Answer 1

Activity Series: clivity series: The series of elements in which they are arranged in the ascending order of Their rear known as activity series (OR) The elements can be arranged in the descending Sider of their reactivity also Rules . 1) Higher ove Higher clé Standard Recertion petential (SRP) Jalued elements should be placed at the top of the table. They au highly reactive métals. They can easily displace. I melals & H₂ which are below to it in the table. Higher tvé SRP valued elements should be places of the bottom of the table. Higher SRP is observed for non-metals. So, they can also highly reactive non- metals. 3) Sep value of 'H' is 'Zero'. The metals above the i 1. Can displace 'H į form acicls. 4) The metals which are below to H. they cannot - displace H₂ from acids.
