Hydrogen gas (H2) is always produced when a metal reacts with water.

When a metal reacts with water, it undergoes a redox reaction, where it loses electrons and is oxidized. The electrons are transferred to the oxygen atoms in the water molecules, which are reduced. The electrons released by the metal are used to break the O-H bonds in the water molecules, resulting in the formation of hydrogen gas. The balanced chemical equation for this reaction is:

2M + 2H2O → 2MO + H2

where M represents the metal.

What product are formed when a metal carbonate reacts with an acid?

When a metal carbonate reacts with an acid, the products formed are a salt, carbon dioxide gas, and water. The metal from the carbonate combines with the acid to form a salt, carbon dioxide gas is released as a byproduct, and water is also produced in the reaction.


What chemicals are produced when an acid reacts with a metal carbonate or hydroxide?

Generally, when an acid reacts with a metal carbonate, the products, the reaction products are: water, carbon dioxide, and a salt specific to the metal and the acid, e.g: hydrochloric acid + sodium carbonate → sodium chloride + carbon dioxide + water. 2HCl + Na2CO3 → 2NaCl + CO2 + H2O Generally, when an acid reacts with a metal hydroxide, the products, the reaction products are: water, and a salt specific to the metal and the hydroxide, e.g: Cupric hydroxide + hydrochloric acid → Cupric chloride + water Cu(OH)2 + 2HCl → CuCl2 + 2H2O
