I need to know the word equation and would like to also know what other chemicals are givin off during this experiment. What things take place( i know the reaction with water but i need to know the scientific way) . I hope you can also tell me how we know that there is more than one product even though we can see only one.

2Ca + 2H2O = 2Ca(OH)2
In the above equation you get only 2 moles of one product since Ca which is solid form is dissolved in H2O which in liquid form. However, if the same reactants are taken together at higher temperature(other than room temperature) we get the following:
Ca + H2O = CaO + H2(gas)
We get Calcium oxide and hydrogen gas

Calcium + water = calcium + water
Just kidding!! I really don't know.

Ca(s) + 2H2O(l)----------------Ca(OH)2(aq) + H2(g)
half rxns
ca(s)-------------ca+2 + 2e-
2H2O + 2e- ---------- H2 + 2OH-
--------------------------------------------
Ca(s) + 2H2O--------------Ca2+ + 2OH- + H2(g)
Ca(s) + 2H2O--------------Ca(OH)2 + H2(g)
