if calcium carbonate is heated in oxygen, will it form calcium peroxide aswell as/ instead of calcium oxide?

ok thanks, are there any others while i'm at it?

i need a chemical reaction which (if possible) would normally take place at high temperatures but, with the addition of a catalyst, takes place at room temperature (or as close to it as possible) and is easily demonstrated in a lab. any suggestions?

but is urea itself explosive? because in dynamite the sawdust doesnt react with the explosive, it is just a filler, wouldnt the paper be the same (if urea is explosive)

ok, i see your point, but anyway, are you saying that it would not explode?

i read somewhere that electrolysis of urea solution can produce hydrogen, but what are the other products?

in the 007 film 'the world is not enough' a man is killed by exploding money. it is later explained that the money had been dipped in urea, and one of the metal strips in the money had been replaced with magnesium, and the man had a radiotransmitter on him which set it off. i am a bit sceptical and would like to know if this would work... firstly, wouldn't it need to be in a sealed container for it to explode? secondly, would the magnesium strip ingnite from a radio transmitter? and if so wouldn't it ignite from all the other radio signals travelling around MI6's headquarters?

ok, thankyou

since X rays have more energy than UV rays, does that mean that they will cause the same chemical reactions as UV but faster?

i was just looking at sodium carbonate on wikipedia and under melting point its says: 851 °C (anhydrous) 100 °C (decomp, monohydrate) 34 °C (decomp, decahydrate) i don't know what monohydrate or decahydrate means, but does that show that if it was in aqueous solution it would decompose at a lower temperature? or am i misunderstanding this? Merged post follows: Consecutive posts mergedand when it decomposes would it decompose to sodium hydroxide?

oh ok that helps a it thankyou

why is air opaque to those wavelengths?

is there a way of removing carbon dioxide from sodium carbonate without having to react it with anything e.g. by heating it?

can an element which is more electronegative displace a less electronegative element in a covalent bond?

so anything under 190nm will do?

if you have a shorter wavelength of UV, will more ozone be produced than if you have a longer wavelength?

never mind, it doesn't matter anymore, i made a mistake somewhere n ended up with the wrong products :S but thanks anyway

in a lab experiment, how would one separate a mixture of N20, NO2, NO and CO?

ok, what is hc and what is E?

oh ok thankyou, is it the same with the hydrogen then?

when you electrolyse water, does the oxygen at the anode stay as atomic oxygen (O) or combine to form molecular oxygen (O2)?

does UV radiation have the ability to break up water molecules? if so please specify the wavelength

would you be able to explain that in a bit more detail?

hahaha

i read somewhere that when (dilute?) acid is added to chlorophyll, the magnesium ion is removed. but it doe snot go into detail and i cannot find it anywhere else. can someone tell me which acids this is and explain the mechanism and/or provide and equation please?
