Peter Tse - Free Will: Where's the Problem?
Why is free will such a complex puzzle, enough to drive philosophers slightly mad? Free will probes consciousness, examines what it means to pick, choose, select, decide. But some say that 'free will' is just a trick of the brain. How to discern the key issues of free will, scientifically

Strong and Weak Alkali's | Acids, Bases & Alkali's | Chemistry | FuseSchool
An acid is a substance that will dissociate in water to give a proton (or H+ ion) and a conjugate base. An acid is considered to be strong if dissociation nears 100%, and weak if dissociation is usually less than 1%. In this lesson, we will learn about strong alkalis and weak alkalis.
