Strong Acids:

* Hydrochloric acid (HCl): Reacts with most metals to produce hydrogen gas and a metal chloride salt.

* Sulfuric acid (H₂SO₄): Reacts with many metals, especially in dilute form, to produce hydrogen gas and a metal sulfate salt.

* Nitric acid (HNO₃): Reacts with many metals, but the reaction is complex and often produces nitrogen oxides and water instead of hydrogen gas.

Weak Acids:

* Acetic acid (CH₃COOH): Reacts slowly with some metals, like magnesium and zinc, to produce hydrogen gas and a metal acetate salt.

* Citric acid (C₆H₈O₇): Found in citrus fruits, can react with some metals, but the reaction is usually very slow.

* Carbonic acid (H₂CO₃): Formed when carbon dioxide dissolves in water, can react with some metals, like iron, to produce hydrogen gas and a metal carbonate salt.

Note: The reactivity of an acid with a metal depends on various factors, including the type of metal, the concentration of the acid, and the temperature. Some metals, like gold and platinum, are very resistant to acids.

It's important to remember that reactions between acids and metals can be hazardous, releasing flammable hydrogen gas. Always handle acids with caution and in a well-ventilated area.
