The enthalpy change of hydrogenation of benzene was shown to be less exothermic than 3 times that of hexene, therefore meaning that benzene does not contain three double bonds. X-ray imaging showed that b...

Hempel’s analytic behaviourism is the view that mental states are a private phenomenon, so cannot be verified in a public, intersubjective sense. Thus, we have to talk about them in terms that are empiric...

In cyclohexa-1,3,5-triene the molecule has 3 single bonds and 3 double bonds where all the electrons are localised. As a result the energy needed to hydrogenate cyclohexa-1,3,5-triene is (3x -120kJ/mol) =...

a) It is useful to rewrite the equation using power rules, so we get y = 2x³ + 3x^-2Now we can simply use the differentiation rules where we multiply the coefficient (number before x)...

Application of suvat equation v=u+at. Students acknowledge that at the rocket's maximum height it will have a velocity of 0. They also realise that the time to reach thi s point from launch is half ...
