Carbon dioxide.
Remember the general rule for acids and carbonates.
Acid + Carbonate = Salt + Water + Carbon Dioxide.
e.g.
2HCl + CaCO3 = CaCl2(Salt) + H2O + CO2 ( using a mineral acid)
2CH3COOH + Na2CO3 = 2CH3COONa + H2O + CO2 ( using an organic acid).
Notice in both cases the gas , Carbon Dioxide (CO2) is liberated.
The last example above, can be conducted at homem using Vinegar(Acetic (Ethanoic) Acid ) and Washing soda(Soda crystals),Sodium Carbonate.
You will know it has reacted, by seeing 'effervescence/fizzing'.
the acid eats the meatl
When a metal reacts with dilute hydrochloric acid, hydrogen gas is produced. This is because the metal displaces hydrogen from the acid, forming metal chloride and releasing hydrogen gas.
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.
Zinc is a metal that reacts with dilute sulfuric acid to produce hydrogen gas.
When a metal oxide reacts with an acid, a salt and water are formed as products. Additionally, carbon dioxide gas may be produced if the metal oxide is a carbonate.
hydrogen gas
zinc reacts with dilute HCl to form H2. This works to reduce (add Hydrogens to ) a compound
Hydrogen gas is produced when a metal reacts with a dilute acid. This reaction occurs when the metal displaces hydrogen from the acid, forming metal salts and releasing hydrogen gas as a byproduct.

Hydrogen is produced, as illustrated with the metal zinc: Zn + 2 HCl -> ZnCl2 + H2.
When a metal reacts with dilute hydrochloric acid, hydrogen gas is produced. This is because the metal displaces hydrogen from the acid, forming metal chloride and releasing hydrogen gas.
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.
Zinc is a metal that reacts with dilute sulfuric acid to produce hydrogen gas.
This depends on the metal in reaction.
When a metal oxide reacts with an acid, a salt and water are formed as products. Additionally, carbon dioxide gas may be produced if the metal oxide is a carbonate.
When a metal carbonate reacts with an acid, the products are a salt, carbon dioxide gas, and water. The salt formed will depend on the specific metal in the carbonate and the acid used in the reaction.
