Hydrogen
Hydrogen gas is given off when magnesium reacts with sulfuric acid.
AgNo3 (aq) + HCl (Aq) -> HNO3 (aq) + AgCl (s) there's no gass given off, only solid and aquous substances.
No acid is formed. The reaction produces hydrogen gas and magnesium chloride, a salt.
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.
Hydrogen. The same is true for when most metals react with an acid.
When dilute hydrochloric acid reacts with sodium carbonate, the gas given off is carbon dioxide. This reaction can be represented by the following equation: 2HCl + Na2CO3 -> 2NaCl + H2O + CO2.
Hydrogen gas is given off when magnesium reacts with sulfuric acid.
hydrogen eg:Na+HCl------>NaCl+H2
AgNo3 (aq) + HCl (Aq) -> HNO3 (aq) + AgCl (s) there's no gass given off, only solid and aquous substances.
carbon dioxide. CO32- + 2H+ -> CO2 + H2O
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 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.
Hydrogen. The same is true for when most metals react with an acid.
I assume you mean this reaction. Mg + 2HCl -> MgCl2 + H2 That is hydrogen gas being given off. ( H2 )
Hydrogen gas is given off when sodium hydroxide reacts with a metal. This is due to the displacement reaction that occurs where the more reactive metal displaces hydrogen from water molecules in the sodium hydroxide solution.
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.
