The correct answer is C) Hydrogen. When metals react with acids, the primary gas produced is hydrogen. This reaction typically involves the displacement of hydrogen from the acid by the metal. The metal ions from the metal compound combine with the anions from the acid to form a salt, while hydrogen gas is released.
For example, when metals like zinc, magnesium, or aluminum react with hydrochloric acid (HCl), the reaction proceeds as follows:
Zn + 2HCl → ZnCl2 + H2
Mg + 2HCl → MgCl2 + H2
2Al + 6HCl → 2AlCl3 + 3H2
As seen in the reactions above, hydrogen gas (H2) is released as a product when metals react with acids.
