Determine if HNO3 can dissolve in the following metal:
1) Write a balanced chemical reaction showing how the 2.09g Cu dissolves in HNO3.
I had put down: Cu(s) + 4HNO3(aq) ——> Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l)
but it's wrong.
2) Determine the minimum volume of 6.3M HNO3 required to completely dissolve the sample (in mL).
The reaction of copper metal with a dilute nitric acid will take place according to the following equation: 3Cu(s) + 8HNO3(aq) ——> 3Cu(NO3)(aq) + 2NO(g) + 4H2O(l)
To calculate the amount of material we need copper:
