Have I got this right?

[Louey]

I'm doing a balanced chemical equation for the reaction that occurs when solid barium hydroxide dissolves in water. Have I done this right (sorry not yet got to grips with the subscripts so saying subn when I need to!)

 

Ba(OH)sub2 --> Ba2OHsub2

 

If I have gone the wrong way can someone direct me where I have gone wrong so I can understand what I am not doing.

 

Thank you

not technically correct. rewrite as

 

Ba(OH)2 --> Ba2+ + 2OH-

[Hero]

when those elements are combined with water, they simply become ionized and the bonds between the barium and hydroxide are ripped apart.

[dryan]

Ba(OH)2 --> Ba2+ + 2OH-

 

Correct, but by putting (s) and (aq), it tells the reader that the material is in the solid form or in the aqueous form.

[Bryn]

why not just put [math]Ba(OH)_{2(s)} + (aq) \rightarrow Ba(OH)_{2(aq)}[/math]. Far simpler and does exactly what is says on the tin.

Because that's not what the homework requires; whilst it's adequate shorthand, it's useless for establishing a grounding in the mechanisms of aqueation.

both imply the same thing. it's like drawing organic compounds

the notation C-C-C implies propane.

the notation

H H H

H-C-C-C-H

H H H

also implies propane. both are accurate. both mean exactly the same thing.

eh pretend that second propane structure actually worked...

[Louey]

reading through this is actually very helpful so thank you for continuing this thread - I've got some compounds to figure too lol

If you use the [code/code] BB tags, you can make a block of monospaced text. All characters will take up the same horizontal space, and spaces will not be collapsed.

 

Handy for things like propane structure

good call. thanks
