Classify each of the following as a redox reaction or a non-redox reaction.
zn+cucl2 -> zncl2+cu hcl+naoh -> h2o+nacl 2co+o2 -> 2co2 so3+h2o -> h2so4

Zn+CuCl₂ -> ZnCl₂+Cu   Redox; Zn oxidized (0 to +2), Cu reduced (+2 to 0)
HCl+NaOH -> H2O+NaCl   Non-redox
2CO+O2 -> 2CO2  Redox; C oxidized (+2 to +4), O reduced (0 to -2)
SO3+H2O -> H2SO4 Non-redox

If it isn’t a then it has to be d idk tho cause there’s no picture
