When Calcium react with Copper(II) Nitrate, the balanced equation is simply:
Ca(s) + Cu(NO3)2 (aq) --> Ca(NO3)2(aq) + Cu(s) [no gas produced]
Why is it that hydrogen gas is also produced in the same reaction:
Ca(s) + 2H2O(l) --> Ca(OH)2(aq) + H2(g)
What would then be the complete balanced equation for the reaction between Calcium and Copper(II) Nitrate when there are 2 different reactions occuring in one chemical reaction?
Hence how do I determine when the water in an aqueous solution will or will not have a reaction to produce a gas in all other chemical reactions? Do aqueous solutions have any specific reactions in chemical reactions?
