Answer 2

Sodium will displace hydrogen from acids to liberate hydrogen gas as a product since Sodium is more reactive than hydrogen.

Also, copper will displace hydrogen from acids to produce hydrogen gas though copper is not more reactive than hydrogen.

However, gold and silver won't displace hydrogen from acids and liberate hydrogen gas as a product.
