desperately need help with chemistry questions. (1 Viewer)

[samih91]

These three questions are in my chemistry assignment and i was wondering if anyone could help me desperately. Your help will be a lot. Thank you

• Identify three silver halides.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>

• Describe the changes that occur in one of the silver halides above when it is exposed to light.<o></o>
• Write an equation for this reaction in words and symbols.<o></o>

Ever heard of Google?

Now you have. Go look at the first link that comes up when you search "silver halide".

You do know halides are the halogen group on the periodic table right ?

As in Chlorine (Cl), Bromine (Br), Iodide (I) and so on and all their ions have a charge of -1 ... But Silver (Ag) ions has a charge of +1 ..

So they should look like:

Silver Chloride (AgCl)
Silver Bromide (AgBr)
Silver Iodide (AgI)

When you add valencies together e.g Ag⁺ + Cl^- --> AgCl

Oh yes Google would help ... and why is this in the HSC section ?
I don't recall seeing Silver Halides in the Excel HSC Chemistry study guide or HSC Conquering Chemistry textbook ...
I never heard of this silver halide stuff anyway.

sliver halide + light = silver metal (turn dark color)... reduction happened...

oxidation i am thinking happens to water...
