H2SO4+ Mg > H2 + MgSO4
From the acid (or the water with which the acid is diluted).
The reaction will yield magnesium nitrate and hydrogen gas. Mg + 2HNO3 --> Mg(NO3)2 + H2
magnesuim does not have a smell
AKEM
Formula: MgI2
If the acid is hydrochloric acid, then the gas is hydrogen.
A salt. The type of salt depends on the type of acid.
gas and acid
Hydrogen chloride is a gas, Hydrochloric acid is the acid. ( difference is in solution )
Hydrogen gas is produced when an acid reacts with a metal. This is because the acid reacts with the metal to form a salt and hydrogen gas.
When sulphuric acid is added to zinc granules , the gas produced is hydrogen gas. Zinc displaces hydrogen from sulphuric acid.
When metals are put in hydrochloric acid, hydrogen gas is produced as the metal reacts with the acid to form metal chloride and hydrogen gas as a byproduct.
