(Cu(s) + 4 HNO₃(aq) → Cu(NO₃)₂(aq) + 2 NO₂(g) + 2 H₂O(l))
a) Write the net ionic equation for the reaction of concentrated nitric acid with solid copper...
a) (Cu²⁺ + 2 NO₃⁻ + 2 H₂O → 2 NO₂ + 2 H₂O)
b) (Cu(s) + 4 H⁺ + 2 NO₃⁻ → Cu²⁺ + 2 NO₂ + 2 H₂O)
c) (Cu(s) + 4 H⁺ + 2 NO₃⁻ → Cu²⁺ + 2 NO₂ + 2 H₂O)
d) (Cu²⁺ + 2 NO₃⁻ + 2 H₂O → Cu(s) + 4 H⁺ + 2 NO₂)
