Chemical Diagrams.

[girlsaloud]

I'm really stuck, and I have no Idea how to draw chemical diagrams, although I do see them at the back of the class room. What I wanted to know is, how do you make a chemical diagram such as

O

/ \

H H

 

^Like that. But for this chemical equation?

 

2AL + 2KOH + 6H20 + (heat) - > 2KAI (OH) 4 + 3h2

the line connecting the oxygen atom and hydrogen atoms you showed in yoru diagram means covalent bonds between atoms, so you could just draw such diagram with covalent compounds; with ionic compounds, you could simply draw two ions, for instance, for NaCl, you may just write Na+Cl-; while for a bit complicated ionic compound such as NH4MnO4, if you like, you may draw,

H

|

[H-N-H]+

|

H

for ammonium ion; and

O-

|

[O=Mn=O]

|

O

for manganate(VII) ion;

if what you would like to represent is simple element, you may just write its element symbol.
