Question

Aluminum hydroxide + calcium  =

Answer 1

I am just confused on one thing. Is the Aluminum Hydroxide writted in a chemical equation as AlOH or is is Al(OH)3(small 3)

Answer 2

When an equation, any equation is written the elements must be compounded right and so Al(OH)3 should be correct?

Answer 3

according to this page

http://en.wikipedia.org/wiki/Aluminum_hydroxide

it's \(\Large \text{Al(OH)}_{3}\)

Answer 4

Yes, because it is unpossible for the compound to our without the 3 OH's

Answer 5

I have one more question

Answer 6

Aluminum essentially always has an oxidation state of +3, because it loses control of its 3 valence electrons, so it would be Al(OH)3.

Answer 7

I am learning how to predict the type of reaction when certain elements and compounds are put together, i have a question --- water reacts to form ...--- and i have to predict the type of reaction - what type whould it be

Answer 8

As for the reaction, calcium is more active metal than aluminum:

Al(s) -> Al+3(aq) + 3e E0 = -1.66V
Ca(s) -> Ca+2(aq) + 2e E0 = -2.87V

So...in principle the calcium can reduce the aluminum:

3 Ca(s) +2 Al(OH)3 -> 3 Ca(OH)2 + 2 Al(s)
