Sas. g) Element Q reacts with dilute acids but not with cold water. Element R does not react with
dilute acids. Elements S displaces element P from its oxide. P reacts with cold water. Arrange
the four elements in order of their reactivity, starting with the most reactive.​

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

the right answer is c i just did the question.
