    Any Predictions for specific topics(questions) which can come for the Physics AS level paper 2 exam?

    For waves I've seen a pattern. Most likely stationary waves might come or related to diffraction. Projectile motion is also recently being asked. It can come also.

    Chemistry Paper 2

    Trust me I've done a whole lot of pp and in our course we have never said that Ar makes covalent compounds as you suggest that the activation energy is high. It was for only 2 mark i guess and you had to right it is 1)unreactive/inert 2) As it has a complete octet/stable electronic...

    Chemistry Paper 2

    No it was as, Ar is inert because it has a complete octet of electrons/ stable electronic configuration.
