The most common one would be carbon dioxide, which is given off when strong acids react with rocks containing carbonates.
Hydrogen gas is given off when magnesium reacts with sulfuric acid.
Hydrogen gas is given off when ethanoic acid (acetic acid) reacts with magnesium. This is a result of the displacement reaction between the acid and the metal.
No acid is formed. The reaction produces hydrogen gas and magnesium chloride, a salt.
carbon dioxide. CO32- + 2H+ -> CO2 + H2O
Hydrogen. The same is true for when most metals react with an acid.
Carbon dioxide gas is given off when a carbonate reacts with dilute hydrochloric acid. This reaction results in the formation of a salt, water, and carbon dioxide gas.
Hydrochloric acid gives off hydrogen gas when it reacts with certain metals, such as magnesium or zinc. When hydrochloric acid reacts with limestone (calcium carbonate), carbon dioxide gas is produced.
Carbon dioxide gas is given off when an acid reacts with carbonates. This reaction forms carbonic acid, which then decomposes to release carbon dioxide gas.
Hydrogen gas is given off when copper reacts with hydrochloric acid (HCl) according to the reaction: Cu + 2HCl -> CuCl2 + H2.
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.
Depends on the acid and alkali. But in most cases Hydrogen or Carbon Dioxide.
Without the list of rocks we cannot respond to this question.
