What reacts with sulphuric acid to produce hydrogen gas?
Metals such as zinc, iron, and aluminum react with sulfuric acid to produce hydrogen gas along with the corresponding metal sulfate salt. The reaction involves the displacement of hydrogen from the acid by the metal.
What is the substance in limestone that reacts with acid?
Limestone is basically Calcium Carbonate(CaCO3). The metal part(Calcium) is the reactive part in it. It reacts with acids as well as bases. For example, it reacts with Hydrochloric acid to form calcium chloride whereas reacts with Ammonium hydroxide to form Calcium Hydroxide.
When calcium is exposed to air what happens?
When calcium is exposed to air, it reacts with the oxygen in the air to form calcium oxide. This reaction produces a layer of white calcium oxide on the surface of the calcium metal, which is commonly known as calcium oxide or quicklime. This layer of calcium oxide can help protect the underlying calcium from further oxidation.
What happens when calcium metal is added to a dilute solution of hydrochloric acid?
When calcium metal is added to a dilute solution of hydrochloric acid, a chemical reaction takes place in which calcium reacts with hydrochloric acid to produce calcium chloride and hydrogen gas. The balanced chemical equation is: Ca (s) + 2HCl (aq) -> CaCl2 (aq) + H2 (g)
What happens when carbon dioxide react with oxides of metal?
When carbon dioxide reacts with oxides of metals, it can form carbonates. The reaction typically involves the displacement of oxygen in the metal oxide by carbon dioxide, resulting in the formation of metal carbonates. This type of reaction is often used in various industrial processes, such as in the production of calcium carbonate from calcium oxide.
