Homework Help: Chem Equation

Posted by alisha on Thursday, January 4, 2007 at 7:58pm.

In a lab expirement you add copper(II)nitrate to pure zinc. Write a balanced equation for this expirement and predict if a reaction will occur.

Zinc is more active than copper, so zinc will donate electrons to the copper ions, precipating it as copper.

Cu(NO3)2 (aq) + Zn (s) = Cu (s) + Zn(NO3)2
