Solution

Solution Steps

Step 1: Understanding Reactivity with Acid

Reactivity with acid refers to how a metal reacts when it comes into contact with an acid. This reaction often produces hydrogen gas and a salt. The reactivity of metals with acids can be ranked based on their position in the reactivity series.

Step 2: Reactivity of Aluminum with Acid

Aluminum reacts with acids like hydrochloric acid to produce aluminum chloride and hydrogen gas. This reaction is generally vigorous due to aluminum's position in the reactivity series.

Step 3: Reactivity of Magnesium with Acid

Magnesium is highly reactive with acids. When magnesium reacts with hydrochloric acid, it produces magnesium chloride and hydrogen gas. This reaction is typically more vigorous than that of aluminum.

Step 4: Reactivity of Copper with Acid

Copper is a less reactive metal and does not react with dilute acids like hydrochloric acid under normal conditions. It is below hydrogen in the reactivity series, meaning it does not displace hydrogen from acids.

Final Answer

Aluminum: Reacts with acid to produce hydrogen gas.
Magnesium: Reacts vigorously with acid to produce hydrogen gas.
Copper: Does not react with dilute acid.

\[ \boxed{ \begin{align_} \text{Aluminum:} & \text{ Reacts with acid} \\ \text{Magnesium:} & \text{ Reacts vigorously with acid} \\ \text{Copper:} & \text{ Does not react with dilute acid} \end{align_} } \]
