Final answer:
The balanced chemical equation is Cu + NF3 → CuF2 + N2F4
Step-by-step explanation:
The balanced chemical equation for the reaction between copper metal and nitrogen trifluoride is:
Cu + NF3 → CuF2 + N2F4
The reaction involves copper (Cu) reacting with nitrogen trifluoride (NF3) to produce copper(II) fluoride (CuF2) and nitrogen tetrafluoride (N2F4).
