Hey!!

Could you please help me with the following:

What is Cl + H20?
What is P2O3 + H2O?
Is SIO a simple molecular structure?
Is Na2O an ionic structure?

Thanks!!

I can have a go at answering some of that I think... Cl2 + H20 is your classic disproportionation reaction: the chlorine is both oxidised and reduced in the same reaction. So you get:

Cl2 + H20 --> HOCl + HCl

Na2O is ionic. Na and oxygen have very different electronegativities.

P2O3 + 3H20 --> 2H3PO3 - *possibly*. The product is phosphorous acid, it does exist, I checked, but it may well be that the reaction is more complex than that. But I think that's right.

The other one - I'm not sure, I've never come across SIO - unless you mean SiO? (Or, surely, SiO2?)

Cl + H20 --- HCl + HCLO

SiO2(SiO doesnt normally exist) has a giant molecular structure
Na2o has an ionic structure

P2o3 doesnt normally exist either, it makes P4O6 or p4O10, and both of these make H3Po4 - phosphoric acid

Thanks for your help guys...much appreciated!

I've got one other Q:

How can you make magnesium oxide without using a direct combination of the elements?

Thanks!

Mg + H2O -- MgO + H2

That maybe? Dunno if thats classed as a direct combo or not

Thanks!
heat magnesium in steam- forms MgO
(if just react magnesium with water then will form Mg(OH)2 very slowly
