WHAT IS THE BALANCE REACTION FOR THE REACTION BETWEEN COPPER AND TRIOXONITRATE(V)ACID

1 answer

I suppose that funny named chemical you mean to be HNO3. The IUPAC names that nitric acid. There are two equations. One is with dilute HNO3 and other with concentrated HNO3.
For concentrated HNO3:
Cu + 4HNO3 ==> Cu(NO3)2 + 2NO2 + 2H2O
For dilute HNO3:
3Cu + 8HNO3 ==> 3CuNO3)2 + 2NO + 4H2O
Check that out. Make sure those equations are balanced. My typos can be bad sometimes.
