---> salt + water
It will react to make explosive hydrogen even water will do the trick.
Acid will make a salt of that metal and free hydrogen, from the acid, if that metal is lower then hydrogen in the electro- motive series

An acid plus a metal produces a salt of the acid plus Hydrogen gas. 2HCl + 2Na ---> 2NaCl + H2
Sodium will react with virtually any acid to produce hydrogen gas. However the heat produced by such a reaction usually ignites the hydrogen.
Copper is unreactive and will not react with acids to liberate hydrogen gas. However it may react if concentrated and oxidising acids are used.
Yes, many metals can react with acids.
You can throw a piece of metal into the acid (magnesium will have good effect), as it is dissolving, hydrogen gas would be given off...
There is no such thing as Sodium Hydrochloric acid, but if you react Sodium metal with Hydrochloric acid, you will release hydrogen. The hydrogen comes from hydrochloric acid, which is HCl (hydrogen chloride.) Sodium is Na, just a pure element without any hydrogen in it. 2Na + 2HCl --> 2NaCl + H2 (gas) You don't need HCl to make hydrogen gas. Just tossing the sodium into water will release plenty of hydrogen (and some flames) and give a solution of sodium hydroxide in the water.
M stands for the metal and HA stands for the strong acid where H is hydrogen and A is the anion (the other ion) of the acid. MCO3 + HA --> MA + H20 + CO2 (H2CO3 is formed as the other product but it splits up into carbon dioxide and water). This is a double replacement reaction where the metal bonds with the anion of the acid and the hydrogen bonds with the carbonate ion. Also I didn't balance the equation but I think this should help you understand the concept.
Potassium will react with nitric acid to produce potassium nitrate and hydrogen gas. 2K + 2HNO3 --> 2KNO3 + H2
