Good question there. :rolleyes:

How do you know? Or did you just use a calculator.

Girls are so easy to flatter.

Yeah but that doesn't stop the fact that the guy is an idiot.

Are you talking about the conditions? outline the steps and conditions necessary for the industrial production of H2SO4 from its raw materials or describe the steps and chemistry involved in the industrial production of H2SO4 and use available evidence to analyse the process to predict...

What an idiot.

Mine's starting tomorrow.

Yeah, thanks for deleting the post I put so much effort into.

Threshold frequency: the minimum frequency of a photon that can eject an electron from a surface Work function: the minimum energy needed to remove an electron from within a solid to a point outside its surface in a vacuum. So it can be seen that threshold frequency and work function are...

The specific term of threshold frequency is not in the syllabus but I guess it's assumed that you know it in order to understand the photoelectric effect which is of course addressed in the syllabus.

You deserve a medal.

I think you're right. 2*5! = 240, which is not right.
