Question

An element x' after reacting with acids liberate hydrogen gas and can displace lead and tin from their salt solution. Write down the name of x metal.

Answer 1

Answer:Zinc

Explanation: In the reactivity series of metals Zn lies above lead and tin

Answer 2

The element x' that liberates hydrogen gas when reacting with acids and can displace lead and tin from their salt solutions is zinc (Zn).

• Zinc is a moderately reactive metal that can produce hydrogen gas (H2) and a zinc salt when it reacts with diluted acids like hydrochloric acid (HCl). Lead and tin can be replaced by zinc to create zinc salts because zinc is more reactive than those metals.

• Metals are a group of elements distinguished by their high melting points, capacity to conduct electricity and heat, and metallic lustre. They are crucial parts of many commonplace items, including electronics and coins, and have a wide range of applications in industry, technology, and construction.
