Ok the question is some what simple and difficult. I know there are certain rules like
a. A + B = AB (combination)
b. AB = A + B (decomposition)
c. AB + C = CB + A (substitution)
d. AB + CD = AD + CB (metathesis)
now the trouble i have is not in balancing the equation but figuring out what the out come of the reactants will be.
For example an unsolved and unbalanced equation.
___Ca(s) + ____H2O(l) ----> (?)
Why is the answer to the above question Ca(OH)2 + H2 and not CaO + H2...are there any particular rules i would have to know when figuring out the product of reactants.
Using the rules mentioned above would the following equation be right or wrong
___Al(s) + ____H2O(l) ----> (?)
result: 2Al + 3H2O ---> Al2O3 + 3H2
Also is there anything to do with classification of elements that change the out come of the product.
Thanks!
