You can write any equation you want to; that doesn’t mean the reaction proceeds thusly. Type of Chemical Reaction: For this reaction we have a chemical reaction. The equation you show can be balanced this way: 3 CuS + 14 HNO3 → 3 Cu(NO3)2 + 8 NO + 3 H2SO4 + 4 H2O. But the H2SO4 shows that it is not in base medium. Cu(g) + 2H2SO4(l) --> CuSO4(aq) + SO2(g) + 2H2O(l) Since the number of atoms of each element of the reaction arrow is equal (Cu=1, S=2, H=4, O=8), hence the chemical equation is balanced.
