Copper Reactions Post Lab Questions: Make sure the reactions are balanced before
you do any calculations. To receive full credit, you must SHOW ALL OF YOUR WORK!!
For each of the following reactions, identify the category of reaction, balance thes
reaction, and describe how you knew a reaction took place. To indicate an already
balanced reaction, write balanced above the reaction.

Expert Solution
Step 1

Reaction 1;

HNO3(aq) + Cu(s)  -------->   Cu(NO3)2 (aq) +  H2O(l) + NO2 (g) 

Balanced reaction;

2HNO3(aq) + Cu(s)  -------->   Cu(NO3)2 (aq) +  2H2O(l) + 2NO2 (g) 

Reaction category : Oxidation reaction. 

The reaction identified as the solid Cu metal gets dissolved to form blue colored solution.
