The test of completeness in the chemical changes experiment determines whether the NH3 is in excess. Which of the following statements is consistent with this idea? If NH3 is in excess, the next thing to do is add more Zn(s) to the sample. If NH3 is in excess, all Cu has been reduced. If NH3 is a limiting reactant, you'll get Zn(NH3)42+ before adding excess NH3. If NH3 is in excess, a blue complex, Zn(NH3)42+, is formed.
