and "It contains three molecules".

anonymous · Answer

It contains 3 molecules wouldn't be quite accurate. A molecule is something like H2O. And what is given in the question is itself a molecule. If there were 3 of them it would be: $$3Al(OH)_3$$

anonymous · Answer

so it has 3 OH??

anonymous · Answer

Yep. |dw:1364524588055:dw| The reason why it is 3 OH groups and not just 3 H is because of the parentheses around the (OH)

thank you

i am just bad at elements

anonymous · Answer

haha. It's okay, they can be tricky to understand at first. (though, it may be better to ask the chemical ones under the chemistry section in the future, they'll be more likely to explain things)

this is physics, Reactions and pereodic table element reactions.
