Homework 4: Unit 2 Part 2: Chemical Reactions Hints are given in some of the problems to get you started. By the time you get to taking the exam, those hints will not be there so you should be able to do these problems without the hints. 1. Balance the following chemical reaction using the smallest possible integer coefficients. AgNO, (aq) + Cu (s) - Cu(NO3)2 (aq) + Ag (s) 2. Write a balanced equation for the reaction described, using...
