A bit of history might be helpful here: back in the 1800's a Scottish guy by the name of James Clerk Maxwell came up with a theory of electromagnetism which was so successful that pretty much everyone thought it was going to be the last word. For example, he predicted that electromagnetic...

I borrowed a copy from my local library. Read it. Thought it was OK - not as good as Hawking's "A Brief History of Time". Returned it. Why buy it?

OK - confession time. I've been teaching Physics on and off for over 20 years and I only got my head around the Twin Paradox after reading an article in Scientific American Feb2006 Special Edition, which you can access through the Ebsco online database. My problem with the Twin Paradox was...

Sugar cane contains sugars, one of which is glucose C6H12O6. C6H12O6 -> 2C2H5OH + 2CO2 (fermentation reaction). Yeast changes the glucose into ethanol C2H5OH. I think the syllabus is referring to the increasing number of transuranic elements (I think we're up to 118). These elements are...

Thermite can create temperatures well over 1000 C. Wait until you've got a B.Sc. in Chemistry (or equivalent) before you muck around with this one. A splotch of molten iron in your face will ruin your whole day (and a fair bit of the rest of your life).

Both HCl and CH3COOH are monoprotic acids i.e. when they react with a base, they can do so with one proton (H+) per molecule. The fundamental reaction is the same in both cases: acid + base = salt + water. The application of Le Chat's principle is a bit of a strange idea to be tacked on, but...

[b]gather, process and present information from secondary sources to describe the steps and chemistry involved in the industrial production of H2SO4 (Hydrogen Sulphate) and use available evidence to analyse the process to predict ways in which the output of sulfuric acid can be maximised.[b]...

Wood or timber is a good choice on this one. On the "evaluate the progress currently being made to solve the problems identified" bit you can approach it in a couple of ways: 1. Lots of trees are being planted to replace the ones that get cut down 2. Other materials e.g. concrete and...
