This is a little known example of Schroedingers Pinnochio. His nose both grows and doesn't grow at the same time.

There was a Doctor Who sory I read once (I'm not sure if it was a TV episode or not) which had Silicon based Alien invaders.

My hangover cure is to drink water with a soluble vitamin C tablet in it, along with vitamin B complex. If I'm drinking again the next day, then a pint as soon as possible after waking works well (although it seems to be frowned upon by the medical commuity). If I'm not drinking the next day a lie in in a dark room works.

You can also use calibre to convert RTF Word documnents to mobi format.

One of the problems I've seen with people saying that they're against cencorship is that it may lead to abuse of free speech. IMO making (for example) racist comments is not acceptable, even though the racist would claim free speech.

I've just realised I forgot the word not in that first sentence Is it possible to edit post6s by the way?

Shark certainly is not a relic of a dinosaur, it's a fish! Crocodiles a reptiles, which aren't descended from dinosaurs, and a Komodo (I believe) is a lizard, again not descended from dinosaurs. With respect to geological formations, then I'd suggest that somewhere with lots of igneous rock is unlikely to have fissils as the lava would melt them! Sedimentary rocks would be more likely.

Molecules could exhibit Van der Waals forces, dipole-dipole attractions and hydrogen bonding between them. Ions would exhibit electrostatic attraction between them.

a) is a moles question. Calculate the number of moles of HCl, then using a balanced equation work out the moles of Na2CO3. Once you've got the moles, you can work out the mass. b) use your answer to part a to answer part be as a percentage.

or: the indicator is used to tell when the sodium hydroxide has been completely neutralized.

Think about the definition of an acid, then the formulae of the two acids.

It could be an osmosis experiment, where the OP needs to calculate the concentration of the potato.

At normal temperature and pressure it's going to go the other way: H2O2 -> H2O + O2 The question is whether it is an equilibrium reaction, so can uthe equilibrium be shifted the other way by changing the temperature and/or pressure (using Le Chateliers principle)

The first step (not the last step) is the slow, rate determining step.

Do you have an example of the type of question you're referring to?
