Which of the following metals can displace hydrogen from acids?

Which of the following metals can displace hydrogen from acids?

Step 1: Understand what it means to displace hydrogen from acids. This means that a metal can replace hydrogen ions in an acid solution.
Step 2: Know that some metals are more reactive than others. More reactive metals can displace hydrogen, while less reactive metals cannot.
Step 3: Identify the metals in the question: zinc, copper, gold, and silver.
Step 4: Check the reactivity of each metal. Zinc is more reactive than hydrogen, while copper, gold, and silver are less reactive.
Step 5: Conclude that zinc can displace hydrogen from acids, but copper, gold, and silver cannot.
