Question

1. Name two metals which react with cold water to form hydrogen.
2. Name two metals which react with steam and displace hydrogen.​

Answer 1

Answer:

Answer:Metals like aluminium ,iron and zinc do not react with hot or cold water. But they react with steam to form metal oxide and hydrogen.

Answer 2

Explanation:

The alkali metals (Li, Na, K, Rb, Cs, and Fr) are the most reactive metals in the periodic table - they all react vigorously or even explosively with cold water, resulting in the displacement of hydrogen.

Metals like aluminium ,iron and zinc do not react with hot or cold water. But they react with steam to form metal oxide and hydrogen.
