Mg (s) + 2 HCl (aq) --> H2 (g) + MgCl2 (aq)
Hydrogen
Zinc + hydrochloric acid = zinc chloride + hydrogen
The balanced chemical equation is: Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g) The products formed are zinc chloride and hydrogen gas.
When chlorine gas is mixed with hydrochloric acid, it forms chlorine gas and water. This reaction releases heat and can be quite exothermic. It is important to handle chlorine gas and hydrochloric acid with caution, as both are toxic and can be harmful if inhaled or touched.
*when putting a piece of magnesium into dilute hydrocloric acid . *then hydrogen gas bubbles off. *this shows that magnesium react quickly in acid.
Hydrogen is produced, as illustrated with the metal zinc: Zn + 2 HCl -> ZnCl2 + H2.
When hydrochloric acid and iron react, it results in the formation of iron(II) chloride and the release of hydrogen gas as a byproduct. The reaction can be represented by the following chemical equation: 2 HCl + Fe → FeCl2 + H2.
Mg + H2SO4 -> MgSO4 + H2 Hydrogen gas.
Hydrogen and the ( name of metal ) chloride, sulphate or nitrate. eg Hydrocloric acid and iron - hydrogen and iron cholride
When silverbackium reacts with nitric acid, nitrogen dioxide gas is formed along with other products.
Matter can neither be created nor destroyed. However zinc does react with hydrochloric acid, producing zinc chloride and hydrogen gas. The hydrochloric acid isn't destroyed, only changed into something else.
Hydrocloric asid
No gas. Acid + base --> salt + water only
